Explosion-proof heat-resistant concrete

Abstract

The invention discloses anti-explosion heat-resisting concrete. The concrete consists of a component A and a component B, wherein the component A consists of high-alumina refractory brick aggregate, common 32.5 Portland cement, quartz powder, sodium tripolyphosphate and first fibers, the component B consists of basalt aggregate, quartz sand aggregate, aluminate cement CA-50, Elkem 92U silica fume, argillaceous refractory brick fine powder, anti-explosion fibers, sodium hexametaphosphate and second fibers, and the mass ratio of the component A and the component B is 1:(1-1.5). By using the anti-explosion heat-resisting concrete provided by the invention, the obtained construction not only has high strength, but also has an anti-explosion character, and safe guarantee of construction which has special requirements is provided. Modified polyester hollow fiber membranes and modified polyvinyl alcohol fibers are added, so that the anti-explosion property of the concrete is greatly increased.

Description

technical field [0001] The invention relates to concrete, in particular to an explosion-proof heat-resistant concrete material. Background technique [0002] The explosion-proof performance of concrete in the prior art is usually realized by its own strength. Although there have been researches on concrete with negative Poisson's ratio in recent years, these concretes are still in the stage of theoretical research, and there is still a long way to go from practical application; The reason is that the strength of these concretes with negative Poisson's ratio in the prior art is often very poor, but in most of the occasions where concrete is used in practice, first of all, the strength of concrete should be utilized, and secondly, its anti-blast strength should be used. performance. Therefore, the development of a concrete with negative Poisson's ratio and high strength has become the goal pursued by people. Contents of the invention [0003] In view of this, the present i...
