LIMESTONE CRUSHER-RUN AND TAILINGS IN COMPACTION CONCRETE FOR PAVEMENT APPLICATIONS.

Research output: Contribution to journalArticle

Abstract

Laboratory experiments indicates that both limestone crusher-run and finely grained limestone tailings (by-products of the aggregate mining industry) can be used in concrete made with a emerging technology for flatwork construction known as roller compacted concrete (RCC). This paper reports on tests of laboratory specimens using various combinations of mix components and proportions. The unit cost of concrete progressively decreases as the graded coarse aggregate is substituted with the crusher-run and as the tailings are added. On the other hand, the compressive strength of mixtures including the crusher-run is better than that of graded coarse aggregate and is further improved by the addition of tailings.
