Abstract

The invention belongs to the field of concrete preparation, and particularly relates to concrete with efficient corrosion resistance and a preparation method and application thereof. The concrete is prepared from the following components in parts by mass: 300 to 400 parts of mineral rock, 300 to 500 parts of cement, 600 to 700 parts of sand, 800 to 1000 parts of stone, 10 to 15 parts of a retarder, 60 to 100 parts of fly ash, 40 to 60 parts of slag powder, 60 to 90 parts of a fiber filler, 80 to 100 parts of silica fume and 300 to 500 parts of water. The preparation method comprises the following steps: firstly, crushing and grinding the components; and finally, the aggregate is mixed with an additive, so that the concrete is prepared. The concrete prepared in the invention has good corrosion resistance. The product is simple in production process, low in cost, high in yield and suitable for large-scale industrial production.

Description

technical field [0001] The proposal belongs to the field of concrete preparation, and specifically relates to a concrete with high-efficiency anti-corrosion performance and its preparation method and application. 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, 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, which is widely used in civil engineering. Concrete is one of the most widely used building materials, and it has high strength and hardness after setting. [0003] The existing Chinese patent with the notification number CN110577390A discloses a concrete preparation process, which includes the fo...
