condition). Aggregate Crushing Value (ACV) is one of the important properties of coarse aggregate. ACV gives a relative measure of resistance to crushing under gradually applied compressive load. Thus ACV is inversely related to strength of coarse aggregate.

This Part of BS 812 describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to

Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.

4000 psi, 5000psi. The process of concrete mix design and determination of Aggregate Crushing Value according to ACI 211.1(ACI 211.1, 2009) and BS 812-110 standards (BS 812-110, 2009)was used in our project work respectively. For ACI mix design procedure

The materials used to develop the concrete mixes in this study were fine aggregate, coarse aggregate, rubber aggregate, cement, water and admixture. A total of 16 mixes were prepared consisting of four types of concrete grades (C15, C25, C30 and C40) with partial replacements of the coarse aggregate by 10, 25 and 50% of the rubber aggregate.

Subaru''s EZ36D was a 3.6-litre horizontally-opposed (or ''boxer'') six-cylinder petrol engine. Replacing Subaru''s EZ30R, the EZ36D engine was first introduced in the Subaru B9 Tribeca in 2007 and subsequently offered in the BM/BR Liberty, BR Outback, BN Liberty and BS Outback. Compared to the EZ30 engine, changes for the EZ36D included:
