Abstract:In recent years, there has been significant research and product development in the field of nanotechnology – using particles of approximately 1 and 100 nm in size. From medicines, to electronics and coatings, the answers to ‘big problems’ are being provided by ‘tiny solutions.’
In the cement and concrete field, nano‐structural models of Calcium Silicate Hydrate (C‐S‐H), have allowed researchers to develop particles to improve and increase C‐S‐H formation. Additionally, micro particles have the ability to address durability issues that have plagued concrete for decades.
The practical challenge continues to be how to introduce these micro‐ and nanoscale particles into the concrete matrix. A logical option is in the form of a liquid admixture added to the concrete mixture during batching.
This paper will focus on the current and emerging micro‐ and nanoscale particulate‐based admixture technologies for concrete and their effects on the hydration process and long‐term durability of concrete. The information to be presented will show that the use of these particulate‐based liquid
admixtures offer different options for modifying and improving the fresh, hardened and durability properties of concrete.
