Procedures of crushing aggregates

Update date: Aug 31

Procedure of Aggregate Crushing Value Test. Put the cylinder in position on the base plate and weigh it (W). Put the sample in 3 layers, each layer being subjected to 25 strokes using the tamping rod. Care being taken in the case of weak materials not to break the particles and weigh it (W1)

    The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report

    Jan 01, 2019 The coarse aggregates obtained by different crushing mechanisms (jaw and impact crushers) show very similar characteristics in terms of binder content assessed by acid leaching (27.5 and 26.6 wt.%), water absorption (8.76 and 9.75 wt.%) and porosity (18.6 and 20.2 vol.%).Thus, it is not possible to conclude that any of these mechanisms are more efficient in removing the cement paste
