Chapter 211 Bamboo Reinforced Concrete

The corresponding method is to do material treatment on bamboo tendons. The chemical plant in Bopu is already capable of producing wood tar and coal tar.These two products are quite old in the chemical industry.

Using a simple fractionation device, many different chemical products can be fractionated from it.These days, due to the needs of steelmaking, the metallurgical department is coking in Bopu, and a considerable amount of coal tar has been accumulated. In addition to being made into tar bombs by chemical plants and smeared on utility poles along the road, these black and dirty coal tars It was used for anti-corrosion during shipbuilding.There are still many left in clay pots.In addition to coal tar, chemical plants also receive wood tar produced when a large number of wood processing plants process charcoal.It was piled up everywhere in the temporary warehouse.

Because the fractionation tower has not been installed yet, and the fractionated products need to be cleaned with acid and alkali, Ji Situi can’t deal with them for a while, but so many things are piled up in the shed, not to mention the smell they emit, and they have to find someone to guard them ——Whether it's the locals or the people who travel through the world, there are people who are thinking about these things.The idea of ​​the natives is better. Basically, they are preparing to use it as fuel or waterproof the boat. The traversers have their own whimsy and whimsy. Some dangerous things made by half-assed chemical industry can make Ji Si retreat into a cold sweat. Come.

Hearing Mei Wan's request for help, Ji Situi expressed his great welcome - it's better if someone uses it than Mei has no one.Coal tar, the most primitive anti-corrosion material, is more than enough to deal with bamboo tendons.

Mei Wan firstly soaked the opened bamboo tendons in wood tar. This process is not only for coating the tar, but Mei Wan also hopes that through this method, the dried bamboo tendons can absorb the creosote in the wood tar, making the material It no longer absorbs water, and has a unique anti-corrosion and insect-proof effect.

After soaking for a few days, make sure that the bamboo tendons are completely soaked, take them out, and then evenly coat the surface with coal tar—of course, if it is modern time and space, the processing method is much more complicated, and the chemical ability of the traverser is still relatively high. Limited, only the simplest process can be used.

After the treatment is completed, the bamboo rebar itself needs to be physically improved to be suitable as a raw material for bamboo rebar concrete.One disadvantage of bamboo is that the surface is too smooth, not only difficult to fix when binding bamboo tendons, but also easy to move and bubble when the concrete is bonded.The method adopted is to adapt the shape of the bamboo itself and open gaps in the bamboo material.The other is the method of winding iron wire around bamboo tendons.

Fortunately, although the steel reserves in the hands of the Ministry of Metallurgy cannot supply steel bars, there is still more than enough supply of 18-gauge iron wire.It is very convenient to process iron wire. Add wrought iron bars to the steel template, and use power machinery to pull and stretch for many times.The process is extremely simple, and the raw materials are not consumed much.I heard that the construction company wanted to trial-produce prefabricated bamboo-reinforced concrete slabs. The Ministry of Metallurgy immediately expressed its strong support and agreed to supply as much iron wire as possible—anyway, recently, various departments need iron wire: Lingao Telecom needs to lay telephone lines, and the Ministry of Light Industry needs to put into production sewing clothes. Needle.

All the construction engineering companies have devoted themselves to the work of binding steel bars.This job has a certain technical content, if Mei Wan didn't come from a construction site, she would really be a little unsure.What's more, it's not a steel bar, but a smooth bamboo bar.A few people took several construction workers who are commonly used in construction companies, and wrapped bamboo sheets around and around.The only references are a few blurry pictures printed out by the four.Several traversers had never done this job before, and some people saw blood on their hands after a while, and they were gloriously injured.

"God, this is more difficult than steel bars." Yan Quezhi complained.

Bingfeng nodded: "This thing saves time and energy, and its strength is also discounted. If it really blows so well, why not promote it."

Mei Wan also felt a little regretful at this time, but it was inconvenient to express it: "Now we have to solve the problem of having or not. We even mix the concrete by ourselves, so we just need to call the commercial concrete company to bring a few tankers?"

The first prefabricated slab was tested after three days of curing, which proved that it can be used as a light floor slab. This result is quite encouraging.

"However, believe it or not, it's better not to make this thing a load-bearing piece." Bingfeng was still a little worried.

That being said, this kind of substitute will be put into production immediately——Bairen City is setting off a new wave of construction, and houses are being built everywhere. The availability of prefabricated concrete is a huge benefit for construction companies Convenience.Mei Wan immediately conducted a comprehensive training for the indigenous construction workers in the company, teaching them to tie steel bars and make prefabricated panels.Soon, the first batch of cement slabs were put into the construction of the "new countryside" and the stadium.

The entire project progressed quickly due to the use of machinery used.After all, an hour of earthwork for an excavator requires dozens of workers to work for a day.As for the rammed earth work, Mei Wan also used the mode of roller compaction and manual rammed earth to go hand in hand, and worked overnight.At night, more than a dozen gas lamps and countless torch cages were lit to illuminate the construction site.All the staff are divided into two shifts, regardless of day or night, and the machine is rumbling day and night on the construction site, and the voices of people are full of people.

"This project really has the atmosphere of a big battle." Bingfeng had just finished presiding over a section of the project, and dragged his tired body back to the shade shed of the project headquarters. The temperature outside is still below 10°C, but he only wears a pair of clothes. A T-shirt full of dust and dirt, because I have only slept for four or five hours a day for three or four consecutive days, and my eyes are red.

"Drink some Wanglaoji." Yan Quezhi brought over a big plastic bottle, which was filled with withered grass tea made by Nanhai himself. The crew is working.

"I'd rather drink cold water than drink this thing." Bingfeng trembled when he smelled the withered grass tea. This thing is no better than canned tea from another time and space. Weird, but acceptable.

Bingfeng poured the light saline solution specially prepared by the Ministry of Health into his stomach, and wiped his sweat with a towel, before he let out a long breath:

"I really want to drink Coke in my dreams." He lamented, the little enjoyment of another time and space is now out of reach.Sometimes he really regretted why he came here.Isn't this the same as in the past - no, it's worse than the past, at least drink as much Coke as you want at that time.

"When a section is finished, seal the section with stones and don't wait for the other section." Mei Wan was instructing on the construction site every day, her eyes were red and her voice was hoarse.

"President Mei is really desperate." Bingfeng said to Zhuo Tianmin.The latter didn't answer, with a sad face - he hasn't been home for three days. Although his son was entrusted to Wu De's woman to see, he always felt uneasy.

Yan Quezhi said: "I don't understand, why is the governor so anxious for this thing? Do you need it right now?"

"Parade, man."

"parade?"

"Yes, show it to the natives who came to the meeting. Show power." Bingfeng is busy finishing the project of the army club recently, knowing that the army has been practicing queues after the year.

"It's a waste of money for the people, and it's a waste of money for the people." Yan Quezhi didn't take it seriously. "I don't think it's more important to expand the capacity of the hydropower station? For the cost of building such a grand viewing platform, two large dams on the Wenlan River are enough."

"You don't know how much the executive committee invested in this time." Bingfeng took out a cigarette from his pocket, "Come here."

"Why, you still have cigarettes in your hand?" Yan Quezhi took it from him, and found that it was a hand-rolled cigarette. The rough paper could be seen as a local product, and the tobacco leaves inside were golden.

"This is the tobacco that a foreign trade company got from Macau. I got some and rolled it myself."

"I think this thing was built to satisfy the leadership desires of the leaders of the executive committee, right? Ma Qianzhu might hold back his strength and want to shout those few times, 'Hello, comrades, you have worked hard, comrades'."

"Don't wrong Ma Gong here. If you want to shout, it's not his turn. Mr. Wen is the chairman of the executive committee. The most Ma Gong shouts is 'please review'—isn't he the chief of the general staff?"

"I think they are quite united in this matter."

The two were puffing and puffing. To be honest, the taste of the tobacco was very different from that of cigarettes—it was sun-dried tobacco, not the flue-cured tobacco commonly used in modern cigarettes. With the rough rolling paper, it could only be regarded as better than nothing.

"The foreign trade company has a special supply, where did you get it? You can't sell it in the cafeteria."

"Do you rely on the mountains to eat the mountains?" Bingfeng pouted, "This is military tobacco distributed to the army. Aren't we helping the army to build a club recently? I was in command on the construction site, so I gave a lot of it to me."

"You kid is corrupt—"

"The army is poor, and the navy is the best." Bingfeng exhaled enviously, coughed twice, "If it wasn't for my seasickness, I would have joined the navy too. I lived a happy life—"

"We are suffering from engineering," Yan Quezhi looked at Mei Lin, who was sweating profusely on the construction site, directing the workers to lay stones, and Li Xiaolu, who was holding a level to measure the level, and other people. "Even women are working on the construction site."

"Are you quite good at pity and cherish jade? Why, interesting?"

"Where," Yan Quezhi hurriedly dismissed, "She doesn't say a word except for work all day long, and she looks like a man owes her 500 million. I think it's interesting or boring."

"That's right." Bingfeng said, "We have to train some people, at least builders, technicians, etc., so that we don't have to go to the construction site all day long."

"Didn't it mean that a school would be built after the conference? We also applied to open a major in the school: the Department of Civil Engineering."

"I don't need any construction workers. It's okay to have a secretary first. It's a bonus to squeeze my shoulders and legs after work."

"Hehe, there are less than 40 girls graduating from the nursing school, so it's our turn?"

"Yeah, Mr. Mei might have one of them."
