Water-permeable cement concrete block and preparation method thereof
The invention discloses a water-permeable cement concrete block and a preparation method thereof. The water-permeable cement concrete block is prepared from 80-120 parts of cement, 610 parts of mica powder, 100-120 parts of fine aggregate, 300-500 parts of coarse aggregate, 2.5-5 parts of hectorite and 100-120 parts of water. The preparation method comprises the following steps: adding hectorite into water, uniformly stirring, standing for 20-30 hours, adding the coarse aggregate, the fine aggregate and the cement, uniformly stirring, adding the mica powder, and continuously stirring for 20-40minutes to obtain pervious concrete slurry; pouring and molding the pervious concrete slurry, maintaining the molded concrete for 24-72 hours at the temperature of 25-33 DEG C, and then maintaining the molded concrete for 3-14 days in the open air. The cement concrete building block prepared by the method is small in air shrinkage deformation and good in water permeation effect, is beneficial todrainage and water seepage of a paved building block road, has a good water retention effect, and is beneficial to inhibition of ground dust pollution.
本发明公开了一种可透水水泥混凝土砌块及其制备方法，原料包括水泥80‑120份、云母粉6‑10份，细骨料100‑120份，粗骨料300‑500份，锂皂石2.5‑5份，水100‑120份；制备方法为将锂皂石加入到水中，搅拌均匀后静置20‑30h，然后加入粗骨料、细骨料份和水泥，搅拌均匀后，加入云母粉，继续搅拌20‑40min，得透水混凝土浆体；透水混凝土浆体进行浇筑成型，成型后的混凝土在温度25～33°C下养护24~72h，然后露天养护3~14天。通过该方法制备的水泥混凝土砌块干缩变形量小且透水效果好，有利于铺设的砌块道路的排水和渗水，同时该水泥混凝土砌块具有良好的保水效果，有利于抑制地面粉尘的污染。
