Jul 15, 2020 15 July 2020. When one of the largest crushing operations in Oman needed to raise its production by 30%, Weir Minerals knew that a Trio TP350 cone crusher was the answer. It was a demanding application, involving the crushing of hard, coarse-grained gabbro for use as construction aggregate. Gabbro has a high compressive strength of 220 to 230 MPa and an abrasion index of 0,45

Sep 19, 2020 compressive strength grades. Concrete mixes produced with general use Portland cement and various RCA contents were investigated in terms of their key mechanical and durability performances. The mechanical properties (crushing value) of the used RCA were visibly lower than the natural coarse aggregates (NCA). Thus, RCA-concrete showed lower

Jul 10, 2021 Fig. 4 revealed that the best ratio of cement concrete fly ash mix along with highest crushing strength was achieved by mixing 5% fly ash in cement concrete mix. The crushing strength increased in 5% mix when moulds were kept for 14 and 28 days which allowed curing. The crushing strength achieved by mixing 10% fly ash did not show much differences over 7, 14, 28 days
