Impact and Improvement of Crushed Tuff Sand on Sulfate

Impact and Improvement of Crushed Tuff Sand on Sulfate

Oct 10, 2018 The reason that the crushed tuff sand reduced the sulfate erosion resistance ability of concrete at low temperatures is discussed on the basis of the mineral composition of tuff rock powder, the porous structure of concrete, and the interfacial transition zone (ITZ) microstructure of concrete. The mixes of each series incorporated different percentages of very fine sand (VFS) as a replacement for fine aggregate. Results indicate that the water demand increases rapidly when the VFS replacement is more than 5 percent in natural sand concrete and more than 15 percent in crushed stone sand concrete.

Abstract- Manufactured sand is a term used for aggregate material s less than 4.75mm and which are processed for from crushed rock or gravel. due to booming of construction activities in our country, natural sand resources are 3. Santhosh Kumar.P.T et al made an attempt to study the effect of type of fine aggregate on the 28 day compressive strength of concrete. The result of the investigation indicate that the ratio of the 28 day compressive strength of concrete with crushed stone sand to that of river sand is 1.06 with a coefficient of variation of 11 %.
