WebApr 12, 2024 · Sediment porosities undergo changes with burial. In the consecutive sections the different models are explained. 1.2.1 Athy’s Model. The compaction model by Athy states that porosity falls with depth by expulsion of interstitial fluids.Pure shale samples from Oklahoma exhibit a definite relation between porosity and depth (Fig. 1.2).In the … WebThe hydration of these systems was investigated through hardening and reaction kinetics up to 365 days at 20 °C and 50 °C. The sediments used revealed two kinds of mineral assemblages and the best pozzolanic reactivity was found with quartz-rich sediments. In addition, the optimum lime content was found to be 20 wt% until 180 days. city lightz website
