مستخلص: | This study was dedicated at design of alkali-activated (slag) cements with high-modulus soluble silicates and concretes based on them which would possess workability retention, quick and steady strength gain, high strength characteristics, etc. Specific features of mode of deformation (in tension under bending stresses) of fine aggregate alkali-activated cement concretes were studied. The results of this study showed that the modified alkali-activated cements and concretes exhibited high tensile strength in bending and high ratios of this strength to compressive strength. The results of analysis of deformation of the alkali-activated cement concretes under action of bending stresses showed that high values of crack resistance, impact resistance and increased deformability could be expected. Basic strength and deformation characteristics of the developed repair mortars and concretes after additional optimization of their constituent composition are provided and discussed.
