Technical Field

The invention relates to the technical field of building materials, in particular to a retarding type pervious concrete cementing reinforcing material and a preparation method thereof.

Background

Pervious concrete, also called porous concrete, sand-free concrete, pervious terrace, it is a porous lightweight concrete mixed by aggregate, cement, reinforcing agent, and water, it does not contain fine aggregate, pervious concrete is by the surface of coarse aggregate coats a thin layer of cement mortar and coheres each other and forms the cellular structure that the pore space distributes evenly, so have ventilative, pervious to water and light in weight characteristic, pervious concrete while meeting the strength requirement, still need keep certain through hole to meet the requirement of water permeability, therefore in compounding, except choosing suitable raw materials, still need to reach the purpose of guaranteeing intensity and porosity through formulation design and preparation process and additive, pervious concrete is made up of aggregate, cement, water, etc., adopt coarse aggregate of single-grain grade or discontinuous grain grade as the skeleton, the consumption of the fine aggregate is controlled within 20% of the total aggregate generally, the cement can be selected from portland cement, ordinary portland cement and slag portland cement, the admixture can be selected from silica fume, fly ash, slag fine powder and the like, when the admixture is fed, the cement, the admixture and the coarse aggregate are firstly added, half of the water dosage is added, the mixture is stirred for 30s, then the additive (additive, pigment and the like) is added, and the mixture is stirred for 60 s; and finally, adding the residual water, stirring for 120s, and discharging, wherein the cementing reinforcing material is required to be added into the pervious concrete in the production process, so that the concrete can be well coagulated.

Most of the existing permeable concrete cementation reinforcing materials are directly added with reinforcing aggregates to improve the impact resistance and the wear resistance of concrete, however, the modification reinforcing effect of the existing permeable concrete cementation reinforcing materials is not obvious, the aim of retarding cannot be realized, the aim of improving the components of the reinforcing materials by improving the components of the reinforcing materials cannot be achieved, the aim of improving the internal performance of the concrete is higher, the reinforcing fiber composite materials, fillers and reinforcing additives cannot be used in a coordinated and matched mode, the effect of the reinforcing materials is optimal, the aim of enabling the reinforcing materials to have the effect of retarding by using a water reducing agent and a hydrophobing agent and controlling the proportion of the water reducing agent and the hydrophobing agent cannot be achieved, and therefore great inconvenience is brought to the use of people.
