    The proportion of voids to volume of well graded sand is 30 to 35 per cent and that of coarse aggregate between 30 and 45 per cent. This should represent the amount of cement required to fill the interstices in the sand and the amount of sand required to fill the interstices in the coarse aggregate.Suggested Compaction Standards for Crushed Aggregate,vibrating roller.

  • Relationship of void ration to rock size/shap Soil

    Jan 05, 2009· Stone storage is commonly designed with a best-case value of 40% voids, hence my concern that the terms may have been swapped. As long as everyone is using the same parameter Your void ratio or 0.40 is equivalent to.4/1.4 voids = 29% voids, which is probably more realistic than the common 40% value.Crushed Stone Grades: A Complete Guide,Crushed stone has continuously been used for a variety of construction needs because of its versatility. Crushed stone uses can vary from base material for pavers and bricks to being used to dress up areas for walking and driving. When it comes to crushed stone grades, it’s categorized by the size of the stone after it has been crushed.

    Cu, a value employed to quantify how uniform or well-graded an aggregate is: Cu = D60/D10. 60 percent of the aggregate, by mass, has a diameter smaller than D60 and 10 percent of the aggregate, by mass, has a diameter smaller than D10.PROCEDURE FOR DETERMINING ROCK WEIGHTS, SIZES ,These weights would meet the percent passing criteria. However, this would be considered a poorly. graded material because there would be no sizes between 7.3 inches and 10.3 inches, etc. All sizes should be represented in the total sample to have a proper gradation. Variation in the size allows for better filling of voids,

    Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value.

    AGGREGATE VOIDS There are aggregate particle voids, and there are voids between aggregate particles. As solid as aggregate may be to the naked eye, most aggregate particles have voids, which are natural pores that are filled with air or water. These voids or pores influence the specific gravity and absorption of the aggregate materials.
