Physical and Mechanical Properties of Cement/Natural Rubber Latex/Rice Husk Ash Composites

Abstract:

The microstructure and mechanical properties of Portland cement (PC)- natural rubber latex (NRL)- rice husk ash (RHA) composites have been investigated. The proportions of PC-NRL-RHA composites with NRL to cement ratio (NRL/C) that use in this experiment were 0, 0.10, 0.15 and 0.20 respectively. Portland cement (PC) was partially replaced with rice husk ash at 20% by weight of binder. The rice husk ash (RHA) was ground for 180 minutes before using. Water to cement ratio (W/C) equal of 0.5 by weight not include water in NRL. Nonionic surfactant was added in cement before mixed with NRL. In addition, to provide latex from natural rubber, the ammonia solution is added into natural rubber. The specimens were casting in standard mold which samples size of 50x50x50 and 40x40x160 mm³ respectively. Moreover, the PC-NRL-RHA composites were cured in water for 3, 7 and 28 days at room temperature before measurement. Then, mechanical properties (compressive strength and flexural strength) and microstructure were studied.
