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 partial replacement for cement in ranges of 5%, 10% 15%. Strength and durability tests were carried out t

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0Â Â Â INTRODUCTIONÂ 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 aggregate surface. With most natural aggregates, it is possible to make concrete up to 120KN/mm2 a compr ... Continue Reading

CHAPTER THREE - [ Total Page(s): 15 ]From the grading curve;WhereThe effective size at 10% percent passing through = D10The effective size at 30% percentage passing = D30The effective size at 60% percentage passing = D60Therefore, D10=0.25um; D30=0.840um, and D60=0.8umCoefficient of uniformity (Cu) = D_60/D_10 = 0.8/0.25 =3.2Coefficient of curvature, Cc = ((D_30)2)/(D_10Â x D_60 )=0.5402/0.25x0.8=1.46REMARK: based on the result, the F.M of the sand is 3.1.i.e. coarse sand, coefficient of uniformity is 3.2 and coefficient of curvature is 1.46 respectively and according to the grading, the sand is well graded. ...

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 concrete will be workable but not as cement which is in correspondence to (ASTM C 143 or EN 12350).â ... Continue Reading
