Compressive strength of Portland blast furnace slag cement concrete in adiabatic and semi-temperature matched curing conditions

Yang, J.L. / Chen, E.Y. / Low, G.L. / Tan, B.T.

Various grades of Portland blast furnace slag cement (PBFC) and normal Portland cement (OPC) concrete have been cured under adiabatic and semi-temperature matched curing conditions. Comparisons of the compressive strength between adiabatic, semi-temperature matched and ambient cured concrete have been made. The results indicated that the curing history had significant influence on the compressive strength development and the in-situ early strength of PBFC concrete is comparable to the same grade of OPC concrete after three days. The high curing temperature (above 65 deg C) reduced the later-age strength both for PBFC and OPC concrete. The durability of the concrete cured under various conditions was also evaluated by rapid chloride permeability test.
