Effects of metakaolin and silica fume on properties of concrete
, 2002 Metakaolin is a relatively new mineral admixture for concrete. It is comparable to silica fume in pozzolanic reactivity, but is lower in price. The effects of metakaolin and silica fume on various properties of concrete were investigated and compared in ...

Split‐disk testing of precast ultra‐high performance fiber‐reinforced concrete tubes
Structural Concrete, EarlyView.Abstract Ultra‐high performance fiber‐reinforced concrete (UHPFRC) has great potential for structural applications involving precast cylindrical shapes, including pipes, silos and stay‐in‐place forms for concrete columns. This study examines the performance of UHPFRC rings under internal pressure simulated using the split‐disk loading method, along ...

Journal of Vinyl and Additive Technology, EarlyView.The synergistic interaction between red phosphorus (RP) and zinc borate (ZnB) enhances the thermal stability and flame retardancy of TPU by forming a dense, stable protective char layer. Non‐isothermal kinetic analysis confirms a complex degradation mechanism governed by conversion‐dependent activation energy.
