Abstract |
|
|
| This study was conducted to investigate the effect of heavy mineral sand on the compressive strength and workability of ordinary and standard concretes. Concrete mixes were produced by adding heavy mineral sand to fine aggregate with 0%, 20%, 40%, 60%, 80% and 100% percent. Tests on specific gravity, workability and compressive strength were conducted on aggregate and concrete mixes. The results indicate that the compressive strength of concrete is not affected by the increase in the heavy mineral sand percentage. The concrete with heavy mineral sand as a fine aggregate was shown to have very-high workability owing to very fine metals and high surface area. The results denote that the heavy mineral sand improves the surface of concrete. The addition of heavy mineral sand enhances the concrete characteristics. The use of heavy mineral sand is an ingredient that can be used with concrete and leads to significant economic as well as functional benefits.
