Technology for improving the wear resistance of aggregates by materials impregnation
Abstract
Tests performed to evaluate the effect of impregnation on the physical, mechanical, wear resistance and polish resistance properties of the aggregates included: petrographic analysis, Los Angeles abrasion loss, sodium sulfate soundness loss, the British polish wheel, aggregate surface microtexture analysis, and two circular test track studies. Impregnants studied included: MMA based and styrene based monomer systems, water based phenol formaldehyde resin, and sodium silicate. In general, it was found that the physical and mechanical properties of natural aggregates can be significantly improved by impregnation. Significant improvements in wear resistance can also be obtained, however, in some instances, this improvement is accompanied by a decrease in polish resistance.
