abstract = "The physical properties of cement are strongly
influenced by the development of microstructure and
cement hydration. Therefore, the investigation of
microstructure for cement paste enables us to
understand the hydration process and to predict the
physical properties. However, the unreliability of
phase classification and segmentation in image affect
the description of microstructure, as well as the
prediction of properties and the simulation of
hydration. This paper studies the dynamic relationship
between microstructure and physical properties from the
image itself. The relationship between compressive
strength and microstructure image features is built as
the form of image feature kinetics using gene
expression programming from observed microtomography
images. A similarity weight tournament selection is
also proposed to increase the diversity of population
and improve the performance of gene expression
programming. Experimental results manifest that the
evolved image feature kinetics not only perform well in
fitting training data but also exhibit superior
generalisation ability.",
