Abstract: This paper studies the effect of high temperature curing method on the compressive strength of high content ground blast furnace slag concrete. GGBS is used to replace Portland cement with a replacement rate of 60 of the mass of binder. The high temperature curing parameters used in this study are delay period, heating, peak temperature (PT), peak period and cooling. The test results show that after 1 day, the compressive strength of samples with PTS of 65 ° C and 75 ° C is about 88 higher than that of samples with PTS of 55 ° C. According to this investigation, there may be the best high temperature curing conditions for preparing concrete containing a large amount of GGB and adding GGB to precast concrete mixtures can be a very effective tool in increasing the applicability of this by-product.
