ULTRAHIGH-STRENGTH HIGH-DURABILITY SELF-LEVELING MATERIAL AND ULTRAHIGH-STRENGTH HIGH-DURABILITY SELF-LEVELING MATERIAL HARDENED BODY

摘要

PPROBLEM TO BE SOLVED: To provide an ultrahigh-strength high-durability self-leveling material having high strength development property and high durability capable of achieving a compressive strength of 150 N/mmSP2/SPeven in an ultrahigh-strength region at a water-binder ratio of 20.0% and an ultrahigh-strength high-durability self-leveling material hardened body. PSOLUTION: The ultrahigh-strength high-durability self-leveling material contains a hydraulic binder consisting of cement A having an alite content of 60-70 wt.% and a Blaine specific surface area of 4,000-6,500 cmSP2/SP/g, cement B having a belite content of 35-60 wt.% and a Blaine specific surface area of 3,000-4,000 cmSP2/SP/g, an expansive admixture and a siliceous fine powder having a BET specific surface area of 1-20 mSP2/SP/g, an artificial high-density fine aggregate having a maximum particle diameter of 1.2 mm, an absolute dry density of 2.90 g/cmSP3/SPand a water absorption of 0.90%, and a chemical admixture.
