Chapter 1815 Asbestos fiber cement board
In recent years, although England has not improved much under the governance of Edward, it is still relatively stable. The population that had been lost due to war has gradually recovered.
However, these populations are still too small. Unfortunately, England is not Marin's now, and Marin cannot vigorously promote and encourage childbirth in England. So, even if you have any ideas, you can only wait and talk about it later.
Of course, in Northumberland and Isle of Wight under Marin, he could still encourage childbirth. Even in Scotland's border counties and Highland counties, Marin adopted the method of encouraging childbirth.
Because the output of Beihai fishing farms is increasing, Marin has now ordered that in the areas under his rule, whether it is his own manor or other people's manor, all subsidies will be given as long as there are pregnant women. Of course, the subsidy is not money, but salted fish. If conditions permit, Marin will also encourage the soup of fresh meat in the manor and give priority to pregnant women.
Not only that, Marin also ordered that he ruled the manor himself, and once a woman is pregnant, she could stop working and take "pregnancy leave". However, the benefits are not at all, and it is even better than ordinary people. In short, pregnant women are preferred.
Even in every town, Malin will set up maternity hospitals to take care of pregnant women. In addition, maternity hospitals will have female doctors who have received training in the lateral resection technology of natural delivery and know how to use forceps as the main delivery staff to ensure the safety of delivery.
These technologies were all studied by Marin in order to ensure the safety of Angela's birth when she gave birth to William. Now, they are just used to ensure the safety of mothers in the country during childbirth. Of course, these obstetrics and gynecology hospitals are now all assigned to Marin's "Save the Knights" name, becoming legal medical units recognized by the church, and enjoying the church's subsidy sponsorship.
In addition, Marin also ordered that when taking the bus, everyone needs to give up their seats to pregnant women. In addition, beating pregnant women is strictly prohibited. If beating pregnant women causes miscarriage, they will be severely punished. Because this is equivalent to murdering a new life.
...
Speaking of the buses in Beihai Country, we have to mention the current public transportation construction in Beihai Country. Before, Malin had been planning to build cement roads. However, he had always been worried that the cement roads were too eye-catching and attracted attention. Therefore, when two main roads of two cement roads across the north and south and east and west were built locally, he deliberately applied other things to the surface of the road to cover the original appearance of the road, and cut the cement roads into pieces to make them look like large stone slabs spliced together.
But later, after Marin thought of the cement board road, he let go of his concerns. Then, he started the "infrastructure madman" model in Beihai Country.
To this end, Marin ordered the cement plant in Konabrook, west of Newfoundland to take advantage of the local limestone mines and combine the coal sent by coal ships from Cape Breton Island to expand cement production.
Then, on the local East Friesian Islands, Marin also ordered the restoration of abandoned cement plants on Baltrum Island and the adjacent Langeog Island, and expanded the scale to be specially used for the production of cement.
The cement production here originally came from sea transportation. For example, limestone, clay and fluorite were all wholesale from the Hamburg and Bremen markets. The coal for burning cement was transported from the Newcastle coal mine opposite the sea, which was very convenient and low in cost.
Then, Marin also built a large-scale brick factory and cement board factory near the steel plant in Krumhein to produce bricks and cement boards. Steel smelting will produce a large amount of slag, which is very suitable for firing cement and can also make bricks.
Of course, building brick factories and cement board factories next to the steel plant was not to directly utilize steel slag, but to use the dock facilities near Krumhein to facilitate the transport of cement. After all, in order to run this steel plant, Marin built a special dock in the local area to facilitate the transportation of ore and coal. At the same time, a large number of soldiers were also stationed to ensure local safety.
The cement board factory will definitely attract world attention in the future, after all, it is the top material for paving. Therefore, it is necessary to have a place that is convenient for transportation and is not afraid of the enemy's covetousness and spying. Obviously, the Krumhein Steel Plant with a high level of security protection is a good choice. Moreover, setting up a factory here is also conducive to centralized industrial management and rational use of local infrastructure resources.
At present, the cement board factory in Krumhein mainly produces two specifications of cement boards - the ordinary type of 240mmx240mmx53mm and the thickened type of 240mmx240mmx26mm.
Among them, ordinary cement tiles are mainly used for road paving on main roads. Their thickness is similar to that of later red bricks, and their strength is sufficient, and they can withstand the passage of heavy-loaded carriages.
The thickness reduction type with half thickness is found by the cement board factory craftsmen who found that when laying non-main roads (that is, small streets and alleys) inside the city, ordinary cement boards with a thickness of 53mm are not needed, half of the thickness is enough. Because those small streets and alleys are often for pedestrians and rarely take heavy carriages. Therefore, half the thickness of cement board bricks is definitely enough.
In addition, there are not many rural roads, and this type of thickened cement tiles are enough. Moreover, after the thickness is halved, the cement material will also be saved by half, which will save paving costs more.
After thinking about it, Malin agreed with the craftsmen and rewarded the craftsmen who proposed thickened cement tiles. Because this indeed saved him half of the cost of road construction materials. Moreover, those small streets and alleys and secluded villages do not need to use such solid cement tiles. After the thickness is reduced by half, the same material can pave one more road.
Stimulated by this reward, later, when making cement tiles, the craftsmen proposed the idea of adding asbestos fibers and made asbestos fiber cement tiles with good strength. After testing, the cement tiles with asbestos fibers added were of far quality than ordinary cement tiles.
This chapter is not over, please click on the next page to continue reading! Kaur, a craftsman who proposed this method of cement brick making, participated in the process of helping the Swiss build defenses. At that time, Marin asked these craftsmen to lead a large number of cement to go south, and even asked someone to purchase a large amount of asbestos fiber in Switzerland, saying that it was used for fiber concrete manufacturing, which could increase the strength of the fortifications.
During construction, Kaul remembered the concept of "fiber concrete" proposed by Marin and found that asbestos fiber concrete is indeed stronger than ordinary concrete.
This time he was transferred to the cement board factory. When he was making the cement board, he remembered that if asbestos fiber is added inside the cement board, can the cement board be stronger? Then, the results showed that his guess was correct...
After seeing the samples presented by the cement slab factory, a word appeared in Marin's mind - asbestos tiles...
In later generations, asbestos tiles were a very ordinary large tiles, which were an important raw material for building a house. Their material was made of asbestos fibers (or glass fibers) added to cement. Even many of the car brake pads in later generations were mixed with asbestos fibers.
However, before traveling, Marin seemed to remember that when the brake pads of the car were rubbing, they would produce asbestos dust due to friction. If these asbestos dust were inhaled into the lungs, it could lead to lung disease and even lung cancer.
Of course, this statement is a little exaggerated. However, Marin knew that it is inevitable that a large amount of asbestos dust will be produced during the production of asbestos tiles. If asbestos tiles are manufactured for a long time and lack safety protection, there will definitely be big problems.
However, there is no harm after being made of asbestos tiles. Because asbestos dust is not sucked into the lungs, it is difficult to cause harm.
By the same token, cement bricks made of asbestos fiber are not harmful to the finished product. After all, this is just a road material, and people will not deliberately grind and inhale asbestos dust on the ground, so there is basically no harm.
Asbestos fiber itself is low in cost, and the German region is an important production area of asbestos. In addition, Egypt, Greece, and Italy are all asbestos production areas of traditional Chinese medicine. Because of its large production volume and not very wide use, asbestos is not expensive. The cost of using asbestos fiber cement boards is not high, but the quality is much improved.
