Chapter Ninety-Eight: Bamboo Reinforced Concrete

For personal reasons, the speed of the recent codeword is not guaranteed...... I can also do the number of words in the water, 10,000 words a day on the water, but it doesn't make sense to be disrespectful to the book friends who read the text - so, I'm sorry, on the premise of ensuring that it is constantly updated and not too supervised, it may only be a single update from tomorrow for the time being, and the time will not be too long.

In May, the summer tax was to be levied according to the usual practice, and at this time in previous years, Lingao County ordered Wu Mingjin to have a headache. The annual summer tax and autumn grain are the difficulties he has to face, because he can't collect the full amount every year, and there are arrears every year, although there are many reasons why he can't be promoted, but this is one of the important reasons.

Since being placed under house arrest by Xia Nan in disguise, he has been at a loss for a while, not knowing what to do. According to the integrity of a civil official, if he fell into the hands of thieves, he should make his own decision, but he was unwilling, because although Xia Nan was ill-intentioned and domineering, he did not openly rebel, and Lingao County was still the Lingao County of the Ming Dynasty.

After thinking about it, he still decided to wait, as for whether to wait for the summer south rebellion or wait for a miracle to happen, he himself couldn't say.

When it came to the summer tax season, Wu Da County, which should have been a headache, was much more comfortable than in previous years. Anyway, I couldn't collect the taxes even if I tried to collect them, and now that I have lost my personal freedom, I have found a reason for myself to hide in the county government with peace of mind.

Although he was under house arrest, it did not prevent him from learning about the outside world. The Li people made a rebellion, and he also heard of the killing of big households, needless to say, it was Xia Nan's handiwork, and it was a trick to push Huang Mengjia to the front of the stage to attract hatred, and he had already used it once to attack the county.

It's just that what I didn't expect was that after Xia Nan became the largest landlord in Lingao, he actually offered to pay taxes to the county government.

Lingao County has to collect 7,000 stone of grain for summer tax, 8,000 stone for autumn grain, and 8,000 taels of Liao salary for the whole year. This is only the positive amount, as well as the various expenses of grain collection and transportation, not counting the benefits of the handling personnel, how to pay the Guangxia tax is nearly 10,000 stone brown rice, which is equivalent to more than 10,000 taels of silver.

Of course, this is only an ideal number, and the real situation is that the summer tax can collect two or three thousand stone brown rice every year, thank God. The total amount of land deeds changed by Nan in the county was more than 1,000 mu, and he was willing to pay 1,500 taels of silver -- of course, this was not a sufficient amount.

1,500 taels of cash, whether it is exchanged for a part of brown rice or directly paid for discounted silver, plus retail investors can collect some grain, the two are together, and they actually exceed the average level of previous years.

Wu Mingjin is a little incomprehensible to Xia Nan, no matter how you look at it, he has the potential to be a thief, how can he take the initiative to pay taxes? However, this result objectively helped him, and most of the task of summer tax was completed without much effort, according to the unspoken rules of officialdom, this has been basically completed, because everyone knows that it is impossible to complete the task in full, and tax arrears are a phenomenon everywhere.

Thinking that he would not have to deal with the tricks of the local officials who deceived and concealed the households, nor did he have to face the endless refusal and omission of the landlords and gentry, he would be able to get through the difficulties of the summer tax, Wu Mingjin suddenly felt that Xia Nan also had a cute side.

Xia Nan didn't know what Wu Daxian Ling thought, he only knew that he had made up for his last shortcoming, and he could let go of his hands and feet to show his skills. In this summer tax, Tan Shan and others collected more than 3,000 stones of grain, which initially solved the grain problem. As for the initiative to pay taxes, it is because the government is needed to stabilize people's hearts for the time being, and Xia Nan does not want to overthrow all the old order too radically.

In May of the fourth year of Chongzhen, the training ground of Mayuan Village, which had been quiet for a while, began to be lively again, and the Li native soldiers who were sent out to complete unspeakable tasks returned to the team and continued to train under the leadership of the escort team.

Now that the center of gravity of Xia Nan has begun to tilt towards the escort team, and other matters are on the right track, it is time to grasp the construction of the team, and it is an unbreakable truth that power comes out of the barrel of a gun.

Xia Nan's fighters are divided into two parts: one is the core force - the escort composed of 300 young men from Ma Yuan Village, who are the most loyal to Xia Nan and have the strongest combat effectiveness, and they are currently the only ones who have been issued with Qionghai rifles; The second is that Huang Mengjia's 300 native soldiers beheaded the mountain, and after losing three battles in a row at the hands of the old guards, they were completely subdued, with strong hand-to-hand combat ability and very rich combat experience.

If you want to do a good job, you must first sharpen your tools. The native soldiers are of different nationalities from the Han guards, and their living habits are also different, and they leave the familiar living environment and come to the place of the Han people, and there will always be a pimple in their hearts after a long time. In order to give the soldiers a sense of belonging, Xia Nan decided to start by improving the living environment and living conditions.

The renovation of the training ground, which had been planned for a long time but had been delayed, was officially launched. Because there were too many things to do before, whether it was the development of iron mines, the manufacture of guns and artillery, or the seizure of land, it was a problem that had to be solved immediately, and then several small-scale battles were launched, and the planned project was put on hold.

The reconstructed training ground is the first official use of Lin Weiye's improved cement. Since the first kiln cement was fired with limestone and clay, Lin Weiye felt that there was still room for improvement, and it was not officially put into use, after the development of Tiandu Iron Mine began to smelt pig iron, the slag produced by ironmaking was mixed into the original material, and the cement produced was very close to the modern standard of cement, and after cooling, in the words of the cement kiln workers, it was "like stone from afar, hard as iron".

Cement alone is not enough, Lin Weiye tried to use bamboo reinforcement instead of steel bars, and built houses with bamboo reinforcement concrete. The compressive strength of the cement itself is good, but the tensile strength is low. Mixed with sand and gravel to mix into the original concrete, adding bamboo bars, can greatly improve the tensile strength, such a structure is a bit close to modern reinforced concrete. If the attempt is successful, not only the training ground, but also other houses and docks in other places can be promoted in the future.

Xia Nan handed over the task of infrastructure construction to Tan Er, anyway, this task does not require any advanced knowledge, and it is just a Ming Dynasty version of the contract foreman. Lin Weiye instructed Tan Er on the spot, let him master the whole process, and he could hand it over to him in the future.

In fact, the process is very simple, that is, cement is used as cementitious material, sand and stone are added, mixed with water and stirred, and then poured into a hollow mold made with wooden boards in advance, and a few bamboo tendons are fixed in the middle, and the wooden boards are removed after condensation and hardening. As for the production of bamboo tendons, the bamboo is cut into strips, the bamboo is retained, and the simple anti-corrosion treatment is on the line, and if you pay attention to the point, you can score on the surface of the bamboo tendons to increase the adhesion of cement.

In terms of longitudinal tensile strength alone, bamboo is 5 times that of medium carbon steel. The mixed structural system composed of bamboo-reinforced concrete beams, columns, slabs and other components, and the walls are made of red bricks, so that the building is far more solid than the brick and wood mixed buildings of this time and space, let alone all-wood buildings, and the construction process is simpler, faster and cheaper.

Of course, this is not the only advantage, with the use of bamboo-reinforced concrete, the building can be developed to a higher level. However, the building of this brick-concrete structure cannot theoretically exceed 7 floors, because the load-bearing member is still the wall, and the force transmission mode is that the floor slab transmits force to the wall, and the wall transmits the force to the foundation in the form of line load. No matter how high it is, it can only develop the framework structure.
