Foam concrete is a kind of high-quality building material, which has the advantages of high strength, low water absorption and low difficulty in construction. However, before construction, attention should be paid to many aspects, such as equipment testing, cleaning the pouring position and preparing sufficient water, in order to ensure the smooth progress of construction.
According to the design weight, determine the appropriate amount of cement to ensure the quality and strength
of foam concrete. Generally speaking, the amount of cement required for 1m ³ foam concrete is between 300 and 600 kg. The roof load is 350 kg per square meter, and the minimum amount of cement is 300 kg. The weight of the indoor cushion is 400-600 kg, and the amount of cement is 350-550 kg.
It should be noted that the addition of fly ash should not exceed 40%, otherwise the strength of foam concrete will be poor, and the addition of foaming agent depends on the performance of different manufacturers.
