HOW TO DECIDE MAXIMUM SIZE OF COARSE AGGREGATE TO BE

Mar 23 2015 0183 32 In large size aggregates surface area to be wetted per unit weight is less and the water cement ratio is less which increases the strength On the other hand in smaller size aggregates the surface area is increased which increases w/c ratio and lower strength is achieved In general for strength upto 200 kg/cm 2 aggregates upto 40 mm may be...

What nominal maximum sizes of aggregate are recommended

Because maximum aggregate size can impact concrete properties such as shrinkage and also the cost of concrete the largest aggregate size consistent with the requirements of 26421 should be permitted With the w/cm fixed the larger the nominal maximum size of aggregates the lower the cement content for a given consistency Or stated...
