Presented within is a critical overview of the effect of sulfates on cement hydration,
properties, and optimum sulfate content in Portland cement. Calcium sulfate is used in …

Progress in understanding hydration is summarized. Evidence supports the geochemistry
dissolution theory as an explanation for the induction period, in preference to the inhibiting …

Polycarboxylate (PC) superplasticizers are being widely used in concrete mixtures due to
their high water reduction rate and good slump retention at low dosage. The chemical …

An understanding of the rheological behaviour of OPC-based products has been widely
studied, for it is essential to determining and predicting the fresh and hardened …

Recent advance on chemical admixtures and their influence on the concrete properties is
summarized. The conformational properties of PCE molecules both in solution and on the …

Tomorrow's mineral binders are called on to integrate a growing proportion of mineral
powders other than Portland clinker. This impacts most properties of industrial interest …

This research sheds light on the two origins of C 3 A hydration in structural build-up of
cement paste. The largest critical strain is associated with colloidal interaction, whereas the …

In this research, effects of polycarboxylate superplasticizers (PCEs) with various carboxylic
densities and functional groups on the adsorption behavior, dispersing performance as well …

The current study aims to construct a synthetic polymer (or family of polymers) with superior
plasticizing properties in a highly alkaline medium. An invented laboratory-prepared …

The effect of different types of superplasticizer on fresh, rheological and strength properties
of self-consolidating concrete (SCC) was investigated. The admixtures had same main chain …
