1. Juni 2023 As one important auxiliary, superplasticizers have attracted lots of attention in the concrete and building materials field. Specially, polycarboxylate superplasticizer (PCE) has been widely applied due to its relatively low doping amount, high water reducing rate and environmental friendliness property. In this review, the properties of

1. Juli 2022 Polycarboxylate ether superplasticizers (PCEs) are water reducers in the concrete mix that play a significant function in aspects of reducing the water-to-cement ratio, improving impermeability
20. Sept. 2020 In this study, the effect of polycarboxylate ether-based water reducing admixture (WRA) main chain length on fresh state properties, compressive strength, ultrasonic pulse velocity (UPV) and water absorption capacity of self-compacting concrete (SCC) mixtures were investigated. Within this aim, three polycarboxylate ether-based
Polycarboxylate ether (PCE) is a type of superplasticizer used in the production of high-performance concrete and dry mortar. This synthetic polymer is added to concrete and dry mortar mixes to improve their workability, reduce water content, and increase their strength and durability. Its increasing popularity in the construction industry is
30. Apr. 2018 To solve the problem of high viscosity for fresh concrete especially high-grade concrete, a novel viscosity-reducing type of polycarboxylate superplasticizer (PCE) was synthesized based on
20. Dez. 2021 Adsorption is commonly described as a surface phenomenon in which dissolved particles bind to the top layer of the solid surface [1].It is known that the spreading performance of polycarboxylate-based high range water-reducing admixtures (PCE), also known as superplasticizer, in cement paste is directly related with the adsorption
27. Juni 2022 The cement dispersion performance of a polycarboxylate (PCE)-based superplasticizer is highly related to their adsorption behaviors as a function of time. This study evaluated effects of PCEs on rheological properties of cementitious materials. First, characteristics of PCEs were characterized via permeation chromatography (GPC) and
