    Abstract
  • To solve the problem of poor workability, fast curing and molding difficulty of common polyurethane concrete, a new water-containing unsaturated polyurethane concrete was proposed according to the requirement of high standards for aggregate in common polymer concrete.The mechanical properties of water-containing unsaturated polyurethane concrete were investigated by ratio test, strength test, water-mixed test, immersion test and field sampling test, and the effects of material properties, material ratio, temperature and moisture content on the mechanical properties were analyzed.Analysis result shows when the added amount of water is 15%-20% of unsaturated polyurethane at 10 ℃-20 ℃, the added amount of water is 20%-30% of unsaturated polyurethane above 20 ℃, the compressive strength of 1d for the water-containing unsaturated polyurethane concrete is 22.70 MPa in field engineering application and immersion test, and the phenomena of softening and disintegration are not found after long-term immersion.Obviously, the water-containing unsaturated polyurethane concrete has good stability, workability and formability that meet the engineering needs in the construction.At 15 ℃, the recommended massratio of cement, sand, stone, ZK3, water, unsaturated polyurethane, initiator, and accelerant is1.000∶5.700∶7.300∶1.300∶0.080∶2.000∶0.050∶0.025.
