Abstract

The invention discloses high-strength concrete. The high-strength concrete comprises cement, straw, silicon dioxide aerosol, bentonite, fly ash, graphite powder and reinforcing agents. The high-strength concrete has the advantages that the high-strength concrete is environmentally friendly and is high in strength, and the safety of buildings can be effectively improved by the aid of the high-strength concrete.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a high-strength concrete. Background technique [0002] Due to its high strength, high corrosion resistance and durability, high-strength high-performance concrete can reduce the size of the structure, reduce the weight of the structure, save land, reduce energy consumption, and reduce the cost of structural maintenance and reconstruction. Its technical development has become the focus of the construction industry. One of the concrete technologies studied and paid attention to. At the same time, with the development trend of high-rise and super-high-rise, long-span, underground and harsh environments in architectural design, high-strength and ultra-high-strength high-performance concrete has a prominent role in large-scale projects such as super high-rise buildings, cross-sea bridges, and offshore oil production platforms. application advantages. [0003] However, the prior art heavy co...
