Compared with the foreign foam concrete application scope, the application of the domestic is "very weak", foam concrete application is relatively widely abroad, main areas of application include: retaining wall, the runway arena, composite wall, backfi

Concrete hydration reaction is increased with time and gradually improve, under normal maintenance in the first seven days compressive strength is growing rapidly

Cement strength grade is used to represent the cement strength of high and low level, it is to put the cement and move in a ratio of 1:3

A wide variety of cement strength is different also, all kinds of performance is also different, different varieties of cement with different cement

Cement stability refers to the volume change whether is even after hardened cement, cement stability is unqualified, foam concrete cracks

How to divide the permeability resistance of foam concrete classes?If you have questions, so today we will learn together:

The strength of the foam concrete of water and foam concrete related a lot to do.Generally the mixing proportion of concrete, are calculated on dry sand
