The concrete has excellent compressive and flexural strength.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a modified anti-crack concrete with excellent compressive and flexural properties. Background technique [0002] At present, concrete is the most important building structure material, which is widely used in roads, construction, decoration, heavy industry and other fields. However, for concrete in high load-bearing and high-impact environments, simple concrete materials have low compressive, flexural and crack-resistant properties, so it is urgent to develop a modified crack-resistant concrete with excellent compressive and flexural properties. Solve the problems in the prior art. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a modified anti-crack concrete with excellent compressive and flexural properties. [0004] A kind of modified anti-cracking concrete with excellent com...
