ABSTRACT In an attempt to reduced non-renewable material usage, reduce green-house substances and at the same time be relevant to our environment, this research presents the progress of investigation going on to evaluate some properties of POEBA as partial replacement of cement in the production of structural concrete. This research work is carried out to determine the properties of Palm Oil Empty Bunch Ash (POEBA) when used as partial replacement for Ordinary Portland Cement (OPC) in concret...
ABSTRACT Concrete is the most common construction material in the world today. It is used as a material in structural elements of most buildings of the world and most building failures including collapse are associated with failure of concrete either as produced or as assembled. The variations in strength of concrete is as a result of several factors that could be the varying quality of materials, the variation in the mix proportion and the varying production processes that include batching,...
ABSTRACT In an attempt to reduce non-renewable material usage, reduce green-house substances and at the same time be relevant to our environment, this research presents the progress of investigation going on to evaluate some properties of EPO-FBA as partial replacement of cement in the production of structural concrete. This research work is carried out to determine the properties of Empty Palm Oil Fruit Bunch Ash (EPO-FBA) when used as partial replacement for Ordinary Portland Cement (OPC) ...
Abstract This study investigates the effect of Date Palm Seed Ash (DPSA) as a pozzolan on the workability, compressive strength and water absorption capacity of concrete. Temperature regulated kiln was used to burn the Date Palm Seed (DPS) into DPSA in two stages: it was first burned for eight hours at an optimum temperature of 590oC and then cooled for two days. It was again burned for three hours at an optimum temperature of 630oC for eight hours and was air cooled again for three days. The...
Nowadays, consumption of rice is increasing that leads to the greater demand in the production of it. After harvesting and shelling, husk remains and comes in great volume. Thus this rice husk is one of the big problems to be considered. Some studies suggested a solution to put rice husk ash as partial substitute to cement in concrete mixing in order to minimize the large quantity of rice husks build up as time goes by. Reinforced concrete is concrete in which reinforcing bars or other typ...
This research investigates the improvement of the mechanical and durability properties of concrete using Date Palm Seed Ash (DPSA) as partial replacement of cement. The DPSA used was obtained by controlled burning of date palm seed in a kiln at a maximum temperature of 630oc for eight hours and after cooling, it was sieved through 75um sieve and its oxide composition analysis was conducted using X-ray fluorescence (XRF) procedures. DoE method of mix design was used to produce concrete ingredi...
ABSTRACT This work investigated the structural characteristics of lime cement concrete using 30 selected mix ratios. The properties studied include, compressive strength, flexural strength, splitting tensile strength, shear strength, poisson ratio, modulus of elasticity, and modulus of rigidity. A total of 360 concrete cube specimen, 360 concrete prototype beam specimen, and 360 concrete cylinder specimen were cast and cured in open water tanks. 3 specimen were cast for each mix proportio...
Abstract Nowadays, the natural material as agriculture waste in concrete has long been discussed. Coconut shell is one of the most vast and readily available agricultural solid waste in many tropical countries. The properties of coconut shell are examined and the use of coconut shell aggregate as construction materials are evaluated. This study focused on the effect of coconut shell as fine aggregate replacement on the performance of concrete in terms of the mechanical properties and physical...
ABSTRACT The research investigated some mechanical properties of aluminium waste concrete to harness its structural properties in the construction industry. Aluminium waste which was obtained from Aluminum Extrusion Industry (ALEX) Inyishi in Ikeduru Local Government Area of Imo State was investigated. The mathematical models for the optimization of the compressive and flexural strengths of a five-component concrete mix was obtained. A computer program for the optimization of the compressive...
Abstract Sustainable concrete provides a considerable solution to the increasing cost of conventional concrete production in the world. Though, it is generally described as cheap, however it’s design and cost implications for low income communities needs to be evaluated. Hence, this paper evaluates the production of sustainable concrete and its cost implication in Nigeria. Experimental design of high strength concrete made with steel fibre and bamboo fibre as reinforcement having a targete...

This paper attempts to study the mechanicalbehaviour of coconut shell aggregate (CSA) concretesubjected to elevated temperatures when coconut shell (CS)is used to replace coarse aggregate at 0, 10, 20 and 40% inconcrete. The coconut shell used was obtained by breakingthe shells into smaller sizes of less than 20mm after thefibres were removed. In order to produce control concretesamples with a minimum compressive strength of 15N/mm2at 28 days curing age, mix ratio of 1:2:4 and water-cementrat...
ABSTRACT The purpose of this project work is to assess the strength of No-fines concrete pavement. No-Fines concrete is use in low traffic volume, pathways, sidewalk and parking lots. No-fines concrete is produced by using ordinary Portland cement, coarse aggregates, and water. In this study, Two (2) batches of no-fines concrete each with two different water – cement ratio 0.36 and 0.45 and cement – coarse aggregate 1:4 and 1:6 were prepared to find the mix that generated high compressive...
