Organic and inorganic compound cemented water-permeable brick and preparation method thereof

Abstract

The invention discloses an organic and inorganic compound cemented water-permeable brick. Two aggregates in different grain size and an organic and inorganic compound cementing agent are mixed and prepared into the water-permeable brick. The organic and inorganic compound cementing agent is a hydrophilic compound cementing agent which is formed by compounding an organic cementing agent with an inorganic cementing agent, wherein the organic cementing agent is formed by grafting and copolymerizing organic matter monomer hydroxy-propyl acrylate, acrylamide, sodium dodecyl benzene sulfonate and propyl trimethoxy silane under a cement hydration environment; the weight of the fine aggregate is 10-30% of the weight of coarse aggregate; in 100 weight parts of aggregates, the content of the organic and inorganic compound cementing agent is 5-30%. The invention also provides a preparation method for the organic and inorganic compound cemented water-permeable brick; the process is simple; the organic and inorganic compound cemented water-permeable brick disclosed by the invention has the advantages of low cost, high strength, high abrasive resistance, excellent water permeability performance, and the like.

Description

technical field [0001] The invention relates to the field of permeable bricks, in particular to an organic-inorganic composite cemented permeable brick and a preparation method thereof. Background technique [0002] With the development of the city, the urban surface is gradually covered by buildings and various water-blocking materials. Marble, glazed brick, cement, asphalt and other impermeable materials harden every corner of the city, causing very adverse effects on the urban environment: When it rains, because it cannot penetrate into the ground, it is easy to form waterlogging and increase the burden on drainage facilities; because the groundwater cannot be replenished, the groundwater level drops, resulting in urban road surface subsidence, municipal greening vegetation is difficult to grow normally, and the heat island effect becomes more and more obvious. Using permeable materials instead of non-permeable materials to build urban pavements plays a very active and im...

Problems solved by technology

Ceramic permeable bricks are made of waste slag, waste glass material, waste ceramics and domestic garbage, etc., and fired from sludge or clay. They are characterized by high strength, good water permeability, and solid waste can be used, but there are complex production processes, Disadvantages such as high energy consumption, high cost, low production efficiency, and large investment scale; concrete permeable bricks use sand, massive solid waste, and gravel as aggregates, and cement as the cement, and are pressed and maintained after a reasonable mix ratio. The process is simple and the price is low, but due to the poor cement bonding performance, it is easy to cause hole blockage when the amount is large, and the compressive strength of the permeable brick is low when the amount is sm
