Abstract

The invention discloses a method for preparing recycled concrete with high shock resistance, comprising the following steps: S1. Weigh the following raw materials in parts by weight: coarse aggregate, fine aggregate, recycled aggregate, cement, fly ash, quartz sand, pearl Rock, tetrafluoroethylene, sodium ethylsiliconate, zirconium silicone, naphthenic acid soap, rosin thermopolymer, sodium alkyl benzene sulfonate, water; The surface is sprayed with tap water to make the surface of the regenerated aggregate completely wet, and the regenerated aggregate is baked in an oven until the surface of the regenerated aggregate is in a dry state before use; S3. Put all the raw materials into the mixer to stir the raw materials, and stir The recycled concrete with high shock resistance is obtained after uniformity. In the present invention, by adding quartz sand, perlite and tetrafluoroethylene to the recycled concrete, the seismic capacity of the recycled concrete can be effectively improved, so that the recycled concrete can be used in a wider range and has a longer service life. longer.

Description

technical field [0001] The invention relates to the technical field of production of building raw materials, in particular to a method for preparing recycled concrete with high shock resistance. Background technique [0002] Concrete is the man-made material with the largest output in the world. The total output of concrete in the world is 6-7 billion cubic meters per year, and the total output of concrete in my country is 3-4 billion cubic meters per year. The recycling and sustainable development of concrete is increasingly causing widespread concern. Attention, the traditional and narrow sense of recycled concrete refers to the concrete mixed with waste concrete recycled aggregates such as concrete structures as admixtures; the broad sense of recycled concrete refers to construction waste, including concrete construction waste, brick-concrete construction waste, decoration construction waste Recycled materials such as construction waste, including recycled coarse aggregate,...
