In southeast China, slope with completely decomposed granite (CDG) soil is susceptible to landslide under heavy rainfall, due the fissure-rich and slaking characteristics of this kind soil. context, study attempted hydraulically improve CDG in a low-carbon manner by using composite xanthan gum guar (i.e., two different microbial biopolymers), as an alternative cement. Hydraulic conductivity tre...

This research is based on the characterization of ancient mortars from Anfiteatro Flavio (Pozzuoli) dating back to 1st and 2nd century CE through a multi-analytical approach involving macroscopic, mineralogical, petrographic, chemical investigations. The goal that has been set deepen knowledge about mortar mix design, provenance used raw materials, secondary minerogenetic processes have occurre...

stabilizer such as cane sugar to liquid lime-sulfur and evaporating to dryncss. Self-boiled lime-sulfur is made by utilizing the heat of hydration or slaking of quicklime, CaO, to carry on the reactions with sulfur. Ammonium polysulfide and sodium polysulfide are made by passing hydrogen Sulfide gas, H.^S, into ammonium or sodium hydroxide containing excess sulfur. It is supposed that the chemi...

Abstract Co‐seismic uplift of Kaikōura Peninsula in 2016 has substantially reduced the number wetting and drying cycles that occur on shore platforms newly uplifted incipient marine terraces. A simple empirical model incorporating field laboratory measurements was used to determine frequency cycles. The mudstone supratidal terraces are vulnerable material disintegration slaking through sustaine...
