ABSTRACT The national housing policy of Ghana which was approved by cabinet in 2010, advocates the use of local building materials for the construction of buildings. It is against this background, that in recent years many studies have been conducted to find cheap but useful local building materials to replace the conventional ones which are to some extent expensive. Cement is one of the most important elements in building construction works which is relatively expensive. This research...
ABSTRACT There has been a growing concern in the development of alternative building materials to ensure housing for low-income earners who cannot afford owning houses due to high cost of modern materials. Plantain (Musa paradisiaca) peels are the major byproduct of plantain fruits, constituting about 40% of the fruits but are presently underutilized. This work covers the investigation into the effect of Ripe Plantain peel ash (RPPA) and Unripe Plantain peel ash (UPPA) as admixtures to concr...
ABSTRACT Concrete is a mixture of fine aggregate (sand), coarse aggregate (rock), cement, and water. The increasing demand of concrete for construction and development of infrastructure has drawn the attention of many researchers in searching for less expensive alternatives to the traditional materials employed in the construction industries in an attempt to reduce the high cost of construction. This paper features an experimental study on the replacement of sand with quarry dust and its inf...
ABSTRACT The work has gone a long way in determining strength of concrete made of various aggregates such as granites stone, black gravel, washed gravel and surface gravel. Some factors such as porosity of the aggregate temperature causing loss of water plate form for mixing of concrete mix affect the workability and eventually the strength of concrete. This project work consist of using hydraulic machine to carryout the compressive test of the strength of concrete made of the earlier ment...
ABSTRACT This study is on the determination of the Compressive Strength of Palm Kernel Shell Concrete. The effect of percentage replacements (0, 25, 50, 75 and 100%) of crushed granite with palm kernel shell on density and compressive strength of concrete is presented. Concrete cube specimens of mix 1:2:4 were prepared with water-cement ratio of 0.6. The cubes (150mm×150mm×150mm) were cured using water-submerged curing until testing ages of 7, 14, 21 and 28 days when their densities and co...
ABSTRACT One of the ways to increase the strength properties of concrete is adding fibre material into the concrete. While to reduce a noise in construction project, a self compacting concrete was a good choice in the project. This thesis presents a study into the strength properties of self compacting beam concrete using plantain bunch fibre. Mix proportion of 1:1.82:1.27with different fractions of fibre namely: 0.00%, 0.25%, 0.50% and 0.75% by weight of cement with water cement ratio ...

INTRODUCTION 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 c...
ABSTRACT The Reuse of waste glass in concrete production is among the attractive option of achieving waste reduction and preserving the natural resources from further depletion thereby protecting the environment and achieving sustainability. This present study examined the variation in the strength prope1ties of concrete using waste glass aggregate (WGA) as partial replacement for different coarse aggregates grading. 20mm and =(25mm coarse aggregates were partially replaced with WGA of respe...
This project work aims at formulating Scheffe’s mathematical model which prescribes concrete mix ratios for a desired compressive strength of periwinkle shell aggregate concrete and obtaining the combination of water, cement, river sand and periwinkle shell which will produce the optimum strength.The model was formulated from first principle producing an equation with several unknown coefficients. These coefficients were determined by carrying out compressive strength test on thirty c...
ABSTRACT The quality of building materials has been documented to be one of the causes of building collapse all over the world. An experimental study was conducted to determine the effect of fines (clay/silt) content in sand and water-to-cement ratio on the workability, compressive strength, tensile strength and flexural strength of concrete. A total of 270 specimens were cast and tested with varying fines content in sand of 2%, 4%, 6%, 8%, 10% and 12%; and variable water-to-cement rat...

ABSTRACT The production of concrete as a civil engineering material is highly dependent on the availability of its constituent materials. However, most of these materials are no more readily available. In order to solve this problem, many researches has been carried out on the use of agricultural waste as construction material, one of this material is Empty Palm Oil Fruit Bunch Ash (EPO - FBA). (EPO - FBA) is an agricultural waste material which is gotten after burning empty palm oil fru...
ABSTRACT Concrete is used widely in all types of construction. In particular, it is the first choice material for the construction of various industries, due to its affordability, durability, heat resistance, strength, etc. Based on this, understanding the response of concrete structural components for all types of loading is crucial to the development of an overall safe and efficient structure. Various methods have been used to study the response of concrete structural components to various...
ABSTRACT This study investigated the structural characteristics of chikoko mud-cement concrete. The structural characteristics of chikoko mud-cement concrete investigated were compressive strength, flexural strength, shear strength and split tensile strength while the elastic properties investigated were static modulus of elasticity, poisson’s ratio and shear modulus. The water absorption of chikoko mud-cement concrete as a reflection of concrete durability was also investigated. Ninety (9...
