Problems solved by technology

[0003] However, because pervious concrete generally needs to maintain certain through-holes to meet the requirements of water permeability, the internal structure of pervious concrete is relatively loose, which easily affects the strength of pervious concrete. Therefore, there is still room for improvement.

Abstract

The invention relates to the field of building materials and provides pervious concrete to solve the problem of low strength of pervious concrete. The pervious concrete is prepared from components inparts by mass as follows: 80-100 parts of water, 30-40 parts of Portland cement, 50-60 parts of broken limestone, 30-35 parts of medium sand, 4-5 parts of stearoyl chloride, 5-6 parts of a sulfamate superplasticizer, 5-7 parts of waste textile fiber and 0.5-1 part of a coupling agent. By addition of the waste textile fiber, the waste textile fiber resource can be reasonably used, pollution of thewaste textile fiber to the environment can be reduced, meanwhile, the waste textile fiber can form a disorientation support system in the pervious concrete easily, so that orientation stress of the pervious concrete is dispersed, the number and size of pervious concrete cracks can be reduced, the anti-cracking and impervious capacity of the pervious concrete are enhanced, toughness of the perviousconcrete is improved, the tensile strength and compressive strength of the pervious concrete are further improved, and the service life of the pervious concrete is prolonged.

Description

technical field [0001] The invention relates to the field of building materials, more specifically, it relates to a kind of permeable concrete. Background technique [0002] Permeable concrete, also known as porous concrete, is a kind of porous lightweight concrete made by mixing aggregate, cement, reinforcing agent and water, and it does not contain fine aggregate. [0003] However, because pervious concrete generally needs to maintain certain through-pores to meet the requirements of water permeability, the internal structure of pervious concrete is relatively loose, which easily affects the strength of pervious concrete. Therefore, there is still room for improvement. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a pervious concrete, which has the advantage of improving the strength of the pervious concrete. [0005] To achieve the above object, the present invention provides the foll...
