hand, the quarrying of raw materials is becoming difficult. The present work presents the results of experimental investigations carried out to evaluate the effect of partial replacement of cement, fine aggregate and coarse aggregate by different parts of demolished wastes .
Aggregates | Difference Between Coarse And Fine | How to ...
Aggregates: Aggregates are inert granular, substances like either sand gravel or crushed stone which are an important component in concrete, alongside water and portland cement.. Aggregates must be pure, hard, solid particles free from ingested chemicals or adhesives of clay as well as other fine materials for a good concrete mix that could trigger the concrete to deteriorate.
RECYCLED TIRES AS COARSE AGGREGATE IN CONCRETE
tire chips can be used to replace coarse aggregate in concrete pavement mixtures. Two mixtures with 10% coarse aggregate replaced by tire chips and normal cement content had the best performance. The workability was comparable to the control mixture, and the air content reached 6%.
