Chapter 756 The more I think about it, the more something seems wrong

After laughing, Wang Dazhu led a group of people to start unloading the truck, while Wang An led Wang Shuai and Wu Dong into the house.

After brewing a cup of tea for each of them and lighting a cigarette for each of them, Wang An sat on a stool on the floor of the east room.

Then, Wang An asked with a smile:
"Brothers, what's going on? Why did you give me so much cement? It must be more than 10 tons."

Wu Dong smiled and said:

"Yes, a full 15 tons. I thought this stuff has to be mixed in proportion, one ton of cement and two and a half tons of sand is just right. Then I made you 30 cubic meters of sand. Haha, how about that? Brothers, you are so nice not to give it to me?"

I have to say, the cars of this era are really awesome. A car with a standard load capacity of 5 tons can actually pull 15 tons!
This is normal. After all, a single-cylinder 12-horsepower walk-behind tractor can pull 4 tons of cement.

In fact, the cement grade of this era is relatively high, so the best ratio of cement to sand is 1 to 3.

If you are building a house and laying bricks normally, 1:4 or even 1:5 is completely sufficient.

When Wang An heard this, he immediately shouted exaggeratedly:
"That's really very kind of you, hahahaha. Then I will add a few more layers of cement mortar under the walls of these two houses, hahahaha."

Wang An's original plan was to build the foundation with stones and cement, and then pour a circle of bottom beams with cement. As for the main wall above the bottom beam, he could just use black soil and mud to build bricks.

After the main wall is built and the beams are constructed, two layers of bricks are laid with cement and sand. As for the last two front and rear horizontal beams, they are cast with cement and steel bars.

Finally, after the house is roofed, that is, after it is basically built, the outer walls can be grouted with cement and fine sand.

Simply put, the places in the entire house that require the most cement are the foundation, the ring beam underneath, the two front and rear horizontal beams above, and the wall joints.

The main wall, which required the most cement, was replaced with black soil mud.

If Wang An's original plan was followed, about six or seven tons of cement would be enough for each house.

Because Wang An’s previous idea was to build a 37-meter wall, which means a wall as thick as the length of a brick plus the width of a brick.

After all, the floor of the house is a fire dragon, the sleeping place is a kang, and the north wall is a hollow fire wall.

With these three heating methods combined, the temperature in the room is theoretically absolutely sufficient.

However, Comrade Liu Guilan was strongly dissatisfied with this. In her words:
"You must be crazy to buy so many bricks and not make the wall thicker!"

So, the wall of 37 becomes 50!
That is, a wall that is the length of 2 bricks, or the width of 4 bricks thick.

Of course, this doesn’t matter to Wang An. It’s just a matter of using more bricks, which is a small matter.

Although the amount of cement will increase, it will only be enough to increase by one or two tons.

Fortunately, the 50-meter-high wall is made of bricks made of mud, and even without any mud, it is still very high and there is no fuss at all. With the shelves and tiles on the roof pressing down, it is quite solid.

So, although walls built with cement and sand are the strongest and most solid, there is really no need to say anything about it.

Besides, the method of building walls with mud and filling the joints with cement on the outside has been effectively verified in later generations, which means that such walls are strong enough.

When Wang Shuai heard what Wang An said, his expression was obviously startled, and then he frowned slightly and said:

"What's up, Xiao An? From what you said, you are planning to use soil to build bricks?"

Wang An said with a smile:

"Well, my mother insisted on building a 50-meter wall. Mud is enough, it's very strong." After Wang An finished speaking, Wang Shuai pondered and said:

"If we use cement and sand to build a wall, how much cement will be needed?"

Wang An frowned and said:

"I haven't really calculated this in detail. Anyway, my house is 20 meters long and 10 meters wide, and the wall is 3 meters high."

After a pause, mainly to recall the data he had seen in his previous life, Wang An continued:

"If we calculate it by square meter, a 50-square-meter wall would require about 1 kilograms of cement and 140 kilograms of sand."

"If you add up the four walls and the gable, it would be about 200 square meters! If you remove the windows and doors."

At this point, Wang An subconsciously wanted to reach into his pocket to find the blueprint, because the sizes of the windows and doors were marked on the blueprint.

But Wang An suddenly remembered that the blueprint had been taken away by his father and those craftsmen for study.

So, Wang An muttered:
"The front window is 3 meters long and 1.8 meters high, a total of four windows, the rear window is 1.8 meters long and 1.6 meters high, also four windows, and there are doors. The front door is 2 meters high and 3.2 meters wide, and the rear door is also 2 meters high and 1.2 meters wide."

After saying this, Wang An pondered for a long time before saying:
"All together, it's about 40 square meters. As for the wall, it's about 160 square meters."

After Wang An finished speaking, Wang Shuai started to draw numbers on the kang. Before Wang An could figure it out, Wang Shuai said:
"Just to build the wall, we need 11200 kilograms of cement, which is 12 tons."

Wang An thought for a moment and said:
"Yeah, we need 12 tons of cement and about 40 tons of sand. If one cubic meter of sand weighs 1.4 tons, then we need about 30 cubic meters of sand."

Wu Dong blinked and said:

"If it's 12 tons of cement, it won't cost that much."

Wang Shuai also suddenly realized and said:

"Yeah, 180 yuan per ton, that's only about 2200 yuan. Come on, Xiao An, don't worry about it. I'll have them deliver it to you tomorrow."

When Wu Dong heard this, he felt more and more that something was wrong.

Wang An was in the same state at this time.

Wang An and Wu Dong looked at each other, and then Wu Dong said with a look of sudden realization:
"Xiao Shuai, that's not right. We were calculating for one house just now. Didn't Xiao An say he wanted to build two?"

However, the more Wang An thought about it, the more he felt something was wrong. It was about the price of cement.

So after Wu Dong finished speaking, Wang An said with a surprised look on his face:

"Wait a minute, you bought this cement for 180 per ton?"

Wu Dong and Wang Shuai blinked at the same time, and then Wang Shuai said as a matter of course:
"Well, isn't this the price of this stuff?"

Wu Dong also asked in bewilderment:

"What do you mean, Xiao An? Wasn't the cement you bought two days ago priced at this price?"

After the two men finished speaking, Wang An stared blankly for a long time, then suddenly started cursing:
"Fuck him, Bai Zhihong, that lazy bastard, sold it to me for 210 a ton. I even had a fight with him for that price. Fuck him!"
