aggregate impact value. Values obtained in these tests are given in Fig.7. The tested aggregate impact value varies from 6.81% to 12.11%. Aggregate Impact Values (AIV's) below 10 are regarded as strong, and AIV's above 35 would normally be regarded as too weak for use in road surfaces. AIV values for both material tested are exhibit strong enough.

Mostly, there are investigations about the shrinkage of the concrete. In that research, only the effect of the coarse aggregate on shrinkage is investigated; the fine aggregate is taken into account with the coarse aggregate. When the aggregate grain size increases or decreases, which results will be obtained and how this situation affecting the shrinkage should be determined.
The values obtained in aggregate impact value and aggregate crushing value tests are influenced by intrinsic geological factors namely, petrology, petrography, and fabric (Ramsay et al., 1974). A high crushing value indicates a weak, potentially non-durable material (McNally, 1998).
3.4 Aggregate Attrition Value The aggregate attrition value of RA4 was found to be more as compared to NA and other three types recycled aggregate. Graph 4: Aggregate attrition value 4.

Steel ball bearings in the hardness test To produce the abrasive action using standard steel balls that, when mixed with the aggregate and rotated in a drum for a specific number of revolutions, impact the aggregate.. The wear per age due to friction with steel balls is determined and is known as the abrasion value.
The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.
12%Dolerite, granite, limestone aggregates of different sizes have been tested. No basic relations have been found between elongation index, IE, and flakiness index, IF, and the different aggregate sizes. Aggregate impact value, AIV, aggregate crushing value, ACV, and 10 per cent fines loads, however, are aggregate size dependent.
Aggregate impact value, aggregate crushing value, flakiness and elongation index of the limestone aggregates Full size table Hartley ( 1974 ), Ramsay et al. ( 1974 ), Lees and Kennedy ( 1975 ) and Kazi and Al-Mansour ( 1980 ) have addressed the many geological factors that affect the mechanical degradation of aggregates.

Importance of Impact Test on Aggregates. The impact test on aggregate is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.. The need for impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading.
the optimum replacement of coarse aggregate was found strength out. The results showed that the addition controlof plastic aggregate to the concrete mixture improved the properties of the resultant mix. concretes Plastic aggregate is a lightweight material with specific gravity 0.94. The workability of concrete increased by
