Abstract

Concrete is kind of material which have effectiveness to do something, used simple building construction or complex building construction. Concrete material is consist of cement as a glue, agregat of soft sand, rough sand (gravel) and water. Agregat takes 70 – 75 % of concrete volume total.So the quality ofagregat will strong influence to concrete quality. By a good agregat, concrete can be easy done ( workable ), strong, durable and economical.Soft agregat (sond ) generally 25 - 65 % agregat total volume. We must be careful to choose sand prosentage to agregat total. Too small sand can produce segrega tie concrete, because of more rough agregat. Too much sand which is used can produce low solid. Commonly the sand which is used for mixed for concrete is Muntilan sand, but there is some one who use Cepu sand. From the both ofthe sand after had been tasted produced date of volume mechanic difference (strong pressure, strong pulling, strong curve ) conrete which is used Muntilan sand is higher quality than Cepu sand, but mud prosentage Muntilan sand is higher than mud Cepu sand. It is possibility Muntilan sand rougher than Cepusand or surface of Cepu sand is less sharp. So must do experiment at next time.Keywords : Muntilan sand and Cepu sand, concrete mechanic volume
