CHAPTER THREE
3.0 Materials and Methods
3.1 Materials Selection
The materials used for the study of compressive strength of concrete partially replace with bamboo leaf ash are; Coir ash, coarse aggregate, fine aggregate and cement.
3.1.1 Coir ash:
The leaf was obtained mostly behind stream. In this research the bamboo leaf were obtained at Alagbado, Ilorin in a cold area as shown in plate 3.1. The leaf were then air dried for few days and burnt in a local pot at about 3800 and in an open space, uncontrolled burning process in which the leaf turned into ash (black in color) as shown in plate 3.2. The quantity and fineness of BLAsh was improve, by grinding until the median particles sizes were 225 microns as shown in plate 3.3
This show in plate 3.1.

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 TWO - [ Total Page(s): 5 ]Mineral admixture in cement and concrete focuses on how to make more workable and durable concrete using mineral admixtures.Improve resistance of concrete to thermal cracking alkali – aggregate expansion and sulphate attack; and to enable a reduction in cement content.These are;(i) Bamboo leaf ash (BLASH)(ii) Fly Ash(iii) Blast furnace slag (BFS)(iv) Rice husk Ash (RHA)(v) Silica fume(vi) Metakaolin (Oyekan, 2007) 2.2 BAMBOO LEAF ASHBamboo are gro ...

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---
