Compressive Strength Test Of Concrete Detailed Guide
OBJECTIVES 1. Determine the aggregate crushing value of coarse aggregate 2. Assess suitability of coarse aggregates for use in different types of road APPARATUS REQUIRED 1. A steel cylinder 15 cm diameter with plunger and base plate.We calculate the value ranges of the parameters C, ε, and σ by formulas 21, 22, and 23, respectively. The calculation results are shown in Table 4. (21) (22) (23) where y̅ is the average value of crushing force, σ t is the standard deviation of crushing force, and z is the number of parameters that affect fertilizer crushing force.
