    • ABSRACT - [ Total Page(s): 1 ]ABSTRACTUtilizing Palm Oil Fuel Ash (POFA) in concrete mix is a major way of turning waste to wealth. Gravel as an aggregate is cheaper than granite. Thus, obtaining an optimum combination of these materials in achieving a maximum compressive strength in concrete will go a long way in helping the construction industry.The study was carried out to establish an optimum replacement ratio for Palm Oil Fuel Ash (POFA) blended granite-gravel of concrete. Uniform water/binder (w/b) ratio of 0.5 and mix ... Continue reading---

      CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 Background of the study        Concrete is regarded as the primary and widely used construction ingredient around the world in which cement is the key material. However, large scale cement production contributes greenhouse gases both directly through the production of CO2 during manufacturing and also through the consumption of energy (combustion of fossil fuels). Moved by the economic and ecological concerns of cement, researchers have focused on finding a subs ... Continue reading---

         

      CHAPTER TWO - [ Total Page(s): 9 ]However, POFA contribute to its long-term strength due to the continuous pozzolanic reaction because of the fine particle size, the greater glassy phase of SiO2 and the reduced composition of carbon (Zeyad et al., 2012). This is also proved by Altwair et al. (2011) using the strength activity index which is the ratio of the strength of SCM-cement mortar to cement mortar at specific curing time. 2.3 Ultrasonic Pulse Velocity (UPV) of Concrete with Replaced POFA      According to Kanadasan & ...

      CHAPTER FOUR - [ Total Page(s): 15 ]Figure 4.2 shows effect of granite and POFA mix ratio on compressive strength of concrete. The graph shows that, the increase in granite volume led to increase in compressive strength. However, increase in POFA percentage led to decrease in compressive strength. It can be observed that, the highest compressive strength was achieved at 25% POFA replacement and lowest at 35% replacement. Also, for granite highest and lowest compressive strength were achieved at 100% and 0% replacement respectively ... Continue reading---

         

      CHAPTER FIVE - [ Total Page(s): 1 ]        CHAPTER FIVECONCLUSION AND RECOMMENDATIONS5.1    Conclusion The study determined the compressive strength of granite-gravel concrete at varying replacement of Palm Oil Fuel Ash (POFA) at different curing ages. Also, established an optimum replacement of Palm Oil Fuel Ash (POFA) blended granite-gravel. Therefore, the following conclusions were drawn:1.    The increase in granite volume led to increase in compressive strength. However, increase in POFA percentage led to decrea ...
