Concrete admixtures (additives) enhances the properties of concrete for applications in construction with special requirements. Concrete additives are used to achieve desired workability in case of low water cement ratio, and to …
Concrete admixtures are essential components used to enhance the properties of concrete mixes. This guide provides valuable insights into various types of concrete admixtures, their characteristics, European standards and applications.
Admixture, permeability-reducing – An admixture used to reduce the ingress of water and water borne chemicals into concrete. Admixtures may be further sub-divided into permeability …
Various types of admixtures are used in concrete to enhance the performance of concrete. Concrete admixture is defined as the material other than the aggregate, water and cement added to the concrete. Concrete admixtures are of different …
In particular, polymer additives seem to be a promising type of component that can significantly change concrete and mortar properties. Currently, the most popular polymer additives include superplasticizers, …
Influences of polymer nanoparticles (PNPs) with varied charge densities on the rheological behaviors of fresh cement pastes (fcps) without and with polycarboxylate …
Understanding the fundamental mechanisms of micro- and nanomaterial reinforcement and their application in designing advanced 3D printable concrete can provide valuable insights into the …
Self Compacting Concrete, Strength, Mineral Admixtures, Superplasticizers, Microstructure . Abstract: Self Compacting Concrete (SCC) Was Created Especially For Usage In Conditions …
A novel superplasticizer, polymer nano-particle (PNP) was put forward and synthesized. • PNP can adsorb on cement surface and improve the fluidity of fresh cement pastes. • PNPs' retardation effect on cement hydration is less significant than traditional PCEs. …
Chemical admixtures are used on a daily basis in the cast-in-place and precast concrete industries. Twelve categories of admixtures are described in detail as to type, current usage, …
