preparation example Construction
[0011] The preparation method of the permeable concrete binder is as follows: put each component into a mixer according to the proportion, mix and stir for 30 minutes, and then pack it into a bag after stirring evenly.
[0012] By weight percentage, the permeable concrete comprises 10%-20% cement, 2%-4% binder and 80%-90% stone, and the binder is the above-mentioned permeable concrete binder. Further optimally, the permeable concrete comprises: 14.2% cement, 2.5% binder and 83.3% stone.
[0013] The preparation method of permeable concrete is as follows: the cement, stone and binder are mixed and used in proportion. The permeable concrete can be prepared on the construction site, and put into construction immediately after the preparation is completed, so as to avoid the concrete being placed for a long time.

Abstract
The invention provides a pervious concrete binder and pervious concrete.The pervious concrete comprises cement, stones and the binder, and the binder comprises 35% of fly ash, 30% of silicon-calcium powder, 15% of calcium chloride, 5% of cellulose, 12% of resin rubber powder and 3% of retarder. The silicon-calcium powder is used for adjusting the viscosity, the calcium chloride is used for improving the strength of concrete, the cellulose is used for preventing the concrete from cracking and has a water retention function, the resin rubber powder is used for improving the bonding strength of the binder, the retarder is used for relieving the setting time of the concrete, and the binder comprises the components and the content thereof. When the binder is used for preparing concrete, the concrete has certain strength and good water permeability after being applied, and the preparation cost can be effectively reduced.
Description
technical field [0001] The invention relates to the field of concrete, in particular to a permeable concrete binder and permeable concrete. Background technique [0002] Most of the existing permeable pavements are made of cement and stones to form concrete to form a cement concrete pavement. Cement concrete pavement refers to the pavement with cement concrete as the main material as the surface layer. In order to withstand the pressure brought by vehicles of different weights, it is required that the concrete of the road surface is not easy to crack, has strong bonding strength and has a certain strength. However, the cement concrete pavement used on the sidewalk has certain strength requirements and also needs to be permeable, and has the ability to permeate and drain water in rainy days, so as to avoid water on the road surface and affect the safe passage of pedestrians. However, the water permeability of the existing cement concrete pavement is poor, and the cost of the...
