Porous material, preparation method and application

Abstract

The invention discloses a porous material and a preparation method thereof. The material is prepared from equant ceramic, ordinary portland cement, a superplasticizer, an interface binding agent and water which are subjected to stirring, compacted molding and standard curing. The material has the advantages of low density, light weight, porosity, high water absorption, excellent water permeability, self-cleaning property, good wear resistance, fine compressive strength and bending strength, rich raw material resource and simpler preparation technology; the material is mainly used for the sponge city pavement surface or a pavement seepy material in a frame structure building or a wall filling material; due to the porous character, if the surface is not subjected to special treatment, the material can be used as a pavement seepy material of a sponge city, after the surface is sealed by materials such as building mortar, the material can provide functions of sound insulation, heat storageand self thermal insulation for a wall material through the porosity, due to the porous character, the material can store water with the density of about 400 Kg / m<3>, after water absorption saturation is reached, water permeability can be achieved, and thus the material confirms to the development ideas of the sponge city or the green building.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a porous material, a preparation method and an application. Background technique [0002] Road materials, especially the facing bricks of urban sidewalks, often use clay bricks, lime sand bricks, machine-made sand concrete blocks, fly ash steam-cured bricks, etc. Their common advantages are: simple production, wide source of materials, single brick Lighter in weight, easier to lay, wider to adapt to, can be standardized in production, and has strong replaceability after damage. The main defects are: low compressive strength and flexural strength, poor water absorption and permeable ability, insufficient weather resistance, some materials consume a lot of energy, and some materials have poor quality stability. High temperature stability requirements, etc. The concept of sponge city construction and development requires that pavement materials, stable layers, and subgrad...
