“…In order to overcome these shortcomings and increase activity of main components, various approaches have been developed to create new types of low-emission cements. Significant acceleration of hardening of cement systems can be achieved by nanomodification and alkaline activation [8][9][10][11]. The reduced clinker factor of multi-component cements determines low heat of hydration of concrete which ensures their effective application in massive structures.…”

“…Possibility of utilization of industrial wastewater in production of safe building materials on AAC basis has also been shown [7]. Such cements are characterized by high heat-resistance [8], corrosion resistance [9] and freeze/thaw resistance [10] in comparison with those based on conventional clinker cements for general and special construction purposes.…”

“…Authors of [17,18] note that one of main approaches to acceleration of concrete hardening consists in increasing specific surface area of composite cements and density of particle packing by introducing water-reducing admixtures. On the other hand, effect of accelerating early strength gain can also be achieved by alkaline-sulfate activation [19][20][21]. Presence of active mineral additives (granulated blast furnace slag, natural pozzolan and fly ash) in the cementitious matrix of concrete when adding an alkaline-sulfate hardening activator ensures exchange reaction and formation of structurally active AF m phases.…”
