Just as the Ministry of Rites and Guozijian were intensively preparing for the Ding Chou Branch Examination and the Palace Examination, the Ministry of Industry came with good news that the cement samples were made! However, none of them can use it, so they still have to ask the emperor to teach them how to use this thing.

This cement is not something that can be done, at least in a day or two, Zhu Cijiong naturally can't go to Xicheng District to show them on the spot, so they can only ask them to prepare the cement, the sand and gravel to be used, and all the tools and equipment to be used, and pull them to the palace in a car.

When Bi Maokang respectfully invited them to the square outside the Qianqing Palace, he couldn't cry or laugh, this cement packaging is too outrageous. The sand and gravel are still normal, they are all packed in burlap bags, and the wooden planks are only neatly stacked there, and the tools such as the size of the trowel are already a bit exaggerated, and they are even more exaggerated to make a special wooden frame and hang them like hanging weapons, and this cement is even more exaggerated, it is actually packed with a treasure chest containing gold and silver jewelry!

Well, cement is indeed a rarity in this era, but you don't need to pack the whole treasure chest, the amount of cement is calculated in tons, sell dozens of pounds of cement to send a treasure chest, then you have to pay for the pants you don't have to wear!

Zhu Cijiong pointed to the treasure chests with a smile and said: "Meng Hou, don't use such expensive treasure chests for cement, after all, the output of cement will be sold to the common people after all, you also know the cost of this cement, it is not worth any money at all, plus the amount is also large, it is too expensive to sell and no one will use it, this thing still depends on the amount to make money, you can't lose money if you pack it like this, a box of cement is not as expensive as this treasure chest!" “

When Bi Maokang heard this, his old face turned red, and he replied embarrassedly: "The emperor forgives me, didn't you say that this cement packaging should be waterproof, Weichen couldn't find anything waterproof for a while, so he found a few treasure chests to hold it temporarily." “

Zhu Cijiong thought about it when he heard this, and casually instructed: "Of course, there are no ready-made things for packaging cement, you have to find someone to make them, do you know the oil umbrella?" Just use the kind of oil paper used to make a sack the size of a burlap bag, of course, the paper doesn't have to be so thick, and it doesn't have to be so beautiful, how cheap it is. “

Bi Maokang bowed his head in shame and said, "Weichen understands." “

Seeing him like this, Zhu Cijiong hurriedly comforted: "Okay, okay, I just said casually, those who don't know are not guilty, don't go to your heart, come, I will teach you how to use this cement." “

After that, he rolled up his sleeves and stayed up to get the shovel, Cao Huachun on the side hurriedly pulled his sleeve and persuaded in a low voice: "The emperor forgives the sins, let the minions below come to these things, you just guide and guide." “

Zhu Cijiong was stunned when he heard this, and then he realized that he was the emperor, he rolled down his sleeves in embarrassment, and said to the eunuch behind him: "You two go up, one of you takes a shovel and shovels cement and sand to the ground." “

When the two eunuchs heard this, they ran up quickly, picked up the shovel is a shovel, and soon there was a large pile on the ground, Zhu Cijiong instructed: "Well, it's almost, shovel a few more shovels of cement and sand, and then stir them together and stir them evenly." “

The two eunuchs were masters in the East Factory, so it was naturally easy to do this, they quickly shoveled a few shovels of cement and sand, and then snorted and stirred, Zhu Cijiong instructed them to stir again, and soon they stirred the three things evenly.

Zhu Cijiong instructed again: "Dig a pit in the middle, pour half a bucket of water into it, and stir evenly." “

The two eunuchs seemed to have the talent of plasterers, and Zhu Cijiong gave them a few rough instructions, and the movements were so standard that they couldn't do it, and soon they mixed the cement, sand, pebbles and water evenly.

Zhu Cijiong thought for a while, pointed to the stone slab on the ground and said, "Take a larger wooden board and put it on the ground, and then use a one-foot-wide wooden board to nail such a large frame on it, add a few supports on the outside, and nail it a little firmer." “

When the two eunuchs heard this, they looked at the size of the stone slab on the ground, and then took out the wooden board and nailed it in the open space on the side, perhaps because the Emperor of the Apocalypse was the carpenter emperor, the eunuchs in the palace were still doing carpentry work like that, and soon they nailed the wooden frame.

Zhu Cijiong stepped forward a few times, feeling almost solid enough, and then continued to command: "First pour some water to wet the inside of the wooden frame, and then shovel the mixed cement into it, and fill it a little higher than the frame." “

The two eunuchs immediately poured some water into the wooden frame, and then you shoveled it up quickly and quickly filled the wooden frame.

At this time, Zhu Cijiong pointed to the wooden frame next to him and said: "One person can take a big trowel to wipe it, wipe off the extra cement, and then wipe it as flat as the stone slab on the ground." “

When the two eunuchs heard this, they immediately took a big trowel and wiped it up awkwardly, Zhu Cijiong pointed out a few more words, and their movements slowly became standard, and soon the surface of the cement was as flat as a mirror.

Zhu Cijiong nodded with satisfaction on the side and said, "Well, yes, it's okay, tomorrow morning and afternoon, you both bring buckets of water over and pour them on it, be careful not to touch the cement." “

Bi Maokang stood aside and watched carefully, remembering it attentively, but as soon as he heard Zhu Cijiong's voice, he immediately became blindfolded, is this good!

He looked at Zhu Cijiong in disbelief, Zhu Cijiong waved his hand directly: "Okay, call it a day, you shovel the remaining cement paddle into the sack and throw it away, wash it on the ground, Meng Hou, you can see the results in two days." “

After that, he turned his hand around the back, turned around and went back to the palace, leaving Bi Maokang standing there, staring blankly at the cement paddle in the wooden frame.

It's just a cement, of course, it's that simple, two days later, Zhu Cijiong took him directly to the old place to check the test results.

Zhu Cijiong first stepped forward and touched the surface of the cement with his hand, it was hard and bare, without a little wool and sand, which proved that the cement had dried out, so he directly ordered the two eunuchs to remove the wooden planks on the four sides, and then stepped on it and stomped a few times.

Bi Maokang on the side was frightened and subconsciously stretched out his hands to help him, but Zhu Cijiong walked down casually and pretended to be forced: "I have said it, this cement will be as hard as a rock after it dries, I don't believe you can go up and try it." “

Bi Maokang was naturally a little unbelieving, he stomped a few feet with the guts, and sure enough, it was as hard as a rock, and his feet hurt from the shock, he bent down again to take a closer look, there was no trace on the cement surface, and now he finally believed it completely.

Zhu Cijiong patiently taught: "This is only the simplest use of cement, cement can also bond bricks and stones, as long as the gaps between bricks and stones are filled with cement mortar, they will be like a whole, as hard as rocks; Cement can also be used to build bridges, first with finger-thick steel bars to make a contour, and then fill with cement mortar, about three feet thick can bear the weight of the train; Cement can also be used to build high-rise buildings, first use steel and cement to pour load-bearing columns like this, and then fill them with bricks, it is no problem to build a building hundreds of meters high, of course, cement has other uses, according to the performance I just said, and so on, do you understand? “

If you don't understand this, it's an idiot, Bi Maokang hurriedly nodded and said: "Weichen understands, thank you for the emperor's teachings." “
