Designing of special concretes for machine building

Based on transdisciplinarity research, using the provisions of the geonics, modern composite materials have been developed that can effectively replace steel parts in mechanical engineering. The composite material was prepared by the joint grinding of cement (55%), ash of acid composition (40%) and limestone (5%) to a specific surface area of 550 kg / m2, with an activity of 70.2 MPa. It was found that the combined effect of mechanical and chemical activation promotes an increase in the pozzolanic activity of acid ash, has a catalytic effect on the reaction activity of the fly ash the Ordinary Portland cement and the limestone crushed waste surfaces during machining in a vario-planetary mill. Thus, in the process of operation of equipment with concrete and reinforced concrete elements, their significant production advantages, determined by the improvement of the precision, strength and other parameters of the machines, due to the use of new materials, will be revealed. © Published under licence by IOP Publishing Ltd.
