Influence of Polymers on the Nucleation of Calcium Silicate Hydrates [PDF]
Cement and Concrete Research, Volume 174, December 2023, 107329, 2021 Calcium silicate hydrates (C-S-H), the main components of hydrated cement, are known for being responsible of its cohesion. In this respect, they act as "glue" for the other solid components of mortar or concrete and thus strongly influence the mechanical properties of the outcoming material.
