RISEffect of Cement C3A Content on Properties of Cementitious Systems Containing High-Range Water-Reducing Admixture
Publisher: American Society of Civil Engineers
Abstract: The effect of cement tricalcium aluminate (C3A) content on the properties of cement paste, mortar, and concrete mixtures containing high-range water-reducing (HRWR) admixture was investigated. Three commercial Type I cements ...
Effect of Water-Reducing Admixtures Having Hybrid Silicon Air-Entraining Surfactants on Some Properties of Concrete Mixtures
Publisher: ASCE
Abstract: In order to improve the fresh properties and freeze-thaw resistance of cementitious systems, water-reducing and air-entraining admixtures are actively used in concrete mixtures. Generally, these mentioned admixtures are ...
Role of Anionic Group of Methylallyl Ether-Based PCEs on Behavior of Cementitious Systems with Various C3A Contents
Publisher: American Society of Civil Engineers
Abstract: In this study, the performances of methylallyl ether (HPEG) type polycarboxylate ether-based water reducing admixtures (PCE) partially substituted with phosphate and sulfonate anionic groups were investigated. The effects ...
Effect of Side Chain Length Change of Polycarboxylate-Ether–Based High-Range Water–Reducing Admixture on Properties of Cementitious Systems Containing Fly Ash
Publisher: ASCE
Abstract: In this study, the effect was investigated of side chain length changes of polycarboxylate-ether–based high-range water–reducing (HRWR) admixture on fresh properties, compressive strength, and water adsorption capacity of ...
Single and Multi Effects of Polycarboxylate Main and Side Chain Lengths on Setting Time, Viscosity, and Yield Stress of Cementitious Mixtures Containing Fly Ash
Publisher: American Society of Civil Engineers
Abstract: In this study, polycarboxylate polymers having different main chain lengths, side chain lengths, and main chain and side-chain lengths at constant molecular weight were synthesized. Cementitious mixtures with 0%, 15%, 30%, ...
