The 150mm ACV apparatus consists of steel cylinder with a nominal diameter of 150mm, a plunger, baseplate, tamping rod and measure. All surfaces that come into contact with the aggregate are cadmium plated against corrosion.
In road construction, the quality of aggregates is assessed by the crushing strength of aggregates.For higher quality of roads, the aggregate should possess low aggregate crushing value. Here I am going to teach you how to determine the crushing strength of aggregates.First, let us check what are the various apparatus needed for this experiment.
The tests include Specific Gravity (SG), water absorption, Los Angeles abrasion test value (LAA), Aggregate Impact Value (AIV), Aggregate Crushing Value . Generally, the studied rock masses were between three to four joint sets from which we concluded that some rock types can be excavated by loader without blasting.
