Project Abstract

Abstract
The strength of concrete is a critical factor in determining its performance and durability for various construction applications. This research project aims to conduct a comparative analysis of the strength of concrete made from different types of aggregates. Aggregates play a significant role in the properties of concrete, influencing its strength, workability, and durability. The study will involve the use of various types of aggregates such as crushed stone, gravel, sand, and recycled materials to produce concrete specimens. These specimens will be subjected to compressive strength tests according to standard procedures to evaluate the strength characteristics of the concrete mixes. The research will focus on comparing the compressive strength of concrete samples made with different types of aggregates under controlled conditions. The results obtained from the testing will be analyzed statistically to determine the influence of aggregate type on concrete strength. Additionally, factors such as aggregate size, shape, and gradation will be considered in the analysis to provide a comprehensive understanding of their impact on concrete strength. Furthermore, the study will investigate the effect of aggregate properties on the workability of concrete mixes. Workability is essential for proper placement and compaction of concrete during construction, and the type of aggregate used can significantly affect this property. By examining the workability of concrete mixes with different aggregates, the research aims to provide insights into how aggregate characteristics can influence the ease of handling and placing concrete on-site. In addition to compressive strength and workability, the research will also explore the durability aspects of concrete made from various aggregates. Durability is crucial for the long-term performance of concrete structures, especially in harsh environmental conditions. The study will assess parameters such as permeability, resistance to freeze-thaw cycles, and chemical resistance to evaluate the durability of concrete mixes with different aggregates. Overall, this research project will contribute to a better understanding of how the choice of aggregate can impact the strength, workability, and durability of concrete. The findings will be valuable for engineers, contractors, and researchers involved in concrete construction, providing insights that can help optimize concrete mix designs based on the specific requirements of a project.

Project Overview

1.1 INTRODUCTION

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

Due to the strength/high cost of various aggregate in the market the comparative analysis of strength of concrete indifferent aggregate have revealed that one can definitely substituted in various aggregate by using the mixture design of ration in different aggregate in building to reduce the mixture ratio of aggregate or used any of the aggregates.

Where there is no granite stone washed gravel most black gravel is there no black gravel must in such area there will be surface gravel in the project is going to be sited.

A great effort have been made throughout this work although it is limited in scope to assess their suitability as stand and concrete aggregate

1.2 PROJECT OBJECTIVE

This case study the comparative analysis of the strength of concrete made from various aggregates.
The project implement the following analysis.

1. To determine the analysis in the existing aggregates and evaluate its suitability for use as a good building of aggregates by means of various laboratory tests.

2. To determine the strength of concrete cube in difference aggregates in soil laboratory with a view to have on alternative in the building construction.

3. To effect the reduction of rising in the building construction by using deference aggregates.

1.3 PARTICLE SIZE DISTRIBUTION

It has been stated that maximum size and grading of aggregates are very important find aggregate result in uneconomical mixes where as very coarse –grained soils result in harsh unworkable mixes.

The mean size or grading of many aggregate can be obtained by passing the materials in a set of sieves consisting usually of certain standard sizes. The sieves number is been expressed as the member per inches.

The sieve analysis should also conformed to the B. S. 410 of 1969 for sieves for purpose of testing the procedure involved in making sieve analysis should also conform to the B.S. standard method that is involved in carrying out the sieve analysis of time and coarse aggregate.

The aggregate were carefully washed to eliminate dust particles and some other of organics mater present in it so the aggregate should be dust and dust free of any kind. After the wash of aggregate were kept to dry in a place for 24 hours with kept help of electric oven.

The particle were weight and e recorded the % retained passing sieve at each times the graph below shows the result got from each case.
