Abstract:Engineered cementitious composite (ECC) is a composite that has better tensile properties and behavior compared to concrete. ECC is usually made from cement, water, silica sand, cementitious material, fiber, and other materials. ECC mortar does not use fiber. Cementitious material in this research uses palm shell ash, with a proportion of 5-15% of the cement weight. Crumb rubber was used as a substitute for fiber, with a proportion of 2.5-12.5% of cement weight. Workability is measured based on the slumpflow t… Show more
