Concrete admixture as an indispensable building materials in today's building engineering,
its quality has seriously affected the quality of the project, so we must pay attention to the
grasp of the quality of concrete admixture in the selection. Once there is a problem, choose carefully.
Generally speaking, the poor quality of concrete admixtures will have the following performance:
Abnormal condensation occurs in the mixing process of newly mixed concrete, such as rapid coagulation,
false coagulation and other phenomena, resulting in fast slump loss.
2, concrete bleeding, segregation, stratification phenomenon is serious, hardening strength decreased significantly.
3, the slump of new concrete can not be raised, which may be because the water reduction effect of concrete admixture is poor.
4, the shrinkage of concrete increases, anti-seepage, durability decreases,
a large area of concrete slow setting effect is not obvious, temperature cracks.
The above is the performance of the poor quality of concrete admixtures. I hope that the majority of consumers can know
it to ensure the purchase of good concrete admixtures.
