Inorganic permeable water-retaining cement concrete gelatinizing agent and preparation method thereof

Abstract

The invention provides an inorganic permeable water-retaining cement concrete gelatinizing agent and a preparation method thereof. The gelatinizing agent is prepared from: by weight, ferrous sulfate 13-18%, ferric sulfate 3-9%, sodium sulfate 2-8%, magnesium chloride 3-9%, potassium sulfate 2-8%, ammonium sulfate 2-4%, calcium chloride 18-20%, dispersing agent 0.05-0.15%, sodium gluconate 0.05-0.15%, and water 23.7-56.9%. The compression resistance, breaking strength, skid resistance, and abrasive resistance of the permeable water-retaining cement concrete are improved when adding the gelatinizing agent provided by the invention which is 0.5% of the total weight of the mixture. The cement concrete has good water retention, water permeability, and permeability under the premise of making each physical index remain unchanged after adding the gelatinizing agent. The gelatinizing agent can make the rainwater permeate inside of the permeable water-retaining cement concrete rapidly, can protect soil humidity, can improve the soil humidity, and can improve the survival condition of the ground plant and microbe.

Description

Technical field [0001] The invention relates to the field of gelling agents, in particular to an inorganic permeable and water-retaining cement concrete gelling agent and a preparation method thereof. Background technique [0002] According to the traditional road design theory, roads and urban roads have the characteristics of compactness, smoothness, wear resistance, and anti-skid. The surface materials are mostly dense asphalt mixtures, cement concrete, etc., so they are impervious to water. Pavement drainage mostly uses the cross slope of the road arch to allow rainwater to flow from the center line of the road to the outer lane. Urban roads are taken away through drainage pipes, and highways are drained by side ditches. In many cities, when the rainfall is too heavy, the road surface water problem will be caused due to insufficient drainage speed. [0003] The concept of sponge city is an urban ecological environmental protection system based on permeable roads. The research...
