Classification & Test on Aggregate

What are Aggregate in Construction Industry ? In the construction industry, aggregate are used as filler material in the production of concrete and mortar. Aggregate occupy around 70% to 80% of the volume of the concrete, reduce shrinkage effects and minimize costs. The coarse aggregate form the main matrix of concrete and the fine aggregates form the filler …

Determination the Crushing Value of Aggregate test

Record the total weight of fines passing through the 2.36mm sieve and calculate the crushing value using the formula: Crushing Value = (Weight of Fines / Weight of Sample) × 100; Calculation. Crushing Value = (Weight of Fines / Weight of Sample) × 100. Note: Weight of Fines is the sum of the weights of aggregates passing through the 2.36mm sieve.
