Aggregates with lower crushing value show a lower crushed fraction under load and would give a longer service life to the road and hence a more economical performance If we used a weaker would get crushed under traffic loads would produce smaller pieces not coated with a binder and these would be easily displaced or loosened out resulting in loss of the surface/layer

Procedure of Aggregate Crushing Value Take a sample of aggregates by sieving through and retained on 10mm The aggregate shall be tested in dry surface conditions If dried by heating the period of drying shall not exceed 4 hours and temp shall be 100 110 deg C
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions
The formula then is Area = Diameter / 2 2 x Diameter in Feet Total Square Feet Oval Areas / Square Footage Oval areas need measurements similar to a rectangle Simply take the length from one end to the other and the width at the widest point The formula you
Suppose proportion of concrete is taken as 1 2 4 one part cement two part sand four part aggregates Volume of concrete work is taken as 500 cft Now in order to determine the quantity of cement in cft put the cursor on the specific cell of concrete volume and apply the formula = D2 A2 / A2 B2 C2
Aggregates • Fine Consists of natural sand manufactured sand or crushed stone <3/8 Fine aggregate will pass the # 4 sieve • Coarse Natural or crushed stone 3/8 to 1 ½ or more Coarse aggregate is larger than a #4 sieve 4 Mineralogy • Igneous Latin Fire Formed from volcanic processes and
not the additional crushed/fractured aggregates created by laboratory processes With this in mind it is important that the tester handle aggregates for this test carefully C TERMINOLOGY Crushed Particle Any particle having one or more fractured faces A crushed particle is an angular rough or broken surface of an aggregate particle created

Aggregate Blending Absorption & Specific Gravity 15 Fine Aggregate Specific Gravity • ASTM C128 Dry aggregate Soak in water for 24 hours Spread out and dry to SSD Add 500 g of SSD aggregate to pycnometer of known volume • Pre filled with some water Add more water and agitate until air bubbles have been removed
Crushed aggregates contain organic matter that can serve as fuel It can also be mixed with fuel such as finely ground coal or coke The premoistened raw materials are burnt This leads to production or release of gases causing expansion This forms clinker which is then cooled crushed and screened to the required gradation However there is no control of the shape and therefore this
