Problems solved by technology

However, these patent documents all have an obvious commonality, using wind-blown sand or artificial sand as fine aggregate, cement as cementitious material, and adopting various organic resins as surface layer binders on the surface or upper layer of permeable bricks. Bricks have the disadvantages of low overall strength and easy aging

Abstract

The invention discloses a novel light-weight high-strength sand-based water-permeable brick and a preparation method thereof. The water-permeable brick comprises, in parts by mass, 100 parts of geopolymer cement, 5-12 parts of a reinforcing agent, 1-10 parts of a thickener, 350-650 parts of high-strength pottery sand, 1.5-3.5 parts of a setting accelerator, 3-5 parts of a coloring agent, 0.5-3.0 parts of a water reducing agent and 15-20 parts of water. Mixing and stirring in a stirrer or a mixer are performed multiple times, and then the obtained mixture is placed in a brick making machine for vibration molding. Steel slag, fly ash and other large solid waste are utilized, and the defects of easily blocked pores, short water-permeable effective period and large density of existing water-permeable bricks are overcome. The prepared water-permeable brick has good water permeability, long water permeable effective period, high compressive strength and low density, and can be widely applied to sponge cities and other municipal engineering construction, the utilization added value of steel slag and other large solid waste is improved, and the ecological environment is protected.

Description

technical field [0001] The invention belongs to the field of municipal construction, in particular to the field of sponge city construction, and particularly relates to a novel lightweight high-strength sand-based permeable brick and a manufacturing method thereof. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. use. Sponge city construction is a construction mode that has a low impact on the water environment. The most important thing is to transform the original hard impermeable concrete pavement into a permeable pavement. Permeable bricks have become the most important material and material for sponge city construction. product. [0003] The current permeable bricks basically belong to the series of coarse aggregate concrete with stone as the aggregate and cement as the cementitious material. This kind of permeable brick has the disadv...
