dc.description.abstractThis research aim was to made ecocement using ash shells as the main raw material. Ash shells derived from waste shells of sea shells (Anadara grandis) and were burnt at the temperature of 7000C. The contain of calcium oxide (CaO) was 55,10% expected to replace lime as the main raw material in the manufacture of cement. In this research, ecocement were made with variations A 100% ash shells and variations B 50% ash shells : 50% lime. The main raw material is mixed with other ecocement ingredients (SiO2, Al2O3, Fe2O3, and MgO) and burnt at a temperature of 14000C to obtain clinker. Further, clinker was added with gypsum to produced ecocement. The results of chemical characteristics of ecocement A were insoluble : 0,36%, SiO2 : 20,26%, Fe3O2 : 3,46%, Al2O3 : 6,42%, CaO : 63,16%, MgO : 1,67%, SO3 : 2,76%, lost incandescent : 1,82%, alkali 0,56%, free lime : 1,22%, C3S : 42,20%, C2S : 26,20%, C3A : 11,20%, and C4AF : 10,52%. In ecocement B were insoluble : 0.67%, SiO2 : 21,09%, Fe3O2 : 3,63%, Al2O3 : 5.96%, CaO : 63,25%, MgO : 2,05%, SO3 : 2,77%, lost incandescent : 1,31%, alkali 0,50%, free lime : 1,30%, C3S : 38,80%, C2S : 31,20%, C3A : 9,70%, and C4AF : 11,0%. The results of testing the chemical characteristics of the two ecocement were appropriate with SNI 15-2049-2004. The results of compressive strength testing of mortar at 28 days showed that sample A had 171 kg/cm2 and sample B had 196 kg/cm2. The results of testing the physical characteristics of the two ecocement were not yet appropriate with SNI 15-2049-2004.en_US
