Synthesis and Properties of a Polycarboxylate Superplasticizer with a
Polycarboxylate superplasticizers (PCEs) are comb-shaped polymers with an anionic backbone and several nonionic pendant chains, which typically are comprised of polyethylene glycols. In this study, the synthesis of a new type of superplasticizer is presented, which does not exhibit the typical comb-shaped form of PCEs but is built up from a linear polyetheramine and a hyperbranched
Effectiveness of Thermal Stimulation of Superplasticizers on Fresh
Polycarboxylic acid-based superplasticizers are used in various types of concrete work. Wide variations in environmental temperatures are known to affect how well chemical admixtures perform as superplasticizers, influencing the properties of the concrete. However, little has been reported on changes in performance caused by thermal variations. Previous studies have reported that heating
Polycarboxylate Superplasticizers | Supercizer PCE | Fritz-Pak
Polycarboxylate superplasticizers are a fairly recent development in the concrete admixture industry. This unique blend of water-reducing chemicals provides substantially more benefits than previous superplasticizers. In fact, Fritz-Pak’s Supercizer PCE provides up to 40% water reduction and up to an eight-inch slump reduction in most
Concrete Radiation Resistance Dependency on Phase
In this paper, the mechanism of the influence of polycarboxylate superplasticizers on the process of phase formation in hardened cement paste (HCP) and its effect on the stability of the cement matrix during radiation-thermal changes is researched in more detail. 2 Methods The method of X-ray diffraction analysis (XRD) was chosen for the research.
Polycarboxylate and polyether admixture compatibility with different
The effect of polycarboxylate (PC) superplasticizers with different structure on the rheological properties and hydration process of slag-blended cement pastes with a slag content between 0 and 75
