Abstract

The invention belongs to the field of inorganic non-metal materials, and discloses a ceramic water permeable brick and a production method thereof. The ceramic water permeable brick is prepared from an aggregate, a binding agent and a combustible raw material; heat generated during a combustion process of the combustible raw material can be used for heating a green brick from inside to outside, and meanwhile, a kiln is used for heating the green brick from outside to inside, so that the uniformity of inner and outer structures of the green brick is increased under the combined action of insideand outside heating, and the performance of the green brick can be more uniform; in addition, the heat efficiency is increased to a large extent. Residue generated after fuel combustion can be used as the aggregate of the ceramic water permeable brick in situ and can be fully utilized, zero emission of fuel residue is realized, and the production cost of the ceramic water permeable brick is saved; in addition, the volume of the combustible raw material is lessened after combustion, larger pore diameter is formed between residue particles, and meanwhile, certain gaps are formed in the residueper se, so that the properties of high strength and good water permeability are given to the ceramic water permeable brick through the special structure. During roasting of the ceramic water permeablebrick, a gradient temperature rising mode is adopted, the combustible raw material can be fully combusted, meanwhile, the green brick can be prevented from being over-combusted, and the quality of the ceramic water permeable brick is ensured.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a ceramic permeable brick and a production method thereof. Background technique [0002] With the continuous advancement and development of my country's new urbanization construction, urban public places need to be covered with a large number of pavement building materials. Traditional pavement construction materials are mainly stone, cement, ordinary ceramic square bricks, etc. The common characteristics of these materials are impermeable and airtight, and have no water retention function. Rainwater and snow water cannot effectively penetrate into the ground, resulting in reduced groundwater and ground subsidence , the soil moisture content is low, the growth of flowers and trees is inhibited, etc., destroying the ecological environment. At the same time, the impermeable pavement also blocks the exchange of water vapor and heat energy betwe...
