Abstract

The invention discloses a sand-based water permeable brick with a high permeable rate, and belongs to the technical field of building materials. Allophane and natural zeolite are mixed, grinded and sieved to obtain mixed filler; water, the mixed filler, desert sand, binding agent, additive, silica sand and modified cotton fibers are added into a stirring machine; after mixing and stirring are carried out, mixture is added into a die, the die is moved to a brick block forming machine to be tamped and formed to obtain blank; after the blank is dried, the dried blank is dipped in ethyl orthosilicate and is filtered; the dipped blank is moved into a sintering furnace; after high-temperature sintering is carried out, artificial nourishing is carried out to obtain the sand-based water permeablebrick with the high permeable rate. The sand-based water permeable brick has good compressive strength and high permeable rate.

Description

technical field [0001] The invention discloses a sand-based permeable brick with high water permeability, which belongs to the technical field of building materials. Background technique [0002] The aeolian sand in the desert is widely distributed, which is not only a kind of hazard, but also a kind of resource. Scientific utilization can make it turn harm into benefit and waste into treasure. With the development of the economy and the acceleration of urbanization, the surface of modern cities is more and more covered by impermeable buildings, roads and concrete. This "hardening" of the surface makes it difficult for atmospheric precipitation to penetrate into the ground in time. The increase of surface runoff has formed the urban "heat island effect" and the phenomenon of waterlogging caused by insufficient drainage and urban surface subsidence, which has increased the risk of urban flood control and aggravated environmental problems such as urban drought and water shorta...
