The article examines the use of unmanned complexes for finding and identifying defects in the construction of buildings and structures. The use of unmanned complexes integrated into practice for quality control of construction works of concrete and steel surfaces, as well as for regular inspections of buildings, insulation or ventilation systems is given. The prospects of using unmanned complexes for repair work, which contributes to improving the performance of the construction organization, were confirmed.

The article presents a study of the hydrophysical properties of modified cement concretes, namely frost resistance and water resistance. The compositions of modified concretes for research are determined. It is established that the use of mineral fertilizer production waste in combination with the superplasticizer "Osnovit Safescreen SPP1" allows to increase the frost resistance, water resistance and strength of concrete composites.
