Water permeable brick and preparation process thereof
The invention discloses a water permeable brick and a preparation process thereof, and relates to the technical field of water permeable bricks. The water permeable brick comprises the following components by weight: 40-50 parts of cement, 120-150 parts of stone, 12-15 parts of water, 3-5 parts of a mineral admixture and 1-3 parts of a water permeable binder. The specific preparation process of the water permeable brick comprises the following steps of: (1) raw material preparation; (2) raw material proportioning; (3) mixing and stirring; (4) base material preparing; (5) compression molding; and (6) maintaining. According to the invention, the water permeable binder is added in the proportion, so that the binding capacity among the components can be improved, the strength and water permeability of the water permeable brick can be improved, and the compressive strength, breaking strength and frost resistance of the water permeable brick can be improved. The preparation process is simple, the cost is low, the compressive strength of the prepared water permeable brick can reach 30-50 MPa, the breaking strength can reach 4-6 MPa, the water permeability coefficient is 1-20 mm/s, and thewater permeable brick has the advantages of being high in compressive strength, good in breaking resistance, high in water permeability and long in service life.
本发明公开了一种透水砖及其制备工艺，涉及透水砖技术领域，所述透水砖按重量份包括以下组分：水泥40～50份、石子120～150份、水12～15份、矿物掺合料3～5份和透水粘结剂1～3份，所述透水砖的具体制备工艺包括以下步骤：(1)原料准备；(2)原料配比；(3)混合搅拌；(4)基材配制；(5)压制成型；(6)养护。本发明配比中添加有透水粘结剂，能够提高各组分之间的结合能力，增加透水砖的强度及透水性能，提高透水砖的抗压、抗折强度和抗冻性；该制备工艺简单，成本较低，其制得的透水砖抗压强度可达30～50MPa，抗折强度可达4～6MPa，透水系数为1～20mm/s，具有耐压强度高、抗折性能好、透水性能强、使用寿命长的优点。
