TL;DR: In this article, chemical and microstructural aspects of delayed ettringite formation are reviewed, and the authors show that the rate and ultimate extent of expansion are influenced by factors of three types: chemistry, paste microstructure, which determines the stresses produced by its formation.
611 citations
TL;DR: In this article, a scheme of phase balances was proposed to calculate the mineralogical balances of a hydrated cement paste with greater accuracy than hitherto practicable, and experimentally-determined phase relationships were depicted at 25 deg. C.

TL;DR: In this article, the hydration of two CSA cements has been investigated experimentally and by thermodynamic modelling between 1h and 28 days at w/c ratios of 0.72 and 0.80, respectively.
