Production process of inorganic non-watertight water retention environment-friendly brick

Abstract

The invention discloses a production process of an inorganic non-watertight water retention environment-friendly brick. The production process comprises the following steps that S1, water is added into cement, aggregate and sand; mixing and stirring are performed to obtain a base material; S2, an additive A, an additive B, an additive C and an additive D are added into the base material prepared in the step S1 to be mixed; after uniform mixing and stirring, materials are subjected to vibration pressurization formation; demolding is performed to prepare a brick body; S3, pigment is coated on the brick body prepared in the step S2; natural curing is performed; the inorganic non-watertight water retention environment-friendly brick finished product can be obtained. The inorganic non-watertight water retention environment-friendly brick has high non-watertight capability; the non-watertight coefficient can reach 3.29*10<-2>cm / s or higher; the inorganic non-watertight water retention environment-friendly brick can be widely applied to building cells, squares, park sidewalks, town roads and the like; due to the splitting tensile strength, the service life of the brick can be prolonged; the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a production process of inorganic water-permeable, water-retaining and environmentally friendly bricks. Background technique [0002] At present, the floors of city squares, commercial streets, sidewalks, community activity sites, parking lots, etc. are mainly paved with impermeable materials such as granite, marble, glazed tiles, cement and asphalt. The impermeable floors are very harmful to the urban environment. When it rains, the impermeable ground completely prevents the rainwater from infiltrating directly into the ground, and the accumulated water makes it very inconvenient for people to travel; the precious water resources eventually flow away with the drainage pipes, which increases the burden on urban drainage facilities; The large loss of rainwater makes it difficult for the groundwater level to rise, which directly affects the health ...
