It was pointed out that due to the unprecedented development in Guyana there was a tremendous demand on the local aggregate crusher run and stone supply which saw prices in some places increasing by 100 per cent
Recycled aggregate classification is proposed in terms of water absorption input concrete strength and energy of crushing Abstract This is logical since the laboratory jaw crusher is meant for crushing stronger materials rocks and metals In this regard even high strength concrete can be regarded as a soft material for such a powerful
Further laboratory tests like angle of repose AoR and VCA drc were conducted to identify the influence of aggregate morphology on the performance of aggregates The results showed that aggregates produced from JH series of crusher had higher F&E ratio higher texture and lower sphericity as compared to aggregates from JCV series of crusher
Hence the gradation mixes of crusher dust and Crusher stone aggregate with an addition of 20 30% with respect to Crusher stone Aggregate attaining CBR value greater than 50 can be recommended as Base course and Sub base course materials and the mixes having CBR greater than 30 can be used as Sub base material Conclusions Sizes of crusher
