| Summary, etc. |
In this paper, the effectiveness of fly ash (FA) and ground granulated blast-furnace slag (GGBS) in controlling the heat of hydration, strength, and durability of mass concrete is presented. For this purpose, five concrete blocks having dimensions of 0.9 × 0.9 × 0.9 m were cast with varying proportions of cement, FA, and GGBFS. The rise in temperature with the increase in hydration time was measured by Type-k thermocouples. The compressive strength and rapid chloride permeability test (RCPT) were measured by extracting the cores of size 103 mm diameter with two different heights (200 mm height for compressive strength test and 50 mm height for RCPT test) from the centre of the blocks. Analysing the results, it is noted that the use of 20 and 35 % FA lowered the peak core temperature by 7.7 and 15.4 %, respectively, and enhanced the strength of cores by 29.7 and 36.1 %, respectively, at 56 days of curing than the 100 % ordinary Portland cement-based sample. Similarly, the use of 50 and 70 % GGBS lowered the peak core temperature by 11.5 and 17.3 %, respectively, and enhanced the core strength by 31.1 and 29.1 %, respectively. This is attributed to the lower amount of evolution of heat at the early age and the increase in homogeneity of hydrated products and refinement of pores of the FA and GGBS-based samples during secondary hydration reaction at higher curing temperatures. The utilization of FA and GGBFS will not only reduce the peak core temperature and enhance the strength, but also improve the durability of mass concrete. |
