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...
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...
PREFACE In structural detailing, the project is initiated by the structural engineer. The architectural drawings are prepared by the architect to the required scale and specification given to him by the client. The structural engineer designs the structural frame work of the building and specification required such as slab, beam, column and foundation. For proper clearification and understanding, the structure is broken down into its component parts and detailed keeping in mind the design co...
ABSTRACT In the sense that the materials involved in this project were capital intensive more especially cement, so in carrying out the work one must intensive to be careful in the selection and collection of materials to be used in the casting of the concrete. The materials used are coarse aggregate (granite) fine aggregate (sand). The coarse aggregates used in this work were collected from ishiagu while the fine aggregate was collected in front of the carpentry’s workshop on the cam...
ABSTRACT This study is centered on the analysis of business objective and their accomplishment through effective cost control in lake concerted industry-limited Enugu. There are lots of problem that face the industry, some of which are shortage of raw materials, excessive demand, ineffective stock planning and inefficient stock management. The study therefore embarked on how the industry should form a strong stock management policy thereby forming a stock management committee that will monit...
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...
ABSTRACT The main aim of the research is to study the mechanical properties of concrete and heir effects in concrete stability and failure. He fractures mechanical properties in particular uniaxial tensile strength Ft, young’s modules Eo and fractures energy Gf as sell as the shape of the stress strain and the stress- deformation relation were investigated for high strength and normal strength concrete. In order to analyzed failure mechanism of the entire fracture cement pasture and cemen...
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...

The strength performance of UHPFRC with micro and hooked-ends steel fibers was studied in this paper using Finite Element (FE) modelling and simulation. The specimens were modelled in geometry, material, constraints, load and boundary conditions using ABAQUS package and dynamic explicit analysis was used to to investigate the crack pattern, failure mode and stress-stain behaviour of the UHPFRC specimens when subjected to uniaxial compression and tension loading. Results from the FE simulation...
