Studying fiber­reinforced concrete for casting housing parts of pumps

Abstract


Many enterprises of the mining and metallurgical industry use pumps transferring aggressive liquids and slurries containing abrasive particles. For the manufacture of pump housings, taking into account their operating conditions, expensive alloy steels with increased wall thickness are used.

As a result of the study, the analysis of possible materials for the manufacture of fiber-reinforced concrete with the required strength characteristics was carried out. The selection of the optimum ratio of the components, providing, on the one hand, cost minimization of fiber-reinforced concrete and, on the other hand, rational technology for the manufacture of housing parts of fiber-reinforced concrete without additional machining, was carried out.

It was found that the specified conditions are met to the greatest extent by the mixes containing crushed rubble, quartz sand and ground quartz as aggregate, anchor steel fiber, as well as resin and hardener.

Theoretical and experimental studies showed that the aggregate must meet the following requirements: it must be three-component by particle size distribution, and the particle size of each component must differ by an order of magnitude from the previous one. This allows obtaining dense mixes by filling voids in large fractions with smaller particles.

As a result of laboratory studies, it was found that the compressive strength of such hardened mixes is 230...240 MPa.

It was found experimentally that the optimum fiber additive (steel anchor) should be within 3...5 % by weight.

The results of the study allow carrying out calculations of the parameters of pump housing parts with reduced wall thickness, lower weight, and also developing a technology for casting such parts with a high degree of readiness for use
