Ultralow-heat composite cementing material
An ultralow-heat composite cementing material is prepared from, by weight, 0-30 parts of portland cement clinker, 50-80 parts of phosphorus slag, 0-20 parts of limestone, 0-20 parts of coal ash, 0-2 parts of sulphoaluminate cement clinker, 0-4 parts of calcined alunite and 0-10 parts of gypsum. The material has the advantages of having hydration heat of 58-132 kJ/kg in 3 days, the hydration heat of 98-172 kJ/kg in 7 days, the compressive strength higher than 32.5 MPa in 60 days and the compressive strength higher than 50 MPa in 180 days. Due to the characteristics of low hydration heat and high later-period strength of the material, the material is particularly suitable for hydraulic dam concrete with a long construction period and can greatly reduce temperature rise cracks.
