A kind of pavement concrete for municipal construction engineering

Abstract

The invention discloses a pavement concrete for municipal construction engineering, which comprises the following raw materials in parts by weight: 40-50 parts of cement, 10-15 parts of diatomaceous earth, 5-10 parts of glyceryl monostearate, 3 parts of sodium monofluorophosphate ~5 parts, 3~5 parts of sodium alginate, 6~8 parts of water reducing agent, 10~15 parts of swelling fiber anti-cracking and waterproofing agent, 3~5 parts of amorphous calcium heptaaluminate, 4 parts of silane coupling agent ~6 parts, 1~2 parts of Vaseline, 4~6 parts of acrylic emulsion, 1~2 parts of fatty alcohol polyoxyethylene ether, 1~2 parts of defoamer and 30~40 parts of water. Compared with the existing technology, by adding diatomite and diatomite within the particle size range of 3 to 12 μm, the phenomenon of cracks in concrete can be better solved and the strength of concrete can be improved; glyceryl monostearate can also improve the strength of concrete. The strength of concrete. In summary, the pavement concrete for municipal construction projects prepared by this scheme has the advantages of high toughness, impact resistance, crack resistance, wear resistance, and skid resistance.

Description

technical field [0001] The invention relates to the technical field of municipal construction roads, in particular to road concrete for municipal construction projects. Background technique [0002] At present, the road pavement materials in my country's municipal construction projects mainly include asphalt concrete and cement concrete. Seasonal anti-deformation ability is poor, it is easy to be brittle and cracked at low temperature in winter, and poor durability. Cement concrete pavement has the advantages of long service life, small maintenance workload, low resource consumption, simple construction, and strong adaptability to traffic levels and environments. However, ordinary concrete is a typical brittle material with low bending and tensile strength and deformation capacity. Therefore, the cement concrete pavement has high brittleness, poor driving comfort, weak impact resistance and fatigue resistance, easy brittle fracture, and premature surface structure damage. ....
