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 …

Abstract Superplasticizer (SP), particularly poly-carboxylate based, can improve
substantially the strength-workability limits of cement powder paste by decreasing the water …

Superabsorbent polymers (SAPs) are a new, promising, multipurpose chemical admixture
for concrete. This article addresses the rheological behaviour of fresh, cement-based …

Abstract Effects of polycarboxylate (PCE) superplasticizers with different densities of
carboxylate groups, functional group contents, molecular weight, and side chain …

Shrinkage of concrete needs to be dealt with carefully in the design of reinforced concrete
(RC) structures as it creates dimensional instability and could induce excessive tensile …

Concrete should be flowable and cohesive to possess high passing ability. Adding
superplasticizer solely cannot increase the passing ability of concrete monotonically …

Shrinkage of concrete refers to the volumetric change of concrete due to cement hydration
(ie, self‐desiccation) and environmental drying (ie, water evaporation). It creates …

Nowadays admixtures and especially superplasticizers are unavoidable components of the
concrete formulation. The high fluidizing efficiency of the comb-like superplasticizers must …

Sodium gluconate is a commonly used retarder, and the incorporation of SG has been
accepted as the most efficient way to improve the basic performance of polycarboxylate …
