Abstract

The invention provides a high-performance concrete based on artificial sand, a preparation method and application thereof, and relates to the technical field of concrete materials. The high-performance concrete includes the following raw materials in parts by weight: 380-400 parts of cement, 40-50 parts of biomass activated ash, 25-40 parts of silica fume, 95-105 parts of slag powder, 740-830 parts of artificial sand, and 530 parts of gravel. ~545 parts, 2~6 parts of continuous fiber of 0.16~2.5mm, 2~5 parts of graphite microspheres, 5~8 parts of stone powder modifier, 8~10 parts of admixture, 205~225 parts of water. The high-performance concrete of the invention has high-strength performance of C100, compact structure, good durability, good impermeability and frost resistance.

Description

technical field [0001] The invention relates to the technical field of concrete materials, in particular to a high-performance concrete based on artificial sand and its preparation method and application. Background technique [0002] With the continuous deepening of the concept of sustainable development in the minds of Chinese people and the continuous improvement of energy conservation and environmental protection requirements, the construction industry represented by the prefabricated concrete structure system has received more and more attention, and its application has gradually heated up. The prefabricated concrete structure has a short construction period, low production cost, good product quality, easy control of the production process, and greatly improved production efficiency; the prefabricated concrete structure has less energy consumption, less sewage discharge, and high material utilization in the production process. Requirements for green production and susta...
