Relationship of void ration to rock size/shap Soil

05-01-2009· You could specify the voids and let the contractor select the stone. Or you could specify 1.5" to 3" clean stone, as others have suggestes, but the actual voids will be subject to variation depending on the exact shape of the rock. You would have to test the actual stone to be sure. BTW, this is a common problem.

A heavy sand is generally denser, and therefore better, than a light sand, as it ordinarily indicates coarseness and good grading of particles, with correspondingly low percentage of voids. This, however, is a very unsafe guide to follow, on account of the fact that the presence of moisture may cause as much as 20 per cent variation in weight, and fine sands require more water than coarse.

Different Types & Sizes of Aggregate for Concrete

11-08-2018· Fine Aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it. Natural sand is generally used as fine aggregate, silt, stone dust and clay also come under this category.

Difference Between Fine and Coarse Aggregate Civil

Coarse aggregates are the particles that retain on 4.75 mm sieve. 3: Materials: Sand, surki, stone screenings, burnt clays, cinders, fly ash, etc are used as fine aggregate in concrete. Brick chips (broken bricks), stone chips (broken stones), gravels, pebbles, clinkers, cinders etc. are used as coarse aggregate in concrete. 4: Sources

screening grading sizing sand aggregates

In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate. Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement. Mix that occupies the least volume is the densest and will produce the best results. Get Price
