Influence of Calcium Sulfoaluminate (CSA) Cement Content on Expansion and Hydration Behavior of Various Ordinary Portland Cement-CSA Blends
Piyush Chaunsali,Paramita Mondal +1 more
TL;DR: In this paper, the authors examined the expansion and hydration characteristics of various ordinary portland cement (OPC)-CSA blends and found that the increase in CSA cement content increased the extent of expansion.
Journal ArticleDOI
Physico-chemical interaction between mineral admixtures and OPC–calcium sulfoaluminate (CSA) cements and its influence on early-age expansion
Piyush Chaunsali,Paramita Mondal +1 more
TL;DR: In this paper, the authors examined the physico-chemical factors influencing the expansion characteristics of OPC-CSA blend in the presence of mineral admixtures, and found that the expansion behavior of the CSA mixture was influenced by the changes in the stiffness, whereas the expansion of the Class ‘C’FA-based mixture was governed by faster hydration of ye'elimite.
Journal ArticleDOI
Evolution of strength, microstructure and mineralogical composition of a CKD-GGBFS binder
TL;DR: In this article, a nontraditional binding material containing cement kiln dust (CKD) and ground granulated blast furnace slag (GGBFS) is discussed and significant compressive strength was obtained for a CKD-GGBF blend with 70% CKD and 30% GGBFS at a water-to-binder ratio of 0.40 after 2 days of curing at elevated temperature.
Journal ArticleDOI
Influence of the composition of cement kiln dust on its interaction with fly ash and slag
TL;DR: In this paper, the performance of two different CKDs as components in a novel binder is evaluated, and Ettringite and calcium aluminosilicate hydrate (C-A-S-H) are identified as the main hydration products in the hardened binder system.
Journal ArticleDOI
Mineralogical and microstructural characterization of biomass ash binder
Piyush Chaunsali,Hugo Uvegi,Rachel Osmundsen,Michael Edward Laracy,Thomas Poinot,John Ochsendorf,Elsa Olivetti +6 more
TL;DR: In this paper, a cementitious binder was formulated from biomass ash, clay, and hydrated lime using 2M NaOH solution at a liquid-to-solid mass ratio of 0.40.
