| dc.description.abstract | Manufactured sand is the best alternative material to replace natural sand in concrete making. The study found that the quality of manufactured sand produced from quarry dust was improved after crushed in Barmac VSI Crusher with different of rotor speed and was suitable to used in concrete. The study involves Yen Bumi quarry dust and natural sand as comparison. The control variable was rotor speeds of 40 Hz, 50 Hz and 60 Hz with 0% cascade flow ratio and feed rate 18.73 t/h. Concrete that been produced using crushed product had achieved high compressive strength with 50.83 N/mm2 after 28 days. The quality of products was analyzed through particle size, particle shape, silt content test, clay content test, void content test and flow cone test. The lowest void content percentage was showed at product of rotor speed 60 Hz with 45.80% for flow cone test whereas 44.29% and 38.18% for uncompacted and compacted void content test at rotor speed of 50 Hz. The lowest flow time recorded was 27 seconds. The highest silt content in the products was 14.71% which still below acceptable limit. The particle shape produced was nearly rounded and uniform in shape for product of rotor speed of 50 Hz. The result obtained from the analysis showed that product produced by Barmace VSI Crusher had improved and will produced better quality of concrete compare to natural sand. As a conclusion, manufactured sand with produced by using suitable process and cost adjustment able to replace natural sand in concrete making industries. | |
