Chapter 661 Is this a crazy situation?

Although it only lasted one day, I still felt good after pressing it a few times. If I continued like this, I would be able to get hard in three days.

It's just that there are many gray-white particles in the dark gray cement, which will fall off with a gentle scrape.

Su Chen compared the off-white particles with the remaining gypsum and found that the two were the same.

In other words, although the gypsum was ground into powder and mixed with lime, after watering, the lime solidified, but the gypsum did not react at all.

"Is this a crazy situation? Su

Chen touched his forehead and thought to himself:"Hiss... It seems that gypsum is also divided into gypsum and plaster of paris. Is it because gypsum has not been burned like limestone?""

Su Chen did what he thought of, regenerated a pile of charcoal fire, and threw the gypsum into it. After a while, the off-white gypsum turned into powder.

Su Chen didn't expect that the gypsum was so unburned, so he immediately removed the burned gypsum. Come out and smash it lightly with a stone, and the gypsum will crack into several pieces. It is much easier to grind than the unburned gypsum before!

Crush the burned gypsum into powder, mix it with another portion of lime, add water and throw it away Add a few pebbles, mix them to make a lump of concrete, and place it next to yesterday's concrete for comparison later. After doing this, Su Chen takes everyone to see how the river sand is drying on the stones by the river, and then goes to the bamboo forest. Bring in all the bamboo that was not moved yesterday.

Su Chen is going to make the model of the hydraulic machine out of bamboo. After all, it is just a demonstration thing. In the end, whether it is strong and durable is not a consideration.

Invite a model from the elders Craftsman, help make the hydraulic machine.

There are few iron nails in Sujiazhai, and the general structure uses mortise and tenon joints. Although iron nails are not used, it is still strong and durable.

Su Chen just hopes that this craftsman can help him connect the bamboos to each other. The joint parts are all solved by this method of mortise and tenon.

In addition, after all, none of the young people are skilled in craftsmanship, so the work must be rough.

When the time comes to assemble, the parts will be different in size and crooked, making it difficult to assemble. Yes, that would be a joke.

The person who agreed to help Su Chen and the others make the hydraulic machine was an elderly grandfather in the Su family village. The old grandfather called Su Kaisheng. He was nearly seventy years old but energetic. He was always kind and kind-hearted, especially When they were children like Su Chen, they were always happy.

But you have to know that Grandpa Su Kaisheng was a famous warrior in Sujiazhai when he was young. He only learned the crafts later. He could do eighty tricks before. The heavy sword had a lot of blood on it!

Su Chen said that he wanted to build a water wheel first. Grandpa Su Kaisheng understood immediately. After asking about the size, he sawed several large bamboos into several pieces in just a few"swish"s. Ten sections.

The water wheel is not large in size, with the largest diameter only one and a half meters.

Use hard and strong old bamboo roots to make the shaft, use thinner bamboo tips to make the spokes, and fix sections of bamboo tubes around the spokes, like this A bamboo"wheel" is made.

Small bamboo rafts are fixed outside the bamboo tube to increase the thrust of water on the bamboo wheel. The main structure of the hydraulic machine, the water wheel, is completed!

Install some necessary small bamboo fixings. For example, the shaft and sleeve cannot move but can only rotate, and the shaft and sleeve are fixed with bamboo pins, etc.

It took almost a day to complete the water wheel.
