Extremely-high-strength concrete

Abstract

The invention discloses a concrete with excellent strength. The concrete is uniformly mixed with the following raw materials: water 145-158kg / m³, cement 197-221kg / m³, fly ash 97-108kg / m³, sand 735‑824 kg / m³, pebbles 1320‑1521 kg / m³, wood calcium 1.4‑2.93 kg / m³, bentonite 543‑621.9 kg / m³, admixture 3.9‑4.0 kg / m³, debris 386‑394 kg / m³ and waste Stone 488‑495 kg / m³. The invention has the advantages of reasonable design and wide application range.

Description

technical field [0001] The invention relates to the technical field of concrete for designing buildings, and in particular relates to a kind of concrete with excellent strength. 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...
