Combined Effect of Photocatalyst, Superplasticizer, and
This study also explains why glass fiber fulfills the role of inner reinforcement only if a superplasticizer is simultaneously added to the gypsum matrix. It is possible, by the combined effect...
Evaluation of properties of gypsum plaster-superplasticizer
Superplasticizers are water reducing admixtures used to improve the flow ability of cementitious materials, resulting in enhanced mechanical properties of the hardened products. They comprise high molecular weight organic polymers containing several polar groups which render them water soluble.
Combined Effect of Photocatalyst, Superplasticizer, and Glass
In this study, gypsum plasters enriched with the modified photocatalyst TiO2/N and additive components were prepared and analyzed in detail. The aim of this work was to recognize the combined impact of a photocatalyst, polycarboxylic superplasticizer (SP), and glass fiber (F) on the properties of the composed building materials. The mutual compatibility was verified in relation to self
Minerals | Free Full-Text | Insight into Saturated Hydraulic
Recycling of tailings in the form of cemented paste backfill (CPB) is a widely adopted practice in the mining industry. Environmental performance is an important design criterion of CPB structures. This environmental performance of CPB is strongly influenced by its saturated hydraulic conductivity (permeability). Superplasticizers are usually added to improve flowability, but there is a
Superplasticizer for cement and gypsum Melment F10
Superplasticizer is especially optimized for plastification and water reduction of cement and calcium sulphate based materials. Superplasticizer provides an excellent development of early strength. Fields of application are : Self-levelling underlayments (SLU) Feather-edge products Non-shrink grouts Cementitious floor screeds
- Does superplasticizer improve gypsum hydration?
- These studies showed that superplasticizer accelerates the rate of hydration and leads to the formation of a dense and well compacted texture of crystals, thereby imparting high strength and better water resistance to the gypsum matrix than the reference material. 1. Introduction
- Which superplasticizer provides the strongest water resistance to gypsum products?
- From the observed results, it is confirmed that the most hydrophobic superplasticizer, PStSS-14 provides the strongest water resistance to the gypsum product. FT-IR results also support this observation (Fig. S10). It indicated that extended and strong water resistance of gypsum products can be achieved by properly designing a superplasticizer.
- Does superplasticizer add gypsum matrix?
- The reduction in water content and modification of β-calcium sulphate hemihydrate through superplasticizer addition which lead to a perceptible improvement in the strength of the plaster by intensification of gypsum matrix, contributed to this phenomenon.

- What is melflux ® superplasticizer?
- Melflux ® superplasticizers, which is applied during the gypsum wallboard production process, offer additional water reduction potential compared to standard superplasticizers. Due to less water in the stucco, customers can effectively reduce energy costs for evaporation of excess water.
- What is a superplasticizer & how does it work?
- The superplasticizers also known as fluidity enhancer has found to increase the strength and water resistance capacity of the gypsum matrix .
- Do superplasticizers adsorb gypsum crystals?
- Setting times of the superplasticized latex gypsum plaster. To confirm the adsorption characteristics of the superplasticizers on the gypsum crystals and their effects on setting time the adsorbed amount of superplasticizers by gypsum obtained from UV–visible spectroscopy are shown in Fig. 2.
