Using isothermal calorimetry to predict one day mortar strengths
(2016) In Cement and Concrete Research 88. p.108-113- Abstract
This study investigated whether isothermal calorimetry measurements on cement paste are sufficiently accurate and precise to partially replace compressive strengths measurements on cement mortar as a quality control method at cement production. The study was also designed to provide information on mechanisms that will affect the relationship between heat of hydration and early strength, but not to establish a general empirical relationship. Results show a fairly strong correlation at 24 h between cement paste heat of hydration and mortar compressive strength, and the strength and calorimetry measurements had similar relative repeatability. Isothermal calorimetry may therefore be a viable alternative to early age strength measurements in... (More)

Isothermal calorimetry may therefore be a viable alternative to early age strength measurements in cement production when allowed by relevant standards.
