Problems solved by technology

The surface of this kind of permeable brick is dense, although it is not easy to be blocked by particles such as lime sand and mud, but due to the dense surface, its water permeability is significantly worse; (3) The permeable surface with sand as fine aggregate and cement as cementitious material The layer is easy to crack and it is difficult to meet the requirements of the national standard "Permeable Pavement Bricks and Permeable Pavement Panels" (GB / T25993) for frost resistance D35 and D50; (4) Concrete prepared by traditional mixing technology, the bonding force between aggregates Weaker, it is impossible to prepare permeable bricks with higher flexural strength and splitting tensile strength

Description

technical field [0001] The invention belongs to the field of pavement materials, and in particular relates to a cement polymer-based high-performance concrete permeable pavement brick and a manufacturing method thereof. Background technique [0002] On December 12, 2013, the "Central Urbanization Work Conference" proposed: "When upgrading the urban drainage system, priority should be given to retaining limited rainwater, giving priority to more use of natural power to drain water, and building natural storage, natural infiltration, Naturally purified sponge city". In October 2015, the General Office of the State Council issued the "Guiding Opinions on Promoting the Construction of Sponge City". In the "Guiding Opinions", it is further proposed that through the construction of sponge cities, the impact of urban development and construction on the ecological environment will be minimized, and 70% of the rainfall will be absorbed and utilized locally. By 2020, more than 20% o...
