RISEffects of Polycarboxylate Superplasticizers with Different Functional Units on Early Hydration Behavior of Cement Paste
Publisher: American Society of Civil Engineers
Abstract: Effects of polycarboxylate superplasticizers (PCEs) with different functional units on the flowability, hydration heat, and hydration products of cement paste were investigated. Two kinds of functional units, the sulfo ...

Study on Ions Leachability and Microstructure of FGD Gypsum–Based Material Mixed with Cement and Slag by Isothermal Calorimetry and Low-Field Nuclear Magnetic Resonance
Publisher: ASCE
Abstract: Flue gas desulphurization (FGD) gypsum is a kind of industrial solid waste containing impurities (i.e., heavy metal ions Zn2+ and Ni2+), which may lead to threats to the ecological environment and public health. To ...
Influence of Copper Slag on Mechanical Performance, Hydrate Assemblage, and Mechanism of Cementitious System
Publisher: ASCE
Abstract: Copper slag (CS) is a by-product generated during the process of copper metal smelting. The influence of CS on the mechanical performance, hydrate assemblage, and mechanism of the cementitious system was investigated by ...
Properties and Microstructure of Alkali-Activated Slag Paste Modified by Superabsorbent Polymers
Publisher: ASCE
Abstract: Superabsorbent polymers (SAPs) can serve as effective internal curing agents in alkali-activated slag (AAS) systems, mitigating the risk of cracking. However, the influence of SAPs on the properties and microstructure of ...
NMR Study on the Pore Structure Development of Cement Paste with Bleeding during Hydration
Publisher: ASCE
Abstract: Previous studies focused on the determination and simulation of the bleeding extent of fresh cement paste and provided objective conclusions. However, few studies exist on the influence of bleeding on the final structure ...
The Influence of Water-Repellent Admixtures on the Hydration Process, Water Absorption, and Mechanical Properties of Cement Paste: An NMR Study Combined with Additional Methods
Publisher: ASCE
Abstract: Water repellent (WR) has been widely used to improve the durability of cementitious materials (CMs) by reducing the absorption of water and aggressive ions. In this study, cement pastes were prepared with three types of ...
