Lightweight water-permeable concrete containing ceramsite
The invention relates to lightweight water-permeable concrete containing ceramsite, and belongs to the field of building materials. The concrete is prepared from, by mass (kg/m<3>), 130-150 parts of mixing water, 410-450 parts of cement, 990-1000 parts of the ceramsite and 1.11-1.80 parts of additives, wherein the ceramsite is continuous grading coal gangue ceramsite with the particle sizes ranging from 5 mm to 10 mm, the ceramsite is shaped like a sphere, the stacking density grade of the coal gangue ceramsite ranges from 900 kg/m<3> to 950 kg/m<3>, the close stacking density ranges from 980 kg/m<3> to 1030 kg/m<3>, and the apparent density ranges from 1700 kg/m<3> to 1800 kg<3>. According to the water-permeable concrete, a larger amount of the coal gangue ceramsite which is formed by sintering the byproduct coal gangue raw materials in the coal mining process is used, the water-permeable concrete is excellent in performance, high in permeation coefficient, excellent in strength, low in weight per unit volume and low in price, the requirement of the concrete for natural stone is reduced, and a positive effect on solving solid emissions and atmospheric pollution is achieved.
