Feasibility Study on use of Copper Slag in Cement Concrete and Mortar
Client : Sterlite Industries Limited, Tuticorin, Tamil Nadu Period: April 2009-December 2009
- Effect on compressive strength of M25 and M40 grade concretes with 25%, 50% and 100% replacement of conventional river sand with copper slag (CS)
- Test for plasterability of CS based cement mortar on brick surface
- Evaluation of CS based cement mortar as a joining material for use in brick masonry construction
Benefits
- Increase in density up to 19%
- Workability is improved
- Compressive strength is increased
- With 100% replacement slight bleeding tendency
- Copper slag – Plastering of floorings and horizontal surfaces up to 50 % by mass
- his can be reduced up to 25 % by mass for vertical surfaces
- Copper slag is not suitable for use in ceiling plaster
- Generally, fine aggregate passing 2.36 mm sieve is suitable for plastering
