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 ...
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 ...
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%, ...
Fresh Properties and Fracture Energy of Basalt and Glass Fiber–Reinforced Self-Compacting Concrete
Publisher: ASCE
Abstract: In this study, the fresh properties, fracture energy, compressive strength, and flexural strength of self-compacting concrete including glass or basalt fibers were examined, and the effect of fibers on these properties ...
