ABSTRACT
Sugarcane Bagasse is the fibrous residue leftover when sugarcane is squeezed for its juice. Bagasse ash is obtained by subjecting Bagasse to calcinations using furnace. This work is aimed tat using Bagasse Ash as a replacement in the production of concrete.
The bagasse was collected from dumped in a market in Kano and thereafter sun-drie to eliminate any trace of moisture. It was then taken to the blast furnace for calcinations(controlled burning) at a temperature of 1250OC for 25minutes.The ash was then weighed and sieved with a 90μm standard sieve and the quantity retained on the sieve (black carbon) was weighed and discarded. The ash collected was investigated and its chemical compositions were obtained. Normal Consistency and Setting time for Cement and bagasse ash were determined. The concrete was batched using mix ratio 1:2:4 and the cement was replaced in varying percentages of 5%, 10%, 15%, 20% and 25% using Bagasse ash. Thereafter, the concrete was cured for 7, 14, 21, and 28days and its properties both in fresh and harden state were determined.
The result for Normal consistency of cement was achieved at 35% of water cement ratio (140ml of water added) which is equal to 34mm penetration. While Normal consistency for Bagasse ash was achieved at 33% of water Sugarcane Bagasse Ash (SCBA ) ratio (132mls of water added) which is equal to 35mm penetration. Hence, the cement and bagasse ash are satisfactory for normal consistency of 34 to 35% range of specification. The Slump of the concrete shows a slight reduction as the bagasse ash content increases. Also, the results of the compressive strength of concrete at 20% replacement has highest compressive strength of 19.94N/mm2 at 28 days.

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 Preamble Concrete is the most commonly used construction material in the world. It is basically composed of two components: paste and aggregates. The paste which acts as binder contains cement, water and occasionally admixtures; the aggregate contains sand and gravel or crushed stone (Naik and Moriconi, 2003). The aggregate are relatively inert filler materials which occupy 70% to 80% of concrete and can therefore be expected to have influence on its prope ... Continue reading---
CHAPTER TWO - [ Total Page(s): 6 ]The most common classification of Portland cement is that of ASTM. It classifies Portland cement mainly into five groups (non-air entrained) differing only on the relative amount of the compounds and the degree of fineness. • ASTM type I cement is a general purpose Portland cement used when there is no special property required by the concrete. • ASTM type II cement is Moderate Portland cement. It is also a general-purpose cement to be used when moderate sulphate resistan ... Continue reading---

The chemical composition test reveals that the bagasse ash can be classified as pozzolana.2. The workability of concrete containing bagasse ash decreases slightly as the bagasse ash content increases w ... Continue reading---
