Tektiti so vrsta naravnega silikatnega stekla in impaktitov. Nastanejo ob padcu velikega meteorita na površje Zemlje in s hitrim taljenjem kamnin in sedimentov. Talina je izvržena v ozračje, kjer se ohladi in morfološko preoblikuje ter nato v obliki tektitov pade na različna mesta na Zemlji, kjer us ...

The influence of different curing temperatures on the hydration of belite-calcium sulfoaluminate cement was investigated at 20, 40 and 60 °C. The hydration kinetics and the hydrated phase assemblages were studied by isothermal calorimetry, X-ray powder diffraction, differential thermal analysis and ...

RILEM TC 267 TRM– “Tests for Reactivity of Supplementary Cementitious Materials” recommends the Rapid Reliable Relevant (R3) test as a method for determining the chemical reactivity of supplementary cementitious materials (SCMs) in Portland cement blends. In this paper, the R3 test was applied to 52 ...

The influence of different amounts of gypsum on the hydration of a belite-rich and a yeʼelimite-rich belite-calcium sulfoaluminate clinker (BCSA) was investigated. The hydration kinetics, phase assemblages and compressive strength devel- opment of cements prepared using yeʼelimite/ calcium sulfate m ...

In this paper, the effects of the sintering temperature on the pore evolution of the belite-sulfoaluminate cement clinker were evaluated. Belite-sulfoaluminate cement clinker with a targeted composition of 65 w/% b-belite, 20 w/% calcium sulfoaluminate and 10 w/% ferrite was sintered at three differ ...
