If the concrete contains course aggregate particles that would be retained on a ___ siev, wet-sieve a sufficient amount of the representative sample over a ___ sieve, as described in practice C172. A) 1", 1.5" B) 1.5", 2" C) 2", 2" D) 2", 1.5" I have it narrowed down to either A or B, leaning towards A but my book is so faded I can barely read certain sections. Anyone able to help me out?
