Although resincoated sand will crush in a similar fashion to sand since the resin coating encapsulates crushed particles it helps prevent fines migration On the other hand ceramic proppant crushing results in much larger size particles which are more difficult to migrate and therefore are less likely to plug the fracture throats Ghosh.
May 22 2020nbsp018332The crushing value of aggregate is very important to know the strength of the aggregate For finding the resistance of aggregate under gradually applied compressive load the crushing value test of aggregate is done For the crushing value test the following procedure is followed Procedure for finding the crushing value of aggregate.
