Abstract

The invention provides concrete and a preparation method thereof. The concrete comprises, by weight, 250 to 350 parts of cement, 300 to 500 parts of a building waste aggregate, 100 to 150 parts of a foaming material, 5 to 10 parts of a foaming agent, 15 to 30 parts of an anti-cracking additive and 100 to 150 parts of water. The preparation method solves the environmental pollution problems caused by construction wastes and reasonably reduces the cost of the concrete. The prepared concrete has good compression resistance, shearing resistance and water resistance, greatly enhances the crack resistance and impermeability of the concrete and greatly prolongs the waterproofing period of buildings.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a concrete and a preparation method thereof. Background technique [0002] With the increasing number of ready-made concrete in the market, the competition in the ready-made concrete market is becoming increasingly fierce, and the high-profit era of ready-made concrete enterprises has long passed. Faced with this situation, only by reducing the production cost of commercial concrete can the competitiveness of commercial concrete be increased in the market. How to control the cost reasonably and effectively is the key to the survival and development of commercial concrete manufacturers. [0003] At the same time, in recent years, the domestic requirements for energy conservation, environmental protection and environmental protection have been continuously improved, the energy conservation work in residential construction has been deepened, energy conservation standards have been...
