PENGARUH ZONA PASIR TERHADAP KUAT TEKAN BETON NORMAL

Abstract

This research aims to study the strong press concrete and strong different press concrete using using the sandzone I, zone II and zone IV. As for the benefits of research on society is able to provide the insight of the use of sand onthe concrete mix with respect to sand-grain roughness/smoothness. Gradation of the sand has a roughness/smoothness ofdifferent grains. Based on the large grain of sand (roughness/smoothness) divided in 4 groups of zones, namely sandzone I who has the rough, granular zone II sand with little rough, granular zone III sand with the grain a bit smoother,and zone IV is the sand with the grain smooth. So based on the sand zone created in 3 variants, namely concrete mixconcrete mix that uses sand zone I, using concrete sand zone II, and concrete which uses sand zone IV. The resultsstrongly press the average concrete which uses sand zone I is 28.26 MPa, for the sand zone II was 27.61 MPa, and tosand zone IV is 25.81 MPa. Comparison of strong concrete that use press the sand Zone I against the concrete with sandand concrete zone II yona IV is 94.4% and 91.3%. Thus based on explanation above then mix concrete using coarse gritwill generate strong press value greater than with the use of concrete mix sand with fine granules.
