The Department of Civil Engineering invites you for a webinar titled “Dissolution-Precipitation Theory of Chemo-Mechanics of Concrete” by Prof. Gurmail BenipalProfessor, Department of Civil Engineering, Shiv Nadar University, Delhi-NCR,  on Thursday, 7 April 2022 from 12:45 PM to 2:00 PM. The session will be moderated by Dr. Ghanshyam Pal, Associate Professor & Head, Department of Civil Engineering, Shiv Nadar University, Delhi-NCR.

Abstract of the Talk
Concrete structures are designed for satisfying the requirements of safety, serviceability, durability, and economy. Under service loads, concrete structures are known to exhibit time-dependent creep deflections and stress relaxation. Viscoelastic nature of concrete is believed to be the cause of such time-dependent behaviour. Durability of concrete in diverse aggressive chemical environments is investigated using stress-free concrete specimens. However, real concrete structures are subjected to simultaneous action of loads and ambient chemical environment. Thus, there is a need to understand the chemo-mechanics of concrete and formulate appropriate recommendations for design of concrete structures. 

Design Codes for concrete structures are based on available theories of materials and structures, empirical equations, and engineering judgment. Complex problems of engineering importance are solved using these theories and computational methods. Textbooks as well as research papers dealing with theories are written in the formal style. These third-person accounts do not reveal creative process of the theorist. In this Lecture, I will present first-person account of construction of my Dissolution Precipitation Mechanism and Theory. This unified theory of creep and durability of concrete predicts that reacting stressed elastic solids exhibit aging basic creep. Potential extensions and applications of the Theory will be outlined.
