3.2.4 CASTING
Casting was done by placing the already mixed concrete in the mould made for the casting. All ingredients were hand mixed properly using the shovel and hand trowel. The concrete mixes and the specimens were prepared in accordance with the provisions of BS 1881 – 125 standard. Mould of 150mmx 150mm x 150mm size (steel moulds) were used, cleaned and smeared with oil before filling with concrete. The fresh concrete workability was investigated immediately after the final mixing of the concrete using slump cone. The cubes were then casted used to level the surface of the cubes. as shown in the plate 3.5
3.2.5 COMPACTION
Compaction is the process of expelling the entrapped air. If air is not expelled, it will result into honey combing and reduced strength. The hand method of compaction was used to avoid voids and ensure proper compaction with a steel rod by tamping. 35 blows were used during the compaction of the concrete after which the surface of the concrete was leveled smothered with the hand trowel and appropriate labels (date and sample label) were written on each cube for identification.

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.

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---
