Week 1

Chemistry of Concrete

Semester:

               This week’s speaker was Dr. Leslie J Struble a Professor of Civil & Environmental Engineering  at the University of Illinois at Urbana-Champaign. She spoke on some of the chemistry of concrete focusing in on the composition of concrete. She spoke of some materials that can be substituted into the concrete. One of the things that I learned about from this seminar was that concrete has layers that can slide past each other. In addition to this I learned that the hydration reactions that take place in concrete can go on for a very long time.

Chemistry of Concrete

Semester:

Thursday the 30th of January we had a seminar on the chemistry of concrete. This presentation was by Dr. Leslie J Struble who has a B.A. in chemistry and a Ph.D. in civil engineering from Purdue University. She is currently works at the University of Illinois in the department of Civil and Environmental Engineering. She is also the Director of the Center for Cement Composite Materials at UIUC.

The Chemistry of Concrete

Semester:

This week’s seminar was about the subject of the concrete chemical make up. The seminar was presented to us by Professor Leslie J Struble. Dr. Struble is a professor of civil and environmental engineering at the University of Illinois. She holds several degrees in both chemistry and civil engineering. Dr. Struble kept a very calm composure as she presented. She relayed her information clearly and the seminar was very comprehensible despite her being late to the talk due to weather.

MAS NMR Spectroscopy of Calcium/Aluminum Silicate Hydrate Nanostructure

Semester:

This week’s seminar presentation was given by Dr. Leslie J. Struble from the University Illinois on the topic of substitution of alumina in calcium silicate hydrate for use in concrete materials. Dr. Struble investigated the effects that the composition of calcium silicate hydrate and alumina substituted silicate hydrate has on its nanostructure. The nanostructure of these materials highly depends on the length of the chains the silicate hydrates form and their cross-linking with each other. With that being said, the elasticity of the nanostructure also comes into play. Dr.
