MECHANICAL PROPERTIES OF ULTRA HIGH

Compressive strength of 21,500 psi was achieved with concrete made of type III cement using moist curing practice. Split tensile strength of 2,300 psi and flexural strength of 3,300 psi were gained using Type III cement and moist curing practice. Highest compressive strength of 28,150 psi is achieved using heat curing practice.Quartz Properties,The material is extremely strong in compression, with design compressive strength of better than 1.1 x 10 9 Pa (160,000 psi). Surface flaws can drastically reduce the inherent strength of any glass, so tensile properties are greatly influenced by these defects.Experimental Investigation on Concrete by,from silica sand and artificial sand as fine aggregate was studied for compressive strength, Split tensile strength and Flexural strength. So in this project, Silica sand and artificial sand had been used as replacement of fine aggregate by different percentage for making concrete of M-30 gr ade, with w/c ratio 0.42.
