Abstract

The invention discloses a concrete used for bottom bearing walls. The concrete is produced by uniformly blending the following raw materials with the following ratio: 95-135 kg / m<3> of water, 290-340 kg / m<3> of cement, 30-70 kg / m<3> of fly ash, 890-1020 kg / m<3> of ore powder, 788-875 kg / m<3> of sands, 120-1040 kg / <3> of fine stone, and 3.5 kg / <3> of an additive. The concrete has the advantages of reasonable design and wide application scope.

Description

technical field [0001] The invention relates to the technical field of concrete for design construction, and in particular relates to a concrete for a bottom load-bearing wall. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. concrete. Concrete is the most widely used and used building material in civil engineering. Design and manufacture concrete according to the predetermined performance, and develop new varieties of lightweight, high-strength, and multi-functional concrete. [0003] The existing concrete mix design is unreasonable, cannot be applied to the needs of existing production and life, and the cost ...
