Problems solved by technology
[0003] The prior art discloses concrete with many proportions, which are generally obtained from cement, sand, water, admixtures and admixtures. In order to obtain concrete with better strength and durability in the later stage, the prior art generally adopts the method of reducing the gray ratio, providing The method of cement consumption, but cement is a high-energy-consuming industry. During the calcination of cement clinker, a large amount of raw coal is consumed, and a large amount of dust and harmful gases are generated, so the cost is relatively high

Description
technical field [0001] The invention relates to the construction field, in particular to a self-compacting concrete. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials, and is widely used in civil engineering. [0003] The prior art discloses concrete with many proportions, which are generally obtained from cement, sand, water, admixtures and admixtures. In order to obtain concrete with better strength and durability in the later stage, the prior art generally adopts the method of reducing the gray ratio, providing However, cement is a high-energy-consuming industry, and a large amount of raw coal is consumed during the calcination of cement clinker, and a large amount of dust and harmful gases are produced, so the cost is relatively high. Contents of the invention [0004] The invention provides a self-compacting concrete, which adopts the following technical...
