Question:

What are the technical points of the lioghtweight foam?concrete?

Answer:

1. To clean the surface and ensure that there is no dust and dirt of the grassroots, for smooth, solid, light pressure, does not allow rugged, loose and sand off ash and other defects. 2. To make a good preparation of the materials, the foaming agent, additives, cement and auxiliary materials should be transported to the designated place for storage. 3. It should be leveled according to the design. First, take use of the cement mortar according to 2.5x2.5m to determine the height of the slope. 4. To start the foaming machine to start to work, and then start the host. To sent the cement into the agitator with the help of the conveyor?belt/band carrier. And after it is mixed uniform to start the transportation system of foam conveying system and high-pressure pump. And then mix the concrete composite material averagely and transport them to the disignated construction area to cast. 5. According to the requirements of the construction, the professionals will smooth the castin foam concrete. (with help of the smooth floating ruler) Because after it is being smooth, the surface of the foam cement will produce a little air void which will have a bad effect of the surface of the waterproof construction. It is suggested to establish the 70% final set of the casting foam concrete and use the cement mortar to smooth and protect. 6. When the integral casting of foam concrete has reached 4000 square meters and the final set of the concrete has up to 70%( It is generally 25 centigrade and 36 hours). The cut of the dividing joint should be in time. And the width of the dividing joint should be bigger than 4x4m. The the width and depth of cutting of every dividing joint should be calculated by 1/800 telescopic value of the thermal efficiency expansion. The deepth of the width of cutting is 1.5x3.0cm, the elastic sealing material will be sealed in after the cutting.
