This paper presents the findings of an investigation on the use of coconut shell ash (CSA) as admixture in concrete and its effect on durability performance. The CSA used was obtained by controlled burning of coconut shell in an incinerator to a temperature of 600–650ºC for 3 hours, air cooled, sieved through 75μm sieve and characterized by using X-ray Fluorescence (XRF) analytical method. The compressive and splitting tensile strengths of concrete were investigated at varying CSA additio...
This paper presents the findings of an investigation on coconut shell ash (CSA) as admixture in cement paste and concrete. The CSA used was obtained by controlled burning of coconut shell in an incinerator to a temperature of between 600–650ºC for 3 hours, air cooled, sieved through 75μm sieve and characterized based on its oxides composition determined using X-ray Fluorescence (XRF) analytical method. The effects of CSA on cement paste were investigated with addition of 0, 2, 4, 6, 8 and...
Correlation and regression in this paper were employed as analytical tools to study the degree of relationship as well asthe nature and strength of the relationship between green concrete properties and percentage replacement of cementwith civil engineering materials. Pearson product-moment method and Spearman’s correlation coefficient wereextensively used to show how correlation analysis can be practically applied in green concrete research. Least squareregression line method for both line...

COMPARATIVE ASSESSMENT OF RICE HUSK ASH, POWDERED GLASS AND CEMENT AS LATERITIC SOIL STABILIZERS. ABSTRACT This paper compares the stabilizing effects of three different materials, namely: rice husk ash, powdered glass, and cement on the properties of lateritic soil. The basic properties of the lateritic soil were first obtained through colour, moisture content determination, specific gravity, particle size distribution and Atterberg limits tests. Each of the stabilizing materials was th...
This paper presents the results of the investigation conducted to assess the latter day strengths of concrete in which the cement constituent of the mix has been partially replaced by empty palm oil fruit brunch (EPO-FBA). The structural parameters investigated were: workability, density and compressive strength. Some physical properties and chemical analysis were conducted. Slump test was used...
This paper presents the findings of a research work conducted on how to improve the mechanical 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 air cooled afterwards. The ash obtained was sieved through 75μm sieve and its oxide composition analysed using X-ray fluorescence (XRF) procedures. DoE method of mix design was used...
The effect of particle size of date palm seed ash (DPSA) on concrete properties was investigated through the use of different fineness of date palm seed ash (600um, 300um, 150um and 75um) at 2.5% replacement of cement with date palm seed ash and tested for compressive strength at 7, 21, 28 and 56 days curing duration. The consistency and setting times of cement-DPSA paste was also researched to determine the amount of water required to prepare hydraulic cement paste for testing. The date palm...
The suitability of palm kernel shell as a partial replacement of fine aggregate in concrete was researched to verify if concrete made with palm kernel shells meet some minimum standard prescribed for strength and density. Based on British standard classification of fine aggregate as aggregates passing the number 4 sieve of 4.75mm size or slightly higher sizes depending on local requirement, crushed palm kernel shells of particle diameter not greater than 5.0mm was used to replace river sand a...
A clear insight into the affinity of biochar towards water is critical for its intended application. The state of the biochar would govern its use for a particular application. For example, hydrophilic biochar is preferred when sorption or organic contaminants are concerned. It is, at present, not clearly established the factors that govern the hydrophilicity and/or hydrophobicity of a biochar. Comprehension of the factors that affect the affinity of biochar towards water would aid to create ...

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...
