Comparative study on the effect of palm oil fuel ash in supressing the alkali silica reaction for concrete and mortar
Mortar and concrete is widely use in development of research and construction sector. The use of palm oil fuel ash (POFA) in concrete mix is due to the disadvantages that POFA brings by cause some environmental issues also to improve the durability of the concrete. Concrete is expose to Alkali-Silic...

Mechanics of materials Mortar and concrete is widely use in development of research and construction sector. The use of palm oil fuel ash (POFA) in concrete mix is due to the disadvantages that POFA brings by cause some environmental issues also to improve the durability of the concrete. Concrete is expose to Alkali-Silica reaction which can cause defect to the concrete itself by expansion. For this research study, two source of POFA is collected from two different palm oil mills and 2 types of sizes are used, unground size (300 μm) and ultrafine size (below 2 μm). The unground and ultrafine POFA are treated by burning process for one hour and two hour. First objectives for this study are to evaluate the effects of unground and ultrafine size of POFA replacement in suppressing the expansion caused by Alkalisilica reaction.

Mortar and concrete is widely use in development of research and construction sector. The use of palm oil fuel ash (POFA) in concrete mix is due to the disadvantages that POFA brings by cause some environmental issues also to improve the durability of the concrete. Concrete is expose to Alkali-Silica reaction which can cause defect to the concrete itself by expansion. For this research study, two source of POFA is collected from two different palm oil mills and 2 types of sizes are used, unground size (300 μm) and ultrafine size (below 2 μm). The unground and ultrafine POFA are treated by burning process for one hour and two hour. First objectives for this study are to evaluate the effects of unground and ultrafine size of POFA replacement in suppressing the expansion caused by Alkalisilica reaction. Second objectives are to evaluate the effects of unburnt and burnt POFA as cement replacement in suppressing the expansion caused by Alkali-silica reaction. Last objectives are to analyze and investigate the correlation between mortar bar test and concrete prism test. Two accelerated tests are conducted in this research, ASTM C1260 for accelerated mortar bar test and RILEM AAR-4.1 for accelerated concrete prism test. Based on the result from the tests conducted, ultrafine POFA and burnt POFA (two hours treatment) is more effective in suppressing the expansion caused by Alkali-silica reaction. |
