Chapter 290

PS: no state today, only 2000, 3:30 Forgive me, gentlemen.

"Come on, put the ash in it." Keller slowly leads a student to mix plant ash into lime.

Lime, a kind of East-West red leaf ridge, has been used all the time to keep the road clean and dry. The English islands are rainy and sunny all the year round. After frequent rain, the ground is muddy, which brings great trouble to the transportation industry.

But since lime was mixed into the sand and gravel, Camero's road began to be strong, and the hooves of horses and oxen were extremely comfortable to run on. However, Keller knew that this was not cement, but only the solidification caused by lime absorbing the moisture in the land. If the moisture content exceeded the amount that lime could absorb, it would overflow. Although this simple way made Camelot's road easy to walk, he knew that these roads would only be roads in the future, and roads with lime would not be allowed Can be turned into fields again.

But he needs better materials.

There is no better material than cement.

However, in terms of current technology, Keller lacks a chemical of inorganic cementitious materials. The development of this kind of thing is very difficult in terms of current technology, but quicklime is not necessarily.

Raw limestone made by adding plant ash and heating it with limestone.

Now it's the last step, stirring.

Keller first searched for limestone for a long time. Before that, all that was put in the land was lime powder, not real quicklime.

Before that, there was a classification of the processing of charcoal and charcoal, and recently Kailar just built a charcoal distillation plant, and the production of quicklime has been delayed until now.

In fact, the ancient Chinese had a method of making quicklime. After laying limestone and wood in layers and burning it for a week (uninterrupted), pure quicklime powder could be obtained. However, Keller came from modern times, and did not know such a strange knowledge, so he could only solve it with the stupid methods of modern people.

After the charcoal was made, it brought the internal combustion temperature of more than 700 degrees, but Kailar naturally had a way to make it burn more thoroughly, that is, the blast furnace and the bellows.

Blast furnace is to let charcoal combustion temperature polymerization, and the bellows is to transport oxygen to help charcoal combustion more fully.

In this way, the temperature in the furnace is close to the water in the big pot. The water starts to boil and evaporate in an instant. Because of Keller's explanation, no one dares to put his face in the steam, because the temperature of the steam alone reaches the point of scalding.

However, what is not afraid of is that there is a pump pump pump sealed with gum, which is constantly adding water under the tireless input of the two Kailar disciples.

To tell you the truth, this is just an experiment, whether the wet steam lime can succeed.

Two hours later, after drinking ten pots of black tea, Keller opened the lid and got the message - failed!

Well, isn't Keller disappointed.

With just another wave, a small mound of earth was raised.

This is a kiln. It can be used to burn charcoal or lime. Kailar's charcoal production technology is gradually mature, but Carboniferous is still an arduous mining work. Although there are a lot of coal now, most of them are charcoal, which is very valuable.

Kailar is still storing coal for future use as honeycomb coal, although the reserves are insufficient and the stamping process is not mature.

Britain is such a wet place that it rains all the time, and it is often attacked by monsoon or hail. The heavy snow is like an aunt's regular visit every year.

Even if Kailar was in power, many people were frozen to death every year, and the appearance of honeycomb briquette could change everything.

Small energy and low consumption of honeycomb coal can almost enter thousands of households, so that people and ordinary soldiers can save a lot of time.

The premise is that a small heater can be held in hand, and a small heater can save many lives.

Do you know what it feels like to be frozen off your fingers on patrol at night?

Camero has no cotton, and is not suitable for planting cotton. The so-called gloves are only able to protect their hands from freezing on the barrel of a gun. Ordinary militia forces are just wooden poles, but elite troops are all iron spears. The iron spears in winter bring about the possibility that their hands will stick to them and tear them to pieces. Before King Uther's rise to the occupation and glory of knighthood No one wants to be a soldier.

Because there are not so many soldiers who freeze to death every winter in this cold and bitter land of Camero.

Just think about it. It's just two layers of metal armor , a pair of cloth gloves with a long iron gun.

A lot of people are directly frozen to death! The temperature of iron armour is much colder than that of ice, and the spear makes the blood of fingers not circulate. Many soldiers take off their gloves and even take their fingers out before they have a fire.

It's not a joke! It is the real, poor material conditions of the ancient life.

Every cold current may damage a family, every winter there are countless families broken and killed!

Kailar is changing all this, perhaps for a short time, but he is changing. Now every red leaf ridge and Camelot family has a charcoal fire stove, enough for them to sleep until dawn. Now the textile industry of Camelot brings huge export volume, and in return is a large amount of fur. These thick and comfortable fur are made in large quantities They were sold as winter clothes and gloves, and the profits after the sale were purchased and sold again.In order to turn a small country into a big energy, Camero adopted a dictatorship system, including the largest landowner, the largest businessman and monopolistic trade. As a result, 30% of the money generated was used by the royal family as military expenditure, 30% as research cost, and the remaining 40% was put into the pillar of people's livelihood.

The so-called support for the people does not mean the free distribution of gold coins - it will only lead to the rapid depreciation of gold coins and the rise of prices.

It includes improving the welfare of knights and soldiers, and employing retired disabled veterans as grassroots.

Or paying shipyards to build warships, or hiring ordinary people to mine or sun salt.

To put it bluntly, as the royal family is almost the largest capitalist, and the nationals of this country are the Royal servants, and the soldiers are his bodyguards.

Although it's a bit of a jerk, Camero's model is exactly like this.

It was a success to burn lime in caves. Large quantities of lime are burned, and quicklime is added to water and mixed with clay in a ratio of three to one, then sand and gravel are added.

The mixing work was handed over to several strong disciples. Finally, the cement was put into a huge iron column. In the iron column, there was an iron bar of the same length as the iron column. The iron column was a removable fixed shell. After five days, this was the earliest reinforced concrete.

This invention is enough to change the whole continent! (to be continued. If you like this work, you are welcome to start（ qidian.com ）Your support is my biggest motivation to vote for recommendation and monthly tickets. )
