Raw materials of the highway concrete comprise: Portland cement, gravel, ceramsite, pumice, expanded perlite, glazed hollow beads, fishbone dust, carbon fiber, polyimides fiber, a polychloroprene emulsion, epoxy resin, sulphur, sodium alkyl benzene sulfonate, a polycarboxylate superplasticizer and modifiedlignin fibre. The invention brings forward highway concrete with thermal insulation effect and good durability. The highway concrete with thermal insulation effect and good durability has a certain thermal insulation effect and good durability.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a concrete with good heat insulation and durability for road use. Background technique [0002] Concrete refers to the collective name of engineering composite materials that use cementitious materials (cement) to bond aggregates into a whole. Since its inception, concrete has quickly become one of the most popular and widely used building materials, which greatly accelerates the construction of national infrastructure projects. development, especially the development of road construction. Due to the complexity of the road environment, there are certain requirements for the material and quality of concrete. At present, the heat insulation and durability of road concrete are still slightly insufficient, and urgently need to be improved. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a con...
