What is the effect of coarse aggregate size in compressive Aggregates for Concrete GreenSpec

When we design mix the concrete its target strength is much less than the compressive strength of the aggregates used in the formation It can also be clearly seen in the mix design procedure that greater the maximum size of coarse aggregate used less is the cement required to achieve the target strengthRecycled concrete is created by breaking removing and crushing existing concrete to a preferred size It is commonly used as a base layer for other construction materials It is commonly used as a base layer for other construction materials

It depends on the structure whether there are steel reinforcement bars provided or it is plain concrete For concrete slabs with reinforcement as in bridge decks roof slabs and columns and prestressed concrete members 16 20 mm is the MSA maximum size of aggregate Aggregate size and shape vary too The size which can range anywhere from 3/8 inch to 2 inches or more in diameter largely determines the depth of exposure

Single size aggregate is based on a nominal size specification It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25 of which is retained in the next lower sieve A graded aggregate contains more than one single size aggregateQ How does the shape and size of coarse aggregates affect the properties of concrete A Aggregate shape and surface texture influence the properties of freshly mixed concrete more than the properties of hardened concrete
