Concrete with high anti-seismic property and preparation method thereof

Abstract

The invention provides concrete with high anti-seismic property and a preparation method thereof, and relates to the technical field of concrete materials. The concrete with the high anti-seismic property is prepared from the following raw materials in parts by weight: 400 to 450 parts of volcanic ash cement, 1180 to 1225 parts of coarse aggregate, 80 to 100 parts of coarse sand, 300 to 320 parts of medium sand, 130 to 160 parts of fine sand, 50 to 70 parts of nano calcium carbonate, 60 to 80 parts of zeolite powder, 20 to 25 parts of water reducing agent, 0.1 to 0.15 part of air entraining agent, 180 to 200 parts of purified water, 0.25 to 0.3 part of sodium polyacrylate, 0.09 to 0.1 part of repairing liquid and 0.1 to 0.12 part of waterproof coating. The impact crusher is used for crushing conglomerate, the content of needle-sheet-shaped aggregate is reduced, the toughness of the aggregate is guaranteed, the effectiveness of waterproof performance is guaranteed, the waterproof paint has good waterproof performance and elasticity and good anti-cracking effect, and if cracks occur in concrete, calcium carbonate is deposited at the cracks through calcium carbonate producing actinomycetes, so that the cracking resistance of the concrete is improved. The waterproof performance of the concrete can be kept for a long time.

Description

technical field [0001] The invention relates to the technical field of concrete materials, in particular to concrete with high shock resistance and a preparation method thereof. Background technique [0002] Concrete is mainly composed of gel material, aggregate and water. According to the actual use, appropriate admixtures and admixtures can be added to the concrete raw materials. In construction engineering, the anti-seismic performance of concrete is a necessary defensive index. The anti-seismic performance It is about human reproduction and social development. [0003] Concrete building walls with high seismic performance have good elastic-plastic properties and are not easy to crack. The seismic performance can strengthen the waterproof performance of concrete. However, there is still room for improvement in the waterproof performance of existing concrete materials, and even if the concrete has good The elasto-plastic properties of the concrete still cannot completely ...
