Problems solved by technology

Because the cement concrete pavement has to withstand the repeated impact, vibration and friction of high-speed and high-load vehicles, and it has to withstand various harsh climates such as high temperature and heavy rain in summer, freezing and thawing cycles in winter, expansion stress caused by temperature differences between the road surface and the roadbed, etc. , these unfavorable factors will cause damage to the road surface and reduce durability

Abstract

The invention discloses a road concrete, comprising asphalt, dark silicon powder, black iron powder, lime powder, low-heat cement, steel slag, water, water reducing agent, antiwear agent and antifreeze agent, wherein the antifreeze agent is amine salt of acidity isooctyl-phosphite and alkylamine, the mass ratio is 1: 1, the steel slag is pretreated steel slag, and the pretreatment comprises steamcuring and magnetic separation for iron removal and sieving. The road paved with the concrete in the invention improves the abrasion resistance of the road surface and reduces the risk of the road surface skidding in winter; at the same time, not only the condensation is normal, the early strength is high, but also the road concrete has features of good workability, no segregation, no bleeding, and fast construction speed.

Description

technical field [0001] The invention relates to the technical field of roads, in particular to road concrete. Background technique [0002] Road construction materials include cement concrete, asphalt concrete, and sand and gravel materials. From the perspective of technical quality and performance of the road surface, cement concrete pavement is the best. It has a large bearing capacity, good resistance to oil erosion, small pavement resistance, and long service life. It is long, easy to maintain, and low in cost. Although the one-time investment is high, it has high comprehensive benefits and has been widely used by people. Because the cement concrete pavement has to withstand the repeated impact, vibration and friction of high-speed and high-load vehicles, and it has to withstand various harsh climates such as high temperature and heavy rain in summer, freezing and thawing cycles in winter, expansion stress caused by temperature differences between the road surface and th...
