Light fine-grained fibrous concrete for small architectural forms

Abstract

The selection of the composition of a highly mobile concrete mixture for manufacturing small architectural forms has been performed, and the strength characteristics of light fine-grained fibrous concrete have been studied. It has been experimentally established that the optimal ratio of the Portland cement to microsilica is 1: 1. The introduction of basalt fiber in the amount of 0.5% of the mass of solids contributes to the increase in bending strength of fine-grained concrete to 70%.

Light fine-grained fibrous concrete for small architectural forms

“…It can be seen from Table 2 that an increase in the amount of microsilica in a concrete mixture leads to a decrease in the mechanical characteristics of fine-grained concrete. The introduction of 10% of the mass of solid components into the composition of chalk MTD-2 makes it possible to increase the compressive strength of concrete by 4÷19% and the bending strength by 7 ÷ 42.5%; with the addition of chalk CALCITEC V/40S, the compression ratio was from 1 to 8% and with bendingfrom 11 to 32.5% [23].…”
