Abstract: The durability of alkali-activated slag grouting materials (AASGMs) has attracted significant research attention. This paper investigated the mechanical properties and microstructure of AASGMs mortars and pastes immersed ...

Abstract: As a measure of total demand management, park and ride (P&R) has been widely used in Europe and North America and has been proved to be successful in mitigating congestion and difficulty of finding parking space in ...

Abstract: In this study, the changes in the phase and microstructure of alkali-activated slag (AAS) in ultralow-temperature environments (−170°C) was experimentally studied by means of X-ray diffraction (XRD), Fourier transform ...

Abstract: This research investigated the synergistic adoption of sodium silicate (SS) and the synthetic calcium silicate hydrates (C-S-Hs)/polycarboxylate (PCE) nanocomposites on the hydration behavior of portland cement containing ...

Abstract: To enhance the early strength development of lithium slag composite binder, synergistic action of calcium silicate hydrates (C─ S─ Hs)–polycarboxylate (PCE) and Al2(SO4)3 on the hydration properties of lithium slag–cement ...

Abstract: The Inner Tibetan Plateau (ITP; also called the Qiangtang Plateau) appears to have experienced an overall wetting in summer (June, July, and August) since the mid-1990s, which has caused the rapid expansion of thousands ...

Abstract: The addition of polycarboxylate superplasticizers (PCE) can alter the microstructure of dispersion system, and hence improve the fluidity of cement paste. In this paper, adsorption isotherms of PCE as well as the rheological ...
