Expansive admixtures

Expansive admixtures are additives used in concrete to induce controlled expansion. They react with alkalis in cement to generate expansive compounds, resulting in controlled expansion after hardening. This expansion compensates for volume changes due to temperature variations, moisture fluctuations, or drying shrinkage, reducing cracking and improving durability. Expansive admixtures are beneficial for concrete subjected to thermal stresses, restrained conditions, or where dimensional stability is crucial. They enhance concrete performance, mitigate cracking, and contribute to the longevity of structures.
