Abstract

Photocatalytically active fine-grained concrete has been developed using a titanosilicate additive, which is a waste product from the production of titanosilicate sorbent. It has been established that the introduction of a titanosilicate additive into the composition of fine-grained concrete ensures the formation of an additional amount of calcium hydrosilicates, mainly low-basic ones, increases the density of the cement stone and reduces structural defects, thereby facilitating the production of higher-strength concrete with improved technical and operational properties. For the developed concrete composition containing 2% (by weight of cement) titanosilicate powder, 1.1 wt. % Glenium 51 superplasticizer, with a W/C of 0.42, an increase in compressive strength by 52% and a decrease in water absorption by 32% were recorded, reducing the depth of wear and weight loss by 35%, increasing frost resistance by 3 grades, compared to the additive-free composition. The surface of fine-grained concrete containing waste titanosilicate sorbent, in the decomposition reaction of methylene blue, exhibits the ability to self-clean under the influence of visible light, and under ultraviolet light it exceeds samples with commercial titanium dioxide. Also, the manifestation of the self-cleaning ability of modified concrete is confirmed by a decrease in the contact angle during irradiation with ultraviolet light.
