  • PREDICTING THE INFLUENCE OF MINERAL ADDITIONS ON REACTION AND PROPERTY DEVELOPMENT IN CEMENTITIOUS MIXTURES
    Publication number: 20150142336
    Abstract: A mechanical property of a cementitious mixture is predicted by: (1) receiving user input characterizing a mixture of a cement and a mineral addition, the user input corresponding to at least one of: (a) a size characteristic of the cement; (b) a size characteristic of the mineral addition; and (c) a replacement level of the cement by the mineral addition in the mixture; (2) based on the user input, deriving a predicted cumulated heat released by the mixture through hydration for a reaction time period; and (3) based on the predicted cumulated heat released, deriving a predicted mechanical property of the mixture at an age corresponding to the reaction time period.
