Abstract

Abstract Effect of Rice Husk Ash of Insoluble Residu, LOI, pH, TDS, Total Hardness and Compressive Strength of Cement Mortar PCC with Sea Water Immersion by: Rike Jayurna (0810413104) Advised by Yulizar Yusuf, MS and Bustanul Arifin, M.Si It had been studied is effect rice husk ash to insoluble residu, LOI, PCC compressive strength of cement mortar and pH, TDS, total hardness of sea water immersion has been done. PCC is a mixture of clinker, gypsum, limestone and pozzolan. The addition of rice husk ash in addition to the utilization of waste is also expected to reduce the use clinker so that production rates could be smaller. Research was conducted to test the compressive strength of mortar is a mixture of cement, water and sand at a certain ratio. Mortar immersed in aquadest and sea water for 3, 7 and 28 days. From the research mortar compressive strength with the addition of rice husk ash 0, 2, 4 and 6% with sea water immersion decrease when compared with aquadest immersion. Insoluble residu and LOI in the cement has increase. On testing the pH, TDS and total hardness immersion solution also increase the variety of rice husk ash but with variation of immersion day decrease of TDS and total hardness. Keywords: PCC, rice husk ash, compressive strength, sea water
