Abstract

This research aimed to determine the effect of aggregate nypa trunk particles composition and the addition of CaCl2 accelerator in physical and mechanical characteristics of lightweight concrete-block. The testing procedure was performed based on ASTM C 90-09 standard for oven-dry density test, water absorption, and compressive strength. The results showed that the difference of nypa trunk particle composition in lightweight concrete-blocks mixture influenced the oven-dry density, water absorption, and compressive strength values of lightweight concerete-block, otherwise the addition of CaCl2 accelerator in lightweight concrete-block mixture has no effect on oven-dry density value, water absorption and compressive strength. The larger of the nypa trunk particles composition in the lightweight concrete-block mixture obtain lower oven-dry density, higher water absorption, and lower compressive strength. The lightweight concerete-block from aggregate of nypa trunk particles in this research did not qualify ASTM C 90-09, because water absorption and compressive strength values were not eligible.
