4.5 Discussion of Result
Table 4.1 shows the slump test result that the degree of workable of bamboo leaf ash in concrete, can be observed that the slump value decreased with increase in bamboo leaf Ash percentage. This implies in table 4.1 that the concrete become less workable (stiff) as the bamboo leaf Ash content increased. It is observed from table 4.13 that compressive strength decreases with increase in percent of bamboo leaf ash. The compressive strength of BLAsh 5, BLAsh 10, BLAsh 15 and BLAsh 20 was lesser that of control mix.
Table 4.8 show the effect of curing on the concrete was revealed through density test, this implies that bamboo leaf Ash has no significance effect on the density of the concrete comparatively. This strength develop is believed to continue as long as the curing period show in Plate 3.6 is prolonged to allow hydration process to be complete. The strength value of different ages for 5%, 10%, 15% and 20% BLAsh replacement are inferior when compared to the control of 0% BLAsh replacement, the optimum compressive strength of 20.00 N/mm2 was obtained at 5% replacement at 28% of age in respect to the 20.00N/mm2 compressive from (compressive strength of concrete classes 14-35).

ABSRACT - [ Total Page(s): 1 ]ABSTRACTConcrete is a major construction material, which is usually made by mixing cement, water, fine and coarse aggregate and sometimes admixtures in their right proportions. The use of waste materials with pozzolanic properties in concrete production is a becoming a worldwide practice. The assessment of the pozzolanic activity of cement replacement materials is becoming increasingly important because of the need for more sustainable cementing products. In this bamboo leaf Ash is used as parti ... Continue reading---

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0 INTRODUCTION Concrete is a composite element consisting of aggregates enclosed in a matrix of cement paste including possible pozzolanic, has two major components-cement paste and aggregates. As a construction material, concrete can be in almost any shape desired, and once hardened, can become a structural (load bearing) element. The strength of concrete depends upon the strength of these components, their deformation properties, and the adhesion between the paste and aggr ... Continue reading---

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.0 CONCLUSION AND RECOMMENDATION5.1 CONCLUSIONBased on the experimental investigations carried out and results obtained, it is therefore concluded that;• The suitability of using bamboo leaf ash BLA as supplementary cementatious material has been explored.• The compressive strength or ability of fresh bamboo leaf ash content measured by the slump test reduces as the bamboo leaf ash content increases. It is therefore noticed, that bamboo leaf ash c ... Continue reading---
