Abstract
The using additive for concrete mixing has developed recently aim to increase the behaviour and
compression strength of the concrete. Silica presipitated is one of additive materials used for
concrete mixing. It's obtained from the crude palm oil industrial process. On this research, silica
presipatated will be added by using comparison 0%, 4%, 8%, 12% of cement weight. According to
this research, concrete compression strength increase 9,77% with addition 4% silica presipitated
of concrete 0% silica presipitated at age 28 day. Modulus elasticity also increase 2,02% on adding
4% silica presipitated of concrete 0% silica presipitated at age 28 day
