Mixed concrete

Abstract

The invention discloses a mixed concrete, which is characterized by being composed of the following components in parts by weight: 300 to 500 parts of cement, 200 to 300 parts of yellow sand, 150 to 350 parts of fine aggregate sand, 150 to 350 parts of coarse aggregate sand, 5 to 10 parts of reinforcing agent, and 100 to 200 parts of water. The raw material resource is stable, the raw materials are environment-friendly and have little toxicity, and the production and manufacture are simple. A better synergetic effect can be achieved by determining the components and the component content ranges. Gas-phase titanium dioxide and gas-phase alumina are co-used with sodium metasilicate pentahydrate to effectively reduce the sensitivity to silt content; volcanic ash is co-used with alumina to effectively enhance the anti-corrosion performance of concrete; isopropanol and triethanolamine are used together to improve the work performance and state of concrete and increase the concrete later strength.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a mixed concrete. Background technique [0002] Concrete, referred to as concrete for short, refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, 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, also known as ordinary concrete. It is widely used in civil engineering. [0003] Concrete is one of the most important contemporary civil engineering materials. It is prepared in a certain proportion by cementitious materials, granular aggregates (also known as aggregates), water, and admixtures and admixtures added when necessary. It is a kind of artificial stone that is uniformly stirred, densely f...
