Analysis of Temperature Distribution across the Thickness of Slab using Thermocouples

Concrete is most popularly used construction material all over the world. Concrete is an artificial material can be obtained by uniform mixing of cement, coarse aggregate, N-sand or M-sand and sufficient and controlled amount of water, with or without super plasticizers. Here 3 slabs cast with different material properties like slab(S1) cast with N-sand, Slab (S2) cast with M-sand and Slab (S3) cast with partially M-sand and partially N-sand. Therefore, an attempt has been made in this study to evaluate the stresses due to the actual temperature distribution across the thickness of the slab and load (as per IS:875 part-II) using empirical and analytical method viz., Finite element analysis technique. The finding confirmed the importance and the need to account the nonlinear temperature differential in the design of concrete slabs. Also, 3DFE technique using ANSYS proved to be a versatile technique in analyzing concrete slab for thermal and load stresses.
