Hybrid Concrete focused on the development of buildings, highways, and other structures of civil engineering. In the current study, various mix combinations have been prepared and tested with different percentages of super-plasticizer at different levels of water reduction for obtaining the optimum mix. Further, study on different properties of hybrid concrete and replacement of ordinary portla...

Groundnut shell powder contains significant amounts of the chemical silica (SiO) to be utilized as construction materials. Through use groundnut powder, this study seeks determine split tensile strength concrete (GSP). With a compressive design f'c =21.7 MPa, mixture adheres ACI 2I1.1-91. The aggregate crushed stone with maximum diameter 19.1 mm. Portland cement type I is utilized. variation 0%...

Hot-rolled AZ31 (Mg-2.57Al-0.84Zn-0.32Mn, in mass percentage) magnesium alloy is subjected to friction stir processing in air (normal friction stir processing, NFSP) and under water (submerged friction stir processing, SFSP). Thermal history of the two FSP procedures is measured, and its effect on microstructures and mechanical properties of the experimental materials is investigated. Compared ...

The influence of temperature on the strength properties of structural materials has not been studied in detail yet. In particular, there are the alloys whose dynamic elastic strength demonstrates anomalous growth with the increase of temperature. The spall strength usually shows little change with temperature, i.e. it decreases insignificantly up to 85% of the melting point, which is followed b...

In the present study, the mechanical properties of self-compacting concrete were investigated after the addition of different amounts of ZnO nanoparticles. The zinc oxide nanoparticles, with an average particle size of about 30 nm, were synthesized and their properties studied with the help of a scanning electron microscope (SEM) and X-ray diffraction. The prepared nanoparticles were partially ...

The present investigation deals with effect of bentonite clay on concrete. The concrete was produced by partial replacement of OPC with mineral admixture bentonite clay in percentages of 0%, 5%, 10%, 15% and 20%. The M20 grade of concrete was designed. The compressive strength, split tensile strength and flexural strength were found for the specimens. The present investigation is to study the e...

The results reported in this paper are the part of an extensive laboratory investigation undertaken to study the effects of fibre parameters on the permeability and strength characteristics of steel fibre reinforced concrete (SFRC). The effect of varying fibre content and curing age on the water permeability, compressive and split tensile strengths of SFRC was investigated using straight steel ...

Concrete is one of the most widely used construction material in today’s world. Cement is one of the essential constituents of the concrete. Environmental issues are also playing a vital role in today’s world, the production of cement one of the major constituent of concrete leads to release the of a significant amount of carbon dioxide a greenhouse gas contributing 7% of greenhouse gas emissio...
