chromite compressive strength - mon-plaisir-gourmand

Sep 13, 2011 It was found that at 28 days, the C1, C2, and C3 concretes had compressive strength of 29.5, 28.0, and 24.3 MPa, respectively, while that of R (reference) concrete was 31.1 MPa. The results showed that the higher the replacement of chromite industry waste (C), the lower the compressive strength of concrete at each curing age.

2021-11-8  To improve the high brittleness of recycled aggregate concrete containing iron ore tailings (TRAC), the feasibility of adding polypropylene fiber (PPF) to TRAC was studied by performing a compression stress–strain curve test, scanning electron microscope characterization, and a freeze–thaw cycle test. The results indicated that PPF had a beneficial impact on reducing the brittleness of TRAC.
