The average weight of concrete is over 2500 kg, that of ordinary concrete is about 2000 kg, and that of lightweight concrete is about 1950 kg.

Cement, sand, stones and water must be mixed into concrete to reach a certain proportion. Because concrete has different grades, such as C20, C30, C40, C50 and so on, the weight is different.

What are the characteristics of concrete?

1, workability

This is a very important property of the coagulation complex, which can directly reflect the consistency, fluidity, plasticity, anti-bleeding, plastering performance of the complex, so it is directly related to the later construction progress.

2. Strength

The more important mechanical properties of concrete after hardening, that is, the ability of concrete to resist compression, tension, bending and shearing. Water-cement ratio, type and dosage of cement, type and dosage of aggregate, mixing, molding and curing will directly affect the strength of concrete itself.
