Selection of Maximum size of aggregate for concrete

2021-6-30  For most work, 20 mm aggregate is suitable. Where there is no restriction to the flow of concrete into sections, 40 mm or larger size may be permitted. In concrete elements with thin sections, closely spaced reinforcement or less cover, consideration should be given to the use of 10mm nominal maximum size. Plums above 160 mm and up to any ...
