The PDF file you selected should load here if your Web browser has a PDF reader plug-in installed (for example, a recent version of Adobe Acrobat Reader). One problem associated with using a high range water reducer in concrete is slump loss. Seven alcohols were combined with polycarboxylate superplasticizer and naphthene at a concentration of 0. 04N/mm 2 at 7days curing, while the compressive strength at the same percentage level of superplasticizer and water-cement ratio at 14 days curing ranged from 12. The fresh and hardened properties of waste virgin plastic mix concrete have been studied (CUR Report 1991). Navarro-Blascoa, J. This page was last edited on 21 May 2019, at 08:58. PROPERTIES • Admix CF 207 produces concrete of similar workability with 20%-25% less. Study on Synthesis and Properties of Low Sensitive Type Polycarboxylate. an approved superplasticizer to bring the slump back to within the specification. 02 at 20˚C. superplasticizer Spill or Leak Information: As in any fire, prevent human exposure to fire, smoke, fumes or products of combustion. de Brito a, ⇑ , L. Water reducers, retarders, and superplasticizers are admixtures for concrete, which are added in order to reduce the water content in a mixture or to slow the setting rate of the concrete while retaining the flowing properties of a concrete mixture. Sugiyama and Nakanishi, et al. Abstract This paper presents a preliminary work to evaluate the influence of slag and superplasticizer on the early-age hydration of cement pastes by an innovative non-contact impedance measurement, heat evolution method, compressive strength and setting time tests. 0% superplasticizer contents were prepared without change the water-cement ratio purposely to study the effects of superplasticizer to. 1 Curve D found to be 0.
