Abstract

The invention discloses a C30 concrete and a preparation method thereof. The C30 concrete is characterized by comprising the following components in parts by weight: 140-150 parts of cement, 800-850 parts of coarse aggregate, 20-30 parts of admixture, 10-20 parts of reinforced fibers, 6-8 parts of a water retaining agent, 4-6 parts of an addition agent and 100-110 parts of water. The reinforcing fiber comprises a lignocellulose and a modified bamboo fiber in a weight ratio of 1:1. According to the C30 concrete preparation method, the concrete can have certain water-retaining property while being quickly permeable through the matching of the reinforcing fibers and the water retaining agent, so that the concrete is prevented from being dried and shrunk, and the crack resistance of the concrete is improved.

Description

technical field [0001] The invention relates to the technical field of concrete, more specifically, it relates to a C30 concrete and a preparation method thereof. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures in appropriate proportions, uniformly stirred, compacted and cured. Concrete has the advantages of low cost, convenient construction and good controllability. In recent years, the application of concrete in urban construction has become more and more extensive. However, with the extensive application of concrete, a series of problems have also arisen. At present, urban roads are usually covered by impermeable concrete pavement. Compared with natural soil, impermeable concrete pavement will reduce the air humidity in the city and accelerate the formation of urban heat island effect; and the leakage of impermeable co...
