• low-heat portland cement
• mass concrete
• high crack resistance
• moderate-heat portland cement

The properties of low-heat Portland cement concrete(LHC) were studied in detail. The experimental results show that the LHC concrete has characteristics of a higher physical mechanical behavior, deformation and durability. Compared with moderate-heat Portland cement(MHC), the average hydration heat of LHC concrete is reduced by about 17.5%. Under same mixing proportion, the adiabatic temperature rise of LHC concrete was reduced by 2 degrees C-3 degrees C,and the limits tension of LHC concrete was increased by 10 x 10(-6)- 15x 10(-6) than that of MHC. Moreover, it is indicated that LHC concrete has a better anti-crack behavior than MHC concrete.
