The Properties of Mortar for Train Carriage Floor by Effect of Aggregate Types and Composition

The use of oil palm fruit shells, autoclaved aerated concrete flakes, and perlite as aggregates then PVAc as plasticizer in the manufacturing of mortar for train carriage floor were investigated. The objective of this research is to determine the physical and mechanical properties of mortar based on effect of aggregate types and aggregate composition. Mortar was made with weight ratio aggregate : cement : PVAc = 1:1:2 and 1:3:4. Liguid of PVAc were made from weight ratio of PVAc : water == 1:1. Mortar was obtained by mixing cement with aggregate then mixed with PVAc liquid and stir untill evenly mixed. The admixture was putted on 25 mm x 25 mm x 300 mm of mold. After 24 hours, mortar was removed from the mold then further soaked in water for 28 days. Furthermore mortar was physically (moisture content, density), morphologically, and mechanically tested. Mechanical testing was used Universal Testing Machine (UTM) and refers to the ASTM C293-94 standard for flexural strength and ASTM C116-90 for compressive strength. Mortar density was calculated to know the relation within their srength. Proceeding of the 5th International Conference and Exhibition on Palm Oil (ICEPO)
