Environment-friendly pervious concrete and preparation method thereof

[0026] like figure 1 As shown, an environmentally friendly permeable concrete is prepared from the following raw material components in parts by weight: 100 parts of cement, 200 parts of water, 80 parts of coarse aggregate, 50 parts of fine aggregate, 20 parts of admixture, 10 parts of additives, 10 parts of coloring agent and 5 parts of thickening powder.

[0027] The cement is low-alkali cement; the coarse aggregate is crushed stone of 5 mm; the fine aggregate is crushed stone below 5 mm; the admixture is one of slag powder and fly ash; The additive is a mixture of air-entraining agent and quick-setting agent; the coloring agent is iron oxide; and the thickening powder contains rubber powder.

[0028] A preparation method of environment-friendly permeable concrete, comprising the steps of:

[0029] Step 1: Mix cement and water together and stir evenly to form cement slurry;

[0030] Step 2: adding coarse aggregate, fine aggregate and admixture to the cement slurry in step 1

[0041] like figure 1 As shown, an environment-friendly permeable concrete is prepared from the following raw material components in parts by weight: 125 parts of cement, 225 parts of water, 85 parts of coarse aggregate, 60 parts of fine aggregate, 25 parts of admixture, 15 parts of additives, 15 parts of coloring agent and 8 parts of thickening powder.

[0042] The cement is low-alkali cement; the coarse aggregate is crushed stone of 8mm; the fine aggregate is crushed stone below 3mm; the admixture is one of slag powder and fly ash; The additive is a mixture of air-entraining agent and quick-setting agent; the coloring agent is iron oxide; and the thickening powder contains rubber powder.
