Application of high-content pebbles in concrete
The invention provides an application of high-content pebbles in concrete. The concrete comprises raw materials in parts by weight as follows: 80-110 parts of cement, 40-70 parts of coal powder ash, 85-95 parts of pebbles, 40-50 parts of fine sand and 12-16 parts of a foaming agent, wherein a ratio of water, the cement, the coal powder ash, the pebbles, the fine sand and the foaming agent is kept to be 0.5-0.65, the cement, the sand, ground fine mineral powder, the coal powder ash and a water reducing agent are put in a large mandatory type stirrer and stirred for 30 min, the high-content pebbles are added for stirring, and the stirring time is not shorter than 120 min. According to the application of the high-content pebbles in the concrete, a large quantity of sediments in a river channel is cleaned, the river channel becomes clear and smooth, large quantities of manpower and material resources for flood control are reduced, unnegligible contribution to the flood control work is provided, and great social and economic benefits can be produced.
