The aggregate is introduced at the top of the pile and is allowed to flow over the side. This action, called sloughing, causes a size segregation to occur with the finer material deposited towards the top of the pile.

Aug 11, 2020 The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30 . If it is than 30 then 10 finer aggregate is suggested to use. The aggregate whose crushing value is less than 30 can be used for cement concrete road. The aggregate whose crushing.Uses Of The Abrasion Test. For an aggregate to perform satisfactorily on the pavement, it must be difficult enough to resist the abrasive effect of traffic for a long period of time. Soft aggregates will be quickly crushed into powder, while hard aggregates are quite resistant to crushing. The test will also determine the quality of the aggregate.

The following tests were conducted on the plain aggregates coated with different amount of plastic waste. - Aggregate impact value - Aggregate crushing value - Specific gravity - Water absorption The four type of aggregates are taken as shown. Aggregates without plastic and aggregates coated with of waste plastic equal.Roughp angular aggregates offer a greater impact resis tance than do concretes made with smooth, rounded aggregateso The number of blows and the energy absorbed to first crack increased with increased crushing strength but the results exhibit considerable scatter (due. In part of course, to the effect of different aggregates).

Aggregate have openings ranging from 1.18 mm to 100 mm (0.046 in. to 4 in.). Tolerances for the dimensions of open-ings in sieves are listed in ASTM E 11 (AASHTO M 92). Size numbers (grading sizes) for coarse aggregates apply to the amounts of aggregate (by mass) in percent-ages that pass through an assortment of sieves (Fig. 5-5).A strong aggregate is concerned, can be determined only by pilot-kiln testing and by crushing-strength tests made on concrete test, cylinders.
