Concrete is a heterogeneous composite material with multiple components that have different thermal expansion properties. Internal stresses are generated if the concrete is rapidly heated or cooled, causing cracking in the micro-or macro-scale. If the coefficient of thermal expansion (CTE) of harden
Miniature, saturated, hardened cement paste specimens were pretreated for 2 days at various temperatures in the range 20-92Β°C. Specimens were then loaded for 6 days and unloaded; immediate, creep and recovery strains were monitored, as were changes in the microstructure --polysilicate and nitrogen $
