TL;DR: In this article, a solution-redeposition mechanism is employed in the opal-A-to-opal-CT transformation in deep-sea sediments, showing that the transformation rate is much higher in carbonate-rich sediments than in clay-rich ones.
TL;DR: In this paper, a sample of Portland cement pastes that had been stored for 6 months in solutions of sodium or magnesium sulfate was examined by scanning electron microscopy using backscattered electron imaging and X-ray microanalysis.
TL;DR: In this article, it was shown that the change in fracture toughness with heating is the result of recrystallization, and that the poorly ordered, strongly interlocking cryptocrystalline fabric of the unheated samples becomes more equigranular and better crystallized with thermal treatment.
TL;DR: In this paper, the feasibility of low temperature CO2 sequestration into basalts including the key reactions and chemical mass transfer associated to progressive water-rock interaction was investigated in CO2-water-basaltic glass batch experiments.
