Study of Early-Age Hydration in High-Strength Concrete

Predicting the early-age strength of concrete is essential in the construction industry to meet requirements for formwork efficiency, prestress transfer, and concrete placement in cold weather. Such concrete can only be produced by using admixtures combined with pozzolanic additives. In this work, we propose substitutes for silica fume combined with specific substitution techniques. Concurrently, we propose the introduction of a combination of non-chlorinated setting and hardening accelerators. The results obtained are promising and have led to several publications in renowned scientific journals.
