Effect of Plasticizer on Hydration and Rheological Behavior of Cement Pastes

open access: yesCivilEng, 2022
Lignosulfonate-based admixtures (LS) obtained from sulfite pulping processes were the first dispersants added as a water-reducer to concrete. Less effective than the latest superplasticizers, the low cost and low environmental footprint of LS continue to

Effect of Suction on Volumetric Yielding Behavior under Different Initial Conditions for Fine-Grained Soils [PDF]

open access: yesEngineering and Technology Journal, 2013
The unsaturated soils are difficult to consider within the framework of classical (saturated) soil mechanics. In general, the unsaturated soil is stiffer than the saturated one (hardening), so the location and slope of normal consolidated line (NCL) or ...
