Effect of alkali contents, moduli and curing time on engineering properties of alkali activated slag
, 2020Cement industry has become one of important sources of greenhouse gas emission. Compared with the cement, alkali activated slag (AAS) possesses comparable mechanical properties and lower carbon emission during its production.

Effect of recycled fine aggregates on alkali-activated slag concrete properties
, 2021Normally, recycled fine aggregate (RFA) is an unwanted by-product of construction demolished waste crushing, with high contaminant content. The presence of RFA is highly restricted in ordinary Portland cement (OPC) concrete production because of the poor

A parametric study of accelerated carbonation in alkali-activated slag
Cement and Concrete Research, 2021Resistance to carbonation is one important attribute that low-CO2 cement alternatives must possess, and is particularly crucial for cement alternatives subjected to aggressive CO2 concentrations such as those used in construction of oil wells and wells ...

Chemo-mechanical properties of alkali-activated slag/fly ash paste incorporating white mud
Construction and Building Materials, 2021White mud (WM) is a waste solid from paper industry. It mainly contains calcium carbonate and residual alkali metal ions (e.g., K+, Na+ and Mg2+). The aim of the study was to test the feasibility of incorporation white mud into a blended slag/fly ash ...

The influence of steel slag and ferronickel slag on the properties of alkali-activated slag mortar
Construction and Building Materials, 2019Abstract With the continuous development of industry, a huge amount of industrial wastes have been produced and caused severe environmental problems. In order to reduce the issue caused by industrial waste, in this investigation, 50 wt% ground granulated blast furnace slag (GGBS) replaced by steel slag (SS) or ferronickel slag (FNS) was used to ...

Immobilization of mercury and zinc in an alkali-activated slag matrix
Journal of Hazardous Materials, 2003The behavior of heavy metals mercury and zinc immobilized in an alkali-activated slag (AAS) matrix has been evaluated using physical property tests, pore structure analysis and XRD, TG-DTG, FTIR and TCLP analysis. Low concentrations (0.5%) of mercury and zinc ions had only a slight affect on compressive strength, pore structure and hydration of AAS ...
