Item Evaluation of basalt fiber for strength self-compacting concrete(Видавництво Львівської політехніки, 2013) Stechyschyn, MykhailoThe effect of basalt fiber on the properties of cementing systems based on portland cement using active mineral additives microfillers and complex chemical additives for self- compacting of concrete.Item Self-Compacting Concrete mechanically activated on Portland cement with the addition of ground hydrated cement(Видавництво Львівської політехніки, 2013) Barabash, I. V.; Bystrevskyy, K. S.The paper deals with the influence of ground hydrated cement (GHC) on the change in the strength characteristics of self-compacting concrete. It is found that the addition of hydrated cement binder can accelerate the process of curing concrete in the early stages of hardening, as well as to increase the strength of the vintage age.Item Peculiarities of structure formation processes in nonautoclaved aerated concrete produced using industrial wastes(Видавництво Львівської політехніки, 2013) Melnyk, AndryFollowing the strategy of sustainable development and the principle of applying the best available technologies, energy saving in Ukrainian Housing and Public Utilities Sector is achieved by constructing energy efficient buildings due to applying efficient building materials. Development of modern building technologies in all technologically advanced countries is aimed at developing cost-effective, efficient materials the use of which can reduce energy costs and consumption of raw materials. Aerated concrete is the optimal material for housing because it has wide density and durability range, the properties being important for solving various structural problems. The aerated concrete based on the modified cementitious system containing an additional cementitious material, that of carbonate-bearing salt waste is characterized by the compressive strength of 2.7 MPa with the density of 650 kg/m3 after 28 days of hardening.
