Abstract
Re active powder concrete is a type of high performance concrete with low porosity. RPC eliminates the use of coarse aggregates in the mixture to increase compactness, stability of the mixture components, and to minimize internal defects in materials such as void area. Reactive powder concrete is composed by materials such as Portland cement (OPC), quartz sand, quartz flour, silica fume, water, superplasticizer, and without coarse aggregate. The purpose of this research is to analyze the characteristics of reactive powder concrete in density, compressive strength and durability with variation of w/c. This mixture has three variations consisting of variations of w/c. Variations in w/c used were 0.20, 0.23 a nd 0.26 with sulfate immersion for 28 and 56 days. The A STM standard is used as the basis for testing slump flow, setting time, and compressive strength. The result of the maximum compressive strength test is 71.15 N/mm 2 with w/c = 0.20 in the condition without immersion. The result of microstructure test which has the highest C S H and the lowest porosity is w/c = 0.20.
