A Study of Composite Concrete Using Palm Oil Fuel Ash (POFA) as a Partial Replacement for Cement in Self Compacting Concrete

Due to its flexibility at young ages and its capacity to be moulded into any necessary structural form and shape, concrete is the most commonly used construction material. For concrete to be workable and to have the necessary strength and durability, thorough compaction utilising vibration is typically necessary. Large numbers of voids are caused by inadequate concrete compaction affecting the structural strength and long-term toughness. Self-Compacting Concrete (SCC) offers a remedy for these issues. As its name suggests, it may compress itself without the need for additional vibration or compactive force. The lack of standardised mix design procedures and testing techniques has, however, limited the scope of applications for self-compacting concrete. Because there is no need for vibration and noise pollution, self-compacting concrete is becoming more and more popular. Using Ordinary Portland Cement, Palm Oil Fuel Ash as a mineral additive, and Polycarboxylate Ether as a super plasticizer, the study investigates the performance of self-compacting composite concrete. Palm oil fuel ash is substituted for cement in varying amounts (0%, 5%, 10%, 15%, 20%, and 25%). The results of the slump flow test, V-funnel test, and L-Box test for the acceptance characteristics of self-compacting concrete are provided. For M30 grade concrete, compressive strength at 7 and 28 days of age is also calculated. This document also includes the test findings that were collected.
