Comparative study between polymeric superplasticizers
Aguiar, J. L. Barroso de; Pires, Patrício; Machado, A. V.; Ferreira, Rui Miguel; Azevedo, IsabelThe present work aims to compare the properties of concrete produced with different incorporation of superplasticizers. Superplasticizers or water reducing agents are considered the most important chemical admixtures in concrete mixtures, due to their influence on the properties of both fresh and hardened concrete. Superplasticizers are usually polymer based products. Three superplasticizers were tested: two su...
Concrete workability and water resistance improvement using polymeric admixtures
Pires, Patrício; Azevedo, Isabel; Machado, A. V.; Aguiar, J. L. Barroso de; Ferreira, Rui MiguelThe present work aims to compare the physical and mechanical properties of concrete produced with different incorporation of polymeric admixtures. Two families of admixtures are studied: the superplasticizers and water resisting admixtures. The main results of the experimental program are presented and analysed. The performance of concrete incorporating admixtures is measured using physical and mechanical prope...
