CHAPTER ONE

INTRODUCTION

1.1 BACKGROUND OF THE STUDY

This work was obligated to present in one. The fundamental and practical information in the filed of the comparative analysis of the strength of concrete made from various aggregate which may be useful to people involve in civil and structural engineering and particularly, those that found pleasure in the design and related structure.

Due to high cost of sand in the market the comparative analysis of strength of concrete made from various aggregate play an important role in cost of transportation, thus the cost of material.

Enugu state case a case study has quite an abundance of washed gravel, which are usually picked out from stream, black and surface gravel present in every part of the state though, in many construction sites, mostly within Enugu metropolis crushed/granites stones got from Abalikik and Nkalagu are mostly used, in the rural areas, washed gravel are mostly used because of its availability and cheapness compared to crouched stones.

The aim of this project therefore, is to compare the compressive strength produced b those washed, black, surface and granite stone got from different areas and to see if there is any way, these coarse aggregate can be interchanged during construction especially when her is shortage of any one of the materials.
