The study deals with the temperature stress distribution on concrete and fly ash concrete slabs by non linear (Quadratic Temperature Profile) method. Concrete and fly ash concrete slabs of size 1000mm x 1000mm x 150mm were cast. Cement was replaced by 10, 20, and 30 % of fly ash. M40 grade concrete was used for the study. Temperatures were measured at top, middle and bottom of the slab by using thermocouple for 7 days at every one interval from 6 am to 8pm after 28 days curing. The study shows that actual temperature distribution across the depth of slab was highly nonlinear. The temperature stresses were calculated by Quadratic Temperature Profile Method. Temperature stress gets reduced with increase in percentage of fly ash replacement.

Temperatures were measured at top, middle and bottom of the slab by using thermocouple for 7 days at every one interval from 6 am to 8pm after 28 days curing. The study shows that actual temperature distribution across the depth of slab was highly nonlinear. The temperature stresses were calculated by Quadratic Temperature Profile Method. Temperature stress gets reduced with increase in percentage of fly ash replacement.
