Artificial sand, Stone dust, Slump test, Compressive strength, Workability of concrete.
Common river sand is expensive due to excessive cost of transportation from natural sources. Also large scale depletion of these sources creates environmental problems.The study was conducted to evaluate workability and the strength characteristics of concrete with variable dust percentage in artificial sand. The concrete mix design was done for M25 grade concrete. The mix is prepared for natural and artificial sand containing dust varying from 0%, 10%, 20% to 30%. The concrete mix properties were studied in fresh and hardened state for that slump cone test
The study was conducted to evaluate the strength characteristics of concrete with variable dust percentage in artificial sand. The concrete mix design was done for M25 grade concrete. In this study dust which is a waste material stone crusher plant was used as a additive in artificial sand and the concrete made by using artificial sand with 20 % dust were found to be satisfactory. The workability of concrete made by using artificial sand with dust as additive was found greater than natural sand made concrete.
