“…Tkaczewska 36 studied the effect of the type of superplasticizer on y ash blended cement and concluded that the water requirement for the reaction was reduced and the hydration heat, setting time and the mechanical properties improved. Kaja et al 22 studied the effect of Portland cement addition on improvement in reaction kinetics and setting time of class-F y-ash geopolymer cured under ambient conditions. Zhang et al 35 studied that due to grain size re nement and pore size re nement, the setting time of ternary blended cement was decreased and, both late and early age strength was increased considerably.…”

“…Furthermore, the addition of y ash decreases the amount of water requirement for setting of cement, high ultimate strength, improves the workability, reduces bleeding, reduces heat of hydration, reduces permeability, increases resistance to sulphate attack, increases resistance to alkali-silica reactivity, lower costs, reduces shrinkage, increases durability [16][17][18][19][20][21][22][23][24][25][26][27][28]. Hence, it can be said that the use of y ash in the cement will enhance the properties of cement, particularly, in increasing the strength, leading to cement with longer durability and strength.…”

“…OPC is another calcium resource often adopted in FAAMs. It was proved that the replacement of fly ash with OPC could effectively improve the strength of FAAMs from the early age to the final days [137][138][139][140]. In an FAAM activated by a modified alkaline activator, by adding a silica fume to the sodium hydroxide solution, as the 15 % OPC replaced the fly ash, the early compressive strength at 1 day was ca.…”

“…The results show that strength to compression of this cement made up from 33.25 to 51.38 MPa. It grows at an increase in the amount of introduced Portland cement [8][9][10][11][12][13][14][15].…”
