In this study, the results of experiment research on building mortars based on dry mixtures with the use of granite dust are given. It also shows the possibilities of their industrial release. In the conditions of energy resources shortage, gradual exhaustion of natural raw materials, aggravation of environmental problems, an important direction in the production of building mixtures is the development of mixes with waste materials from various industries. In particular, granite dust, which simultaneously allows to rationally use natural mineral material and solve environmental problems. Based on the obtained data, experimental and statistical models of physical and mechanical properties of fresh and hardened mortar are constructed and ways of optimizing their compositions and improving the properties of mortars are analyzed. It is established that the use of granite dust and some additives provides high standardized parameters for mortar mixture and bricklaying process, including plasticity, compressive strength and others at the low level of cement consumption. Fresh mortar mixtures have a prolonged slump retention.

For the decreasing of too high air volume in SCC, application of anti-foaming admixture (AFA) is proposed. In effect, AFA is increasing mix flow diameter and decreasing the flow time. Moreover, the workability loss is lower. In case of mix incorporating AFA, their high fluidity do not generate segregation of the mix, which is possible in case of SCC incorporating only SP. The effect of AFA application on the compressive strength depends on the proportions between SP and AFA. AFA has not a negative influence on the freeze-proof properties of the tested concrete. The advisable influence of AFA on porosity characteristic of SCC is proved by research results according to EN 480-11 code.
