· Parameters involved were crushed washed aggregate, natural unwashed aggregate, and four different water cement ratios. Natural aggregates are characterized as porous limestone rocks with high water absorption, low bulk specific gravity, excessively dusty degraded, and contain large quantities of very fine sand.

moisture content and also increase in workability at higher moisture contents. Methodology: Crushed stone aggregate was obtained from nearby stone crusher plants of Visakhapatnam. After brushing the aggregate it was washed and dried. A set of sieves such as

Sand moisture content Test is one of the important tests of present in sand affects the watercement ratio in the concrete mix.. Generally, moisture in form of thin layers attached to the sand particle, and because of the particle size of the sand particle is lesser it attracts more moisture from the atmosphere compared to coarse aggregate.

 · This 4 pounds of moisture or water becomes part of the mix water. Newly delivered sand, in the early part of the day, will have more free moisture. After a rain the sand may briefly have even more than 6 percent coarse aggregate contains less free moisture .

Crushed sand particle though shaped, does not have the spherical shape of natural sand. Hence the crushed sand will have greater water demand than that of natural sand resulting in slightly higher cement consumption. However, if crushed sand is properly graded with adequate fines the mix may have lower water demand when compared to poorly ...
