1 天前 The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

2020.12.1 The formation of any microcracks in concrete reduces its elastic properties. Any cracking of aggregate grains, even in small quantities, e.g. weak grains, will also have a significant direct impact on elastic strains. This aggregate feature is considered by testing its crushing strength, and the measure is the aggregate crushing value (ACV) [15 ...
