The aim of this study is to evaluate the moisture effect on the strength of concrete specimens that has completely cured. This study is also aimed to develop relations that can be used to determine the properties of concrete with different moisture contents that are normally experienced in outside conditions. Numerous compressions and split tensile tests are performed. In order to better unders...

This study presents an experimental investigation on self-compacting concrete (SCC) with fine aggregate (sand) replacement of a Quarry Dust (QD) (0%, 25%, 50%, 75%, 100%) and addition of mineral admixtures like Fly Ash (FA) and Silica Fume (SF) & chemical admixtures like super plasticizers (SP). After each mix preparation, 45 cubes specimens and 45 cylinders specimens are cast and cured. The sp...

In spite of broad improvements in construction technology, cement is still stayed as binding material for construction purposes. Cement industries are the main sources for the contribution of carbon dioxide (co2) into the atmosphere. So, there is a need to use new materials as binders (green binders) in substitute for cement, which leads to reducing the production of cement. In this study, fly ...

This paper presents the effect of Sodium Chloride (NaCl) on Conventional Concrete (Silica Fume Based M30 Grade Concrete). The Silica Fume Based M30 Grade Concrete was prepared by adding NaCl concentrations of 0.5,2,4,6,8,10 and 12 g/l i n deionised water. In addition to this, control specimen was prepared with deionised water (without NaCl) for the purpose of co mpari son . The tensile strength...

OSTEOTRANS MX® (Takiron Co., Ltd., Osaka, Japan) is a bioactive resorbable maxillofacial osteosynthetic material composed of an unsintered hydroxyapatite/poly-l-lactide composite, and its effective osteoconductive capacity has been previously documented. However, the mechanical strength of this plate system is unclear. Thus, the aim of this in vitro study was to assess its tensile and shear str...

In this study, Wood Ash (WA) prepared from the uncontrolled burning of the saw dust is evaluated for its suitability as partial cement replacement in conventional concrete. The saw dust has been acquired from a wood polishing unit. The physical, chemical and mineralogical characteristics of WA is presented and analyzed. The strength parameters (compressive strength, split tensile strength and f...

Abstract The present study investigates the relation of compressive strength to indirect split-tensile strength, modulus rapture artificial sand concrete. For this purpose, concrete mixtures were prepared with M30 grade replacement fine aggregate partially thoroughly. Multiple regression models developed for split tensile-compressive and rapture-compressive results. also compared different code...

The present Experimental investigation is to study the Mechanical Properties of the Fly ash concrete reinforced with steel fibers. The concrete composite comprises of steel fibers in different percentages and partial replacement of cement in different proportions. Steel fibers varied from 0%, 0.5%, 1% and 1.5% by weight of cement and replacement of fly ash varied from 0%, 10%, 20%, 30% and 40% ...

This paper in essence presents comparative experimental data on the mechanical performance of steel and synthetic fibre-reinforced concrete under compression, tensile split and flexure. URW1050 steel fibre and HPP45 synthetic fibre, both with the same concrete design mix, have been used to make cube specimens for a compression test, cylinders for a tensile split test and beam specimens for a fl...
