Thermal analysis of cement pastes with superabsorbent polymers

open access: yes, 2013
Thermal analysis of cement systems is very helpful in the understanding of many different properties of cementitious compounds, both for the original reacting compounds, and also for the resulting hydration products.

Preparation of carboxymethyl cellulose superabsorbents from waste textiles Fibers and Polymers

open access: yes, 2014
Production of superabsorbent polymers from cotton and viscose waste textiles was investigated. The cellulose wastes were carboxymethylated, crosslinked by divinylsulfone, and then converted to superabsorbent material using air-drying, freeze-drying, or ...

Influence of Superabsorbent Polymers on Hydration of Cement Pastes with Very Low Water-to-Binder Ratio

open access: yes
Superabsorbent polymers have been applied e.g. for frost resistance improvement, rheology modification, controlled release of admixtures, crack healing, surface curing and removal of concrete contaminants, and recently for reducing the coefficient of ...

Fine coal dewatering using pH- and temperature-sensitive superabsorbent polymers

open access: yes, 1997
Water is a necessary medium in most coal preparation processes, but its presence in the final product has a negative impact on transporation costs, handling and specific energy value.

Internal Curing Using Superabsorbent Polymers for Alkali Activated Slag-Fly Ash Mixtures

open access: yes, 2019
Increased shrinkage is often noted as a concern for alkali activated materials. In this study, two slag-fly ash paste and mortar mixtures with slag:fly ash ratios of 30:70 and 50:50 activated using 4M sodium hydroxide are formulated.
