Aug 11 2018 · Typically the most common size of aggregate used in construction is 20mm A larger size 40mm is more common in mass concrete Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids When the aggregate is sieved through 475mm sieve the aggregate retained is called coarse aggregate... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
Cement grinding plant is the final stage in the production of cement, which is separated from the finished cement production units. It mixes cement clinker with other certain amount of mixed materials for grinding, and then produces the finished cement.

The larger sizes will require less mixing water and hence for a given cement factor will produce concrete of lower waterratio than the smaller sizes 3 The advantage of small aggregate in the waterratio strength relationship may or may not be sufficient toMore Details
This study investigates the effect of aggregate size on the compressive strength of concrete Two nominal mixes that is 124 and 136 were used in the studyMore Details
Also the results show that the compressive strength increases with increasing aggregate size up to 125 mm while the concrete produced using 20 mm had greater compressive strength than those produced using 25 mm aggregate This established the importance of ensuring that the right aggregate size is used in the production of concreteMore Details
The results demonstrate a significant influence of the aggregate size on the fracture behaviour of concrete There is a direct relationship between the size effect parameters obtained by Bazants law and maximum aggregate size The results obtained from the specimen having the same size but made of concretes with different aggregate sizesMore Details
Mar 23 2015 · In general for strength upto 200 kgcm 2 aggregates upto 40 mm may be used and for strength above 300 kgcm 2 aggregate upto 20 mm may be used Conditions That Decide Maximum Size of Coarse Aggregate to be Used in Concrete The following conditions decide the maximum size of coarse aggregate to be used in concreteMore Details
The concrete mixtures incorporate either basalt or crushed limestone aggregate sizes of 12 mm h in or 19 mm Y in and coarse aggregate contents with aggregate volume factors ACI 211191 of075 and 067 Watertocementitious material ratios range from 024 to 050More Details
Quality Counts Make sure that your concrete producer purchases goodquality aggregate as verified by regular aggregate test results in compliance with ASTM C 33 Standard Specifications for Concrete Aggregates A history of good performance of a local aggregate also provides an indication of how well the material performs in serviceMore Details
Perception Well if you relate the strength of concrete with the size of aggregates only then it is not justifiable because strength of cement concrete also depends upon watercement ratio The concrete which is having more watercement ratio wiMore Details
