Cement polymer based high-temperature concrete permeable pavement bricks and manufacturing method thereof

Abstract

The invention provides cement polymer based high-temperature concrete permeable pavement bricks and a manufacturing method thereof and belongs to the field of road surface pavement materials. Each cement polymer based high-temperature concrete permeable pavement brick is prepared from a permeable base layer and a permeable surface layer, wherein the permeable base layer is prepared from 290 to 345 parts of cement A, 0 to 6 parts of ultra-light aggregate A, 1630 to 1765 parts of coarse aggregate, 255 to 290 parts of sand, 0.50 to 0.85 part of polymer emulsion A, 0.35 to 0.50 part of an interface reinforcing agent A and 0 to 0.65 part of a loose soil constriction resisting agent; the permeable surface layer is prepared from 390 to 425 parts of cement B, 0 to 2 parts of ultra-light aggregate B, 0 to 7.5 parts of micro-pore fine aggregate, 1350 to 1400 parts of wear-resisting fine aggregate, 0.65 to 0.85 part of polymer emulsion B, 0.65 to 0.95 part of an interface reinforcing agent B, 8 to 13 parts of a deicer salt scaling resisting and alkali adsorption agent and 15 to 17 parts of pigment. According to the cement polymer based high-temperature concrete permeable pavement bricks, all technological performances of the permeable bricks are comprehensively improved.

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...

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
