Ecologic water-permeable brick and making method thereof

Abstract

The invention discloses an ecologic water-permeable brick and a making method thereof. The water-permeable brick comprises, by weight, 10-35 parts of a gelling material, 60-80 parts of aggregates, 1-5 parts of an additive and 2-30 parts of water. The making method comprises the following steps: 1, mechanically activating an admixture; 2, carrying out heat-alkali dual activation on the admixture; 3, mixing and stirring the gelling material; 4, carrying out compaction molding on the water-permeable brick; and 5, curing the water-permeable brick. The method provides the water-permeable brick with excellent performances for the market, gradually supplements increasing scarce underground water resources, improves the urban ecologic environment, and has good social and economic benefits.

Description

technical field [0001] The invention relates to a permeable brick and a preparation method thereof, in particular to an ecological permeable brick and a preparation method thereof. Background technique [0002] At present, with the development of cities, the requirements for pavement materials are getting higher and higher. In recent years, studies on the impact of urban development on the surrounding and underground environments have shown that: groundwater near cities decreases, ground sinks, soil moisture content is low, flowers and plants Tree growth is inhibited. Researchers believe that it is related to the urban ground structure. At present, the concrete and other paving bricks in most urban roads are impermeable and airtight. As a result, rainwater and snowwater in nature cannot effectively penetrate into the ground, destroying the ecological environment. Therefore, the demand for water-permeable and air-permeable road paving materials is increasing. Due to the c...
