Coarse Aggregate $($CA$)$: Crushed Gravel, Nominal Maximum Size $($NMS$)$

Sieve Analysis: As per OPSS.PROV Section $5\mathrm{.}2\mathrm{.}1,$ the CA grading shall conform to Class No$.5$ of Table $5-1.$ This specifies the percentage of CA passing through specified sieve sizes, ensuring optimal particle size distribution and workability.

Relative Density and Absorption: OPSS.PROV $1002,$ Section $5\mathrm{.}2\mathrm{.}3\mathrm{.}1,$ requires a minimum relative density of $60\%$ for crushed gravel CA$.$ This indicates appropriate packing and strength potential. Additionally, Section $5\mathrm{.}2\mathrm{.}3\mathrm{.}2$ sets a maximum water absorption limit of $5\%$ for crushed gravel CA to prevent excessive water consumption and potential cracking.

Amount Finer than $75$ pm by Washing: OPSS.PROV $1002,$ Section $5\mathrm{.}2\mathrm{.}4,$ specifies a maximum allowable amount of $($by weight$)$ of material passing the $75$m sieve after washing. This limits the presence of very fine particles, reducing bleeding and potential segregation within the concrete mix
