High-performance heavy density concrete made with magnetite coarse aggregate with 10% SF reaches the highest compressive strength exceeding over the M60 requirement by 14% after 28 days. Whereas, the compressive strength of concrete containing barite aggregate was very close to M60 and increases up to 90 days.
Development of High- Performance Heavy Density Concrete ...
The hardened concrete mixes were tested for compressive strength at 7, 28 and 90 days. In some concrete mixes, compressive strength was also tested up to 90 days upon replacing sand with the fine portions of magnetite, barite and goethite. The attenuation measurements were performed by using gamma spectrometer of NaI (Tl) scintillation detector.
