The Royal Institute of Technology of the Empire has been developing cement for a long time, and there are not too many restrictions on the licensing of cement technology, basically as long as you can afford the patent licensing fee, then you can get the license to produce, and the price is not too expensive.

However, in the early days, cement was limited by the high cost, and at first it was only used in small quantities for construction, and it was mainly for military construction, and only the military with deep pockets would not care about the high cost of cement and purchased and used it in large quantities.

In the private sector, only a small amount of construction is used, but these small uses are difficult to drive the development of the cement industry.

No matter what time a businessman is, he is profit-seeking and short-sighted, and when he sees no hope of making money, he will devote himself to other industries.

Of course, this is also the same as the current Tang Empire is at the beginning of the industrial revolution, it can be said that all walks of life are in a period of rapid development, and you can make money by doing anything.

Compared with industries such as cement, which have large investments and slow returns, businessmen are more willing to invest in industries with small investments and fast returns, especially those where others make a lot of money.

Follow the trend, this is the biggest characteristic of capital!

In the same way, this is why domestic capital is very favored by the textile industry.

The textile industry investment is small, and easy to operate, basically without any technology, as long as you register a company, find a plant, and then buy textile equipment, and then recruit a group of workers to be able to produce, and even the relevant middle and senior managers are a lot of grabs.

More importantly, whether it is the domestic market or the foreign market, the demand for textile products is still very strong, there are more than 150 million people in China, even if a large part of them still maintain the traditional life of male farmers and women weaving, will not directly buy cloth or clothes, but the urban population is not a small number, their demand for cloth and ready-to-wear is very large.

Moreover, when the merchants saw that they could not sell ready-made clothes in the countryside, and even the sales of cloth were very small, they simply sold cotton yarn directly.

Although women in the countryside also weave on their own, cotton is not produced in every place, and cotton yarn is sold directly to rural women, who then weave their own cloth and make it into clothes.

The huge population in China, coupled with the development of domestic people's livelihood in the empire for more than ten years, has gradually enriched the people's pockets, and the wealth of the people also represents consumption power.

Relying on the huge population in China, the textile industry has received excellent development opportunities, and the empire encourages maritime trade, and gradually opens up foreign markets, which also allows the textile industry of the Tang Empire to find a market.

In the foreign market, the merchants of the Tang Empire will not care so much, in order to seize the market, they use all kinds of messy methods, and the use of low-price dumping to suppress the local related industries are the lowest means, and after eliminating the local industry to obtain a monopoly, it is nothing to raise prices significantly.

The most important thing is that they will influence the local political situation in various ways, force the local market to open up, or simply help them monopolize the market.

Through various means, the textile products of the Tang Empire, along with other industrial products, poured into Fuso, various parts of the South Seas, India, and even parts of West Asia and North Africa.

As for Europe, this market is relatively special, the distance is too far, the transportation cost is too high, so it is difficult to rely on cheap industrial products to open the market, Datang in the European market mainly relies on silk and porcelain, the two magic weapons, as for tea, Europe is still in the tea consumption habit cultivation period, export volume is very limited.

In addition, the European market was largely dominated by the Portuguese and the Ottoman Empire, and although the Spaniards had joined in recent years, the Spanish fleet was too small to transport large quantities of goods.

As for Datang's own fleet, although it has also been there a few times, each time it is a small-scale exploratory trade, and it is not a climate.

Therefore, the Tang Empire's trade with Europe today has basically two models, one is to sell goods to the Portuguese, and then the Portuguese detour through southern Africa and ship them directly back to Europe.

The other way is to transport the Datang specialty goods to India, West Asia and other places through the Tang Western Trading Company, and then sell them to the Ottomans, and then the Ottomans transport them to the Mediterranean Sea by land, and sell them to Europe through the Mediterranean.

In these two ways, the Tang Empire can only play the role of a producer, and it is difficult to directly participate in the channel, let alone terminal sales.

Even now, the cooperation with the Spaniards is in this way.

The lack of colonies on the western coast of India, West Asia, and Africa and thus the lack of adequate supply ports were the main reasons hindering the Tang Empire's direct participation in European trade!

However, even so, the overseas trade of the Tang Empire is also booming, and the textile industry continues to maintain a very high growth rate.

Under this kind of big back, it is not difficult to explain why domestic capital is so keen on the textile industry, all kinds, large and small textile enterprises are springing up like mushrooms after a rain, some are engaged in spinning, some are engaged in weaving, some are engaged in printing and dyeing, some are engaged in garments, some are engaged in clothing, etc., and are engaged in wool, raw silk, and silk.

The above-mentioned textile industry has directly driven the development of many industries such as machinery, chemical industry, steel, shipbuilding, transportation, and energy!

Because the textile industry needs machinery and equipment for production, horse-drawn carriages and boats for transportation, and then further extends to the need for chemical raw materials, steel materials, wood, coal, and so on.

Otherwise, how could the textile industry be listed as a strategic development industry by the Ministry of Commerce of the empire, and called the leading industry of the empire's industry and commerce, this is because the textile industry can drive the development of a large number of related industries.

In the same way, this is also why in the original time and space, when various countries in the world carried out the industrial revolution, many countries started the industrial revolution from the textile industry.

The industrial revolution in European countries is mostly inseparable from the textile industry, and look at the rise of the British to know how strong their textile industry was during the industrial revolution.

Even Fuso and Huaxia, which are backward countries in East Asia, were already in the mid-19th century when they carried out industrial development, hundreds of years before the start of the industrial revolution, but they still chose the textile industry as a supporting industry.

When the Chinese people initially developed industry in the mid-to-late nineteenth century, they also took the textile industry as the absolute pillar industry.

The Fusang people exchanged raw silk for warships, and the Chinese people actually exchanged raw silk for warships, but our early development path was suspended due to internal strife and external troubles.

From the industrial revolution hundreds of years after the modern industrial period, the textile industry has an unshakable core position, this is beyond doubt.

The textile industry has a great future, which many people know, so a lot of capital has poured into it.

Of course, smart businessmen will also choose other related industries, and even some people will boldly enter heavy industries such as shipbuilding, shipping, machinery, steel, energy, etc.

However, cement is still not the first choice for many businessmen!

Although cement is also an emerging industry, many people are optimistic, but in the early years, cement was expensive and people were not familiar with this product, so the actual application scale was relatively small, and the only big customer was the military.

This situation in several major cities in China, the beginning of the use of cement paving is a change, directly with cement paving, which does not bring a broad market for cement, and then stimulates the rapid development of cement.

Until now, the empire has carried out large-scale infrastructure construction, especially the infrastructure construction of water conservancy facilities, which has completely detonated the cement industry.

Everyone is not stupid, many businessmen see that the cement industry has broad prospects, and they directly wave checks to enter the cement industry.

No technology? It doesn't matter, go directly to the Royal Institute of Technology to buy it, buy it first and produce it first, and then develop other cement products on your own.

Don't have a device? Needless to say, buy it anyway! As long as you have money, you can order any machinery you want from several major domestic machinery and equipment manufacturers.

Don't have a technician? Dig! Raise wages and poach people directly from existing cement manufacturers.

As for ordinary managers and workers, this is not a problem, as long as there is money to grab a lot of money!

You say that cement production can't be sold? What kind of international joke, don't you see that the empire is engaged in infrastructure construction, not to mention the rest, just the major water conservancy facilities announced by the empire are enough to feed the entire cement industry, not to mention that several major cities in China are now building cement roads one after another, in addition to the general construction industry has also begun to popularize cement on a large scale.

As long as the cement is produced and the quality is guaranteed, there will be absolutely no worries about sales.

Under this wave, in the second half of the 15th year of Xuanping, 26 cement factories across the country broke ground and were put into operation one after another.

The annual output of these 26 cement plants alone is as much as four times the annual output of cement in the past!

In other words, the cement industry was affected by the empire's vigorous construction of water conservancy facilities, and in half a year there was a growth rate of 400 percent!

However, its output is still unable to fill the huge demand for cement in the empire!

Sixteen years after entering Xuanping, there are still reports from all over the country that the cement plant was approved and then the construction began.

According to the report submitted by the Royal Institute of Technology, by the 16th year of Xuanping, a total of 38 enterprises had been granted cement patents, which is 38 enterprises, not 38 factories.

Many of the companies here can open multiple cement factories at the same time.

As long as you can afford to pay the patent licensing fee, the Royal Institute of Technology will not care about you, anyway, they charge royalties according to the output, and if you open ten or eight factories, they can collect more royalties, and they are even happier.

The outbreak of the cement industry is only an impact of the empire's large-scale infrastructure construction, not only the cement industry, but also the steel industry, coal, transportation and many other industries have been greatly affected.

However, the impact is not as great as that of the cement industry.

However, this does not mean that the steel and other industries have not developed, in fact, the development of steel and other industries is still very rapid, and its volume is much larger than that of a mere cement industry, and it is also more valued by Li Xuan.
