INFLUENCE OF THE MODIFIED MINERAL ADDITIVES ON STRENGTH PROPERTIES OF FINE-GRAINED CONCRETE
Description
In the article we have presented the results of research of influence of activated mineral fillers on mechanical properties of fine-grained concrete. It is shown that clay and zeolites in mechanical activated condition have increased both early and estimated durability of concrete

INFLUENCE OF A WAY OF CRUSHING ON ACTIVITY OF INGREDIENTS OF CONCRETE MIX
Description
The article presents the results of the researches of the influence of a way of crushing on activity of ingredients of concrete mix. It is shown that sand crushing by method of free kick in a planetary mill of AGO-2 allows not only to raise its specific surface, to receive the demanded particle size distribution, but also to improve quality of a surface of particles by removal, destruction of superficial inactive films. On a new surface of sand excess energy concentrates, the active centers are formed and there is a fixing of germs of new growths of products of hydration of cement in a place of an exit of dislocations to surfaces of crystals of sand that leads to substantial increase of chemical activity and reactionary ability of sand

Description
Experimental data on research of influence of technological parameters on structure and durability at compression of the modified fine-grained concrete are presented in the article. It is shown, that at the optimum maintenance of a mineral additive as a part of the mixed knitting the optimum capillary and porous structure of a cement stone and the increased volume of hydrate new growths is formed. At the raised volume maintenance of an active mineral additive there is a formation of the non-optimal capillary and porous structure of a stone leading to decrease in efficiency of modifying

MECHANICAL ACTIVATION PROCESSING OF A FILLER FOR FINE-GRAINED CONCRETE QUALITY IMPROVEMENT
Description
The results of research of influence of mechanical activation of filler (river sand) on physical, mechanical and structural properties of fine-grained concrete are presented in the article. The prospects of using mechanical activation technologies for production of concrete with the improved complex of technical characteristics are established

PROPERTIES OF THE FINE-GRAINED CONCRETE RECEIVED AT NEGATIVE TEMPERATURES
Description
Researches of fine-grained concrete testify the possibility of using mineral mechanically activated and nano-additives in a complex with the anti-frost additives providing the organization of production of concrete works at negative air temperatures that is especially important for the Arctic regions
