Concrete slump degree basically is the plasticization performance that points to concrete and can pump performance, the factor that affects concrete slump degree basically has grade to distribute c...

In the production process of commercial concrete, there will occasionally be the phenomenon of insufficient or low strength of construction site reaction concrete structure.

The main factors affecting the slump of concrete are as follows:

The purpose of adding admixture in the process of concrete mixing is to use different admixture to change its performance, thereby improving the application efficiency of concrete, so that the appl...

Each kind of concrete admixture has its unique function, adding this kind of admixture, can improve the performance of a certain aspect or some aspects of concrete.

1, may be caused by the problem of cement varieties, such as the mixed use of different varieties of cement, so it will lead to the phenomenon of color difference on the surface of concrete.

Because the quality level of admixture purchased at a low price is low, in order to achieve sufficient water reduction effect, technical departments often increase the amount of admixture, resultin...

When mixing concrete, measures should be taken to control the temperature of concrete, through controlling the temperature of concrete to control additional water, reduce the slump loss speed, redu...

(1) High wind and high temperature weather, high temperature, dry air, too fast evaporation, insufficient concrete maintenance, and too fast surface evaporation, resulting in water loss of the conc...

At present, there are still many testers who take strength as the main indicator of concrete quality control, and pay little attention to the crack resistance and durability of concrete. They even ...

Proper selection of concrete mix ratio can control bleeding to a large extent, such as reducing the maximum particle size of coarse aggregate, using concrete with small slump as far as possible,

In the process of engineering construction, the problems existing in the construction technology are the main factors leading to the insufficient strength of concrete, which mainly shows the follow...
