Chapter 394

The fate of the two Quan Zhiguozi supervising the sacrificial wine, as well as the unlucky young craftsman Chen Wenyong who wanted to steal the credit, really made Chen An, who has always been low-key and cautious in his words and deeds, really worried about Wang Yang's-stirring stick, and no one knew when he would be in trouble again.

Walking in the palace, although Chen Andao is an important minister of the court and often goes in and out of the palace, it is just a hall of a few deliberations at three points and one line, and as for many places in the palace, it is not for him to slip around casually.

If it weren't for Wang Yang's renovation of the toilet in the palace ban, I am afraid that he would not have had the opportunity to sneak into these places to hang out, and after thinking wildly, he rushed to the front of a thatched house under construction under the guidance of the little eunuch in the palace.

However, Wang Yang, a dignified eight-rank official, did not look like an official at all, he did not wear a black gauze hat on his head, and the official robe on his body was taken off and put aside.

And he was standing under the sun in a middle coat, pointing to the septic tank below, reasoning with the craftsmen.

"In a word, there must be two more bricks down from this position, and since this is the design drawing, then you must follow the design drawing."

"But in that case, you're going to waste half a little more...... The little ones just want to be able to save a little bit. The craftsman explained helplessly.

"I know your good intentions, but the problem is that if this position is too high, it won't have the effect of purification and decomposition......" Wang Yang didn't have the slightest official gesture there, while patiently discussing with the craftsman leader. It wasn't until he had persuaded the other party that he climbed up the wooden ladder.

But he really didn't expect that Chen Andao would actually appear here. After Wang Yang jumped up, he saluted directly to Chen Andao, who was walking slowly. "Master Chen, why are you here? Such a hot day......"

"It doesn't have to be like this, on such a hot day, the supervisor of your dignified right school order has worked so hard to share weal and butter with these craftsmen, what can't the old man come over to see." Chen Andao looked at Wang Yang with a smile.

I didn't expect that this guy would be so aggressive in the court, but when facing these lowly craftsmen and officials, he seemed very friendly.

"Haha, let me laugh. But Lord Chen, you came here in person, shouldn't it be just to have a look? Wang Yang snorted, a little puzzled about the intention of this master craftsman.

"You're really right, the old man is indeed a little curious, today I accidentally asked about the progress of the project on your side, but I heard that you now have a new adhesive, no need to use glutinous rice juice, which really makes the old man quite curious...... So I came here today to take a fresh look. ”

"Oh, you're here to see the effect of the Yuanyu cement, right?" Wang Yang nodded suddenly, raised his finger and pointed to the dozens of dusty oil-paper bags placed over there and said. "Those are the adhesives newly invented by Xia Guan: Yuanyou cement."

Chen Andao stepped forward and looked at the dusty oil-paper bags, all of which were covered with a layer of iron-gray fine dust. "These things, the old man really can't see them, but it feels a bit like the kind of dust that appears after the stonemason beats and crushes......"

"Boss, these are made of limestone as the main ingredient, and their effect is not inferior to that glutinous rice juice, and even surpasses it...... If you don't believe it, then please come with me and take a look, and you will know. Wang Yang led the way.

Chen Andao followed Wang Yang's footsteps and came to a toilet that had been renovated before, looking at this brand new and clean toilet, on the ground, there was a piece of iron-gray open space about five feet square with neat edges like stones.

"This is ......" Chen Andao saw Wang Yang who was smiling and groaning after standing there, his eyes fell on the open space under Wang Yang's feet, and his feet stepped on it, as if he was stepping on the hard stone slab, without a little softness of the mud.

"This is the ground formed by the hardening of cement, and it is not as strong as granite, but it is not too bad......"

"And you see, the filler for these wall joints is made of cement, fine sand mixed with water......"

Looking at this clean and smooth ground, as clean as a huge stone slab, Chen Andao even stomped hard with his foot, and the soles of his feet hurt faintly, but he didn't feel the slightest sign of cracking in the flat ground made of cement and fine sand under his feet.

"The old man heard that the Yuanyou cement you invented seems to be very cheap, and one stone of glutinous rice can be exchanged for two thousand catties of such Yuanyou cement?"

"Not bad." Wang Yang nodded and explained. "Although this cement is also made by firing, because it is made of concentrated firing, plus the limestone material in addition to the mining cost, there are only transportation costs, as well as the cost of mechanical wear and tear required for grinding, plus the fuel per thousand catties of cement, the total price is just the same as that stone glutinous rice."

"But when it is used, every two catties of cement and one catty of glutinous rice can play a binding effect, there is no difference, that is, a catty of glutinous rice mixed with ten catties of water can be boiled for an hour and a half after the bonding effect, two catties of cement is enough."

"As for the effect, you've seen it, and I'm sure you've felt the hardness......"

"What do you mean is that two thousand catties of cement can have the bonding effect of one thousand catties of glutinous rice, but their cost is only equivalent to one stone of glutinous rice......"

In the early years of the Northern Song Dynasty, a stone of rice was between 300 and 600 Wen, and in the Renzong period, it was between 600 and 700 Wen, and in this dynasty, a stone of rice was about the same money.

As for glutinous rice, because it is not only used for food, but also in construction, the demand for glutinous rice has always been not small, not only for winemaking, but also for food, and more importantly, for the construction industry.

This is why, in ancient China, except for a few city walls and necessary buildings that were made of brick and stone, most of them were completely wooden structures?

One of the biggest reasons for this is the lack of good and inexpensive adhesives. After all, the main function of glutinous rice is to eat it.

However, because of its stickiness, in some cases, it has to be used as an adhesive for buildings, and even for books, calligraphy and paintings, window paper, etc., this thing needs to be used.

Even the construction of tombs requires a lot of glutinous rice, such as the imperial tomb of Emperor Shenzong, which was built by him, a master craftsman Chen.

That is, glutinous rice is mixed with lime, and neem leaves are added, and after mashing, it is wrapped layer by layer around the tomb and the coffin, and the top should be particularly thickened, so that the tomb can isolate the air, impermeable to water and crack.

Its hardness is very hard, and in addition, just like the palace wall of the Great Song Dynasty, of course, it is not the kind of yellow mud piled through, but wrapped in a layer of masonry outside, and between the masonry and stone, it is the porridge used mixed with lime to imprison.

But in this way, the cost is really high. But now, the Yuanyou cement that Wang Yang made out is really speechless.
