Mechanical properties Microstructural analysis Nanoparticles Recycled aggregate Titanium dioxide Virgin aggregate With the inclusion of sophisticated nanomaterials into traditional building materials, the area of construction and civil engineering has undergone a tremendous revolution in recent...

... were tested for workability, mechanical and durability characteristics. Microstructural analysis was performed on cement concrete blended with fly and pond ashes and compared to conventional concrete samples. Findings All concrete mixes showed better flowability with values greater than 200 mm...

... are identified as the most convenient method for improving the mild steel alloys weld quality. Originality/value A novel approach called mechanical vibrations during the process of welding is implemented for fusion zone refinement. Tensile strength Residual stresses Microstructural analysis Vibration...

.... This is because of fine grain structure at this frequency, which is observed through the microstructure analysis. Originality/value A novel technique is introduced to refine the weld-pool through electrode vibrations. To improve the hardness of the welded joints, vibrations play a major role by refining...

... some of the conventional metallic monolithic alloys. Key words: Metal Matrix composites, Stir casting, Microstructural analysis 1. Introduction In conventional casting process, liquid metal is poured into a mould and solidifies as heat is extracted from the mould walls. The morphology of the growing...
