In the majority of concrete works, aggregate sizes of 20 mm or smaller are used. To ensure good coarse aggregate compaction and higher concrete density, it is recommended to mix 20 mm and 10 mm coarse aggregates in the ratio of 70:30 or 60:40. It is recommended to stack different aggregate sizes to use them efficiently.

The maximum size of the aggregate is 40mm. Dimensions of Plain Concrete Bed The plain concrete bed thickness ranges from 10cm to 15cm. The plain concrete layer should extend about 15cm from the stone masonry foundation on each side of bottom course. So, the width of plain concrete is 30cm wider than the bottom course of stone masonry footing.

increase in aggregate size results in a decrease in the compressive strength of concrete. Cook (1989) showed that, for compressive strengths in excess of 69 MPa (10,000 psi), smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used

In concrete slabs, the nominal maximum size should not exceed three-fourths of the minimum clear spacing of reinforcing bars or one-third of the section depth (ACI 302.1R). The commentary R26.4.2.1(a)(5) of ACI 318-19 states that the size limitations on aggregates are provided to facilitate placement of concrete around the reinforcement without honeycombing due to blockage by closely-spaced
