·The outcome from their research work clearly indicated that ternary blend was superior than binary blend in terms of performance Dhinakaran et al [42] compared the strength and durability of High Performance Concrete HPC in 3 different forms viz with mineral admixtures GGBS and Quartz powder air entraining agent and light weight aggregate
·The present study focus on the fatigue behavior of conventional concrete and high performance concrete The conventional concrete M30 grade with mix ratio of 1 designed as per IS44
·The seawater mixing improved the strength development to increase the 28 and 91 days STS of HPC containing GGBS The accelerating effect is caused by the reactions between Cl and SO 4 2 ions in seawater and Al rich phases of GGBS [51] The alkaline environment also provides favourable conditions for the pozzolanic reactions
·Incorporating industrial by products into the manufacturing of geopolymer concrete has the potential to make concrete production more environmentally sustainable This research employs ground granulated blast furnace slag GGBS and dolomite as alumino silicate base materials and sodium hydroxide solution NaOH and sodium silicate solution Na2SiO3
·In contrast the relative dynamic modulus evolution for the HPC P•HSRF S group which contains GGBS shows a significant shift to the right during freeze thaw cycles with a lifespan far surpassing that of the HPC P•HSRF F group ranging from 460 to 688 cycles Since both groups used the same type of cement PHSR with the only differences
