Abstract

ABSTRACT The Effect of Grinding Aid (IH G4, IH G2 Dan Estop) Intercalation Toward The Physical Properties and The Chemical Properties of Cement Type I By: Celsynthia Fiana (1310411063) Yulizar Yusuf M.S*, Prof.Dr.Hermansyah Aziz* *Advisor The manufacturing process of cement and it’s quality is depend on of process and the use of additivies. Grinding aid is one of additivies compound that added into the clinker before grinding process in order to increase the fineness of cement to become faster and optimum. Based on this work, the chemical composition of cement type I which has with additivies the grinding aid not provide a much more distinguish change comparing without grinding aid additivies. Only fineness of cement that increases, the rest on the sieve test was decrease. The cement which has the value that already known was mixed the sands and water to form a dough and it’s mould. The mixture was the analyzed to determine the compressive strength. The increasing of fineness value cement due to the decreasing of the rest on the sievie test and the compressive strength value was observed. The compressive strength value of the cement type I which was with additive of grinding aid was increases and agreed by the requirements the cement specification of Singapore Standart. Keyword : grinding aid, fineness, compressive strength, cement type I, Singapore Standart.
