Non-fine concrete brick and preparation method thereof
The invention discloses a non-fine concrete brick, which comprises the following raw materials in parts by weight: 60-120 parts of Portland cement, 10-20 parts of stones and 23-46 parts of water. Thenon-fine concrete brick has the beneficial effects that the non-fine concrete brick is free of fine aggregate, a large number of large pores exist in the concrete brick, water can flow in the hardenednon-fine concrete brick, a filtering effect is achieved, a drainage function is not affected, invasion of water spots and silt to a blind pipe is reduced, and the drainage efficiency is greatly improved.
本发明公开了一种无砂混凝土砖，包括下述重量份的原料：硅酸盐水泥60‑120份、石子10‑20份和水23‑46份。本发明的有益效果为：本发明所述一种无砂混凝土砖由于没有细骨料，混凝土砖的内部存在着大量较大的孔隙，水可以在硬化的无砂混凝土砖中流动，即起到了过滤的效果，也不影响排水功能，降低了水渍、泥沙对盲管的侵入，大大提高了排水效率。
