Abstract

The invention discloses recycled fine aggregate high-strength self-compacting concrete and a preparation method thereof.The recycled fine aggregate high-strength self-compacting concrete is prepared from, by weight, 18%-30% of artificial sand fine aggregate, 15%-22% of perlite aggregate, 10%-15% of cementing material, 10%-15% of cement, 10%-15% of superfine mineral powder, 10%-20% of water and 10%-20% of reinforced mixed material, based on the total weight of the raw materials, the proportion of the cement is 12-19%, the proportion of the superfine mineral powder is 10-16%, the proportion of the water is 10-20%, and the proportion of the reinforced mixed material is 10-20%. According to the recycled fine aggregate high-strength self-compacting concrete and the preparation method thereof, the recycled fine aggregate and the reinforced mixed material are arranged, so that the forming effect of the concrete can be improved, the microstructure of the concrete can be improved, the mechanical property and durability of the concrete can be improved, the working performance can also be improved, the strength is relatively high, and the durability is excellent; the recycled fine aggregate concrete is high in carbonization resistance, excellent in frost resistance and chloride ion permeability resistance and more practical.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a recycled fine aggregate high-strength self-compacting concrete and a preparation method thereof. Background technique [0002] Concrete is a material for building molding and positioning. It is one of the most important contemporary civil engineering materials. It has the characteristics of abundant raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of compressive strength High strength, good durability, and a wide range of strength grades make it widely used. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of concrete. [0003] There are certain disadvantages in the use of existing concrete. First, when preparing, the concrete cannot be well strengthened and prepared. The strength may be poor and the life is s...
