1. EFFECTS OF AGGREGATE SIZES ON THE CONCRETE STRENGTH
It is well recognized that coarse aggregate plays an important role in concrete. Coarse aggregate typically occupies over one-third of the volume of concrete, and research indicates that changes in coarse aggregate can change the strength and fracture properties of concrete. To predict the behavi...
2. EVALUATION ON THE IMPACT OF AGGREGATE SIZES ON CONCRETE STRENGTH
INTRODUCTION
It is common knowledge that coarse aggregate is crucial to the success of concrete. According to studies, changes in coarse aggregate can alter the strength and fracture qualities of concrete. Coarse aggregate generally makes up over one-third of the volume...
3. EFFECT OF MIX RATIO AND CURING WATER ON THE COMPRESSIVE STRENGTH OF OIL PALM SHELL (OPS) AGGREGATE CONCRETE
ABSTRACT
In this study, the compressive strengths and Modulus of elasticity of lightweight Concrete with oil palm shells as partial replacement of coarse aggregate was presented. The different types of mixing water were used, namely, cl...
4. EFFECT OF CRUSHED COCONUT SHELL AND POLYETHYLENE TEREPHTHALATE AS PARTIAL REPLACEMENT OF COARSE AGGREGATE IN CONCRETE
ABSTRACT
This study investigates the suitability of crushed coconut shell (CCS) and polyethylene terephthalate (PET) as partial replacement of coarse aggregate in concrete. The PET was crushed mechanically to sizes between 0-10mm while the CCS was crushed manually to sizes between 12.7-...
5. THE EVALUATION OF CERAMIC WASTE AS PARTIAL REPLACEMENT OF COARSE AGGREGATE IN HOT MIX ASPHALT
ABSTRACT The study investigates the suitability of ceramic waste aggregate (CWA) as partial replacement for coarse aggregate in asphalt concrete. In order to achieve the aim of the study, consistency tests such as sieve analysis, aggregate crushing and impact value, water absorption, particle sha...
6. AN INVESTIGATION INTO QUALITY OF AGGREGATE IN ROAD CONSTRUCTION
ABSTRACT
The current extensive use of low quality aggregate in Nigerian road for engineering applications is of concern because they appear to be a level of ignorance surrounding their existing properties and implications. This project was conceived for the purpose of c...
7. APPLICATION OF SCHEFFE’S MODEL IN COMPRESSIVE STRENGTH OPTIMISATION OF CONCRETE USING RICE HUSK ASH AS PARTIAL REPLACEMENT OF CEMENT
ABSTRACT
This study investigates the economic application of scheffe’s model in compressive strength optimisation of rice husk ash-cement concrete. Physical properties of the aggregates such as specific gravity, bulk density and sieve analysis were determined. Specific gravities o...
8. EFFECT OF SALT WATER ON CONCRETE USING BIDA NATURAL STONES AS COARSE AGGREGATE
ABSTRACT
Concrete is a combination of cement, fine and coarse aggregates and water, which are mixed in a particular proportion to arrive at a particular strength. The cement and water react together chemically to form a paste together with the aggregate particles. The mixture sets into...
