Lovely wife and cute baby oversized brand

Chapter 48
A group of people went to the roof of Building No. [-].

Cheng Yingxuan's QQ car is equipped with flat shoes. Before she got off the car, she had already replaced the high heels she usually wears with flat shoes.

The cracks in the swimming pool were observed on the top floor. The cracks were as wide and irregular as little fingers, and spread all over the swimming pool.

"Cheng Gong, look, how did the concrete cracks come about? What should we do now?" Liu Jin was a little anxious.

After Cheng Yingxuan looked around, she judged professionally, "There are many reasons for concrete cracks, such as structural deformation, uneven settlement, uncontrolled steel protection layer, and no structural reinforcement. These cracks can all be caused by the cracks in the swimming pool. It is a crack caused by improper mixing ratio. As for what to do..."

She turned to Lan Jinchen and said, "Mr. Lan, there are two ways to deal with it. One is to fill up the cracks with professional leak-trapping materials, and then wipe the surface of the concrete. This way, nothing can be seen from the outside, and there will still be leaks in the future." risk. The second method is to knock out the poured concrete and re-pour it. The cost of the second method is much higher. You are the boss, so it depends on you.”

"The second type." Lan Jinchen said, "My Lan Group's most important thing is quality. It is impossible to let the customers who build houses in the future bear the risk in order to save some costs."

Cheng Yingxuan said to Liu Jin, "According to President Lan."

Liu Jin nodded.

Cheng Yingxuan frowned and looked at another building under construction before reaching the second floor, "Which company's concrete is used in Building No. [-]?"

Liu Jin said, "Yongming Commercial Concrete."

Lan Jinchen frowned, "Cheng Gong, as a senior engineer, you don't know which concrete company you used?"

"Mr. Lan, I have just been promoted. I am only responsible for the construction of the No. [-] building of the Lanyue project, and deal with the technical problems that cannot be solved by the entire Lan's construction." She said, "The subdivision of the No. [-] building is not under my control. .”

"So that's the case." Lan Jinchen nodded and asked Liu Jin, "The floor slab is being poured for Building No. [-]. What grade of concrete is used?"

"C35." Liu Jin replied anxiously.

Lan Jinchen asked Cheng Yingxuan, "What does Cheng Gong think?"

She glanced at Liu Jin's face, "Building No. 35 is built with a height of 30 floors, and now it is poured to the second floor, and there is no need to use C25 concrete. C28 concrete can reach 60 MPa in seven days, and 28 days. The strength is 30 times that of seven days, and 35 days is 30 MPa higher than that of 30 days. Concrete is different from self-mixing. The longer the time, the higher the strength. The strength of C[-] concrete is sufficient. The cost of C[-] is higher than that of C[-]. Considering the cost, the C[-] is still affordable."

In her position, she is not only responsible for the safety of high-rise buildings, but also saves money for the boss. Otherwise, why invite her?
"What Cheng Gong said is true." Liu Jin nodded quickly.

Lan Jinchen is not easy to fool, "Liu Jin, as a supervisor, you don't know that you don't need to use C35 concrete?"

"I..." Liu Jin could only lie, "I just want the building to be stronger."

"That's really the case, that would be the best. If you secretly play tricks..." Before Lan Jinchen finished speaking, Liu Jin was already dripping cold sweat on his brow. Judging by his appearance, it was obvious that he had something in his heart.

Cheng Yingxuan has been running on the construction site since her freshman year. Of course, she knew that Supervisor Liu was pocketing his own money. He must have let the company pay C35 to buy concrete. In fact, the quality of the C30 delivered by the mixing station was included in his own money. pocket.As long as the quality is not affected, it is not convenient for her to talk about it.
