Rapid water seepage concrete and preparation method thereof

Abstract

The invention relates to concrete, in particular to rapid water seepage concrete and a preparation method thereof. The concrete comprises the following components in parts by weight: 80-100 parts of water, 30-40 parts of Portland cement, 50-60 parts of broken stone, 4-5 parts of stearyl chloride, 5-6 parts of a sulfamate superplasticizer, 5-7 parts of non-caking steel fibers and 0.5-1 part of a coupling agent. The non-caking fibers are composed of wave-shaped steel fibers and nylon paper adhered to one sides of the wave-shaped steel fibers. The mechanical strength of the concrete is effectively improved by adding the steel fibers, and the water seepage of pores is smooth and rapid water seepage effect is achieved because a foaming process is not adopted or fine aggregate is not added; and the steel fibers are provided with a back plate, so the possibility of hooking between the adjacent steel fibers is reduced on the premise that the elasticity and toughness of the steel fibers are not damaged, the steel fibers are prevented from being clustered and gathered in the concrete, and uniform distribution of the steel fibers is facilitated.

Description

technical field [0001] The invention relates to concrete, in particular to a rapid permeable concrete and a preparation method thereof. Background technique [0002] The so-called permeable concrete is commonly known as permeable concrete. It is a concrete that does not contain fine aggregates, so it will form relatively uniform pores inside, so as to achieve water permeability and water seepage. The disadvantages of the prior art are that the wear resistance is weak and the pressure bearing capacity is weak. [0003] Foamed concrete usually cannot be used as a substitute for permeable concrete, but because it has higher mechanical strength than permeable concrete, some merchants on the market promote foamed concrete as permeable concrete. In fact, foamed concrete consists of a foaming agent Foaming produces pores and most of the pores are blind or closed pores, with only a small number of through pores, resulting in a low water seepage rate. [0004] There is an urgent ne...

[0003] Foamed concrete usually cannot be used as a substitute for permeable concrete, but because it has higher mechanical strength than permeable concrete, some merchants on the market promote foamed concrete as permeable concrete. In fact, foamed concrete consists of a foaming agent Foaming produces pores and most of the pores are blind or closed pores, with only a few through holes, resulting in a very low water seepage rate
