Sulfur speciation in untreated and alkali treated ground-granulated blast furnace slag [PDF]

Science of The Total Environment, 2017
Reduced sulfur species in ground-granulated blast furnace slag (GGBFS) play an important role in immobilizing radionuclide contaminants in caustic cement-GGBFS mixtures via reductive precipitation reaction. However, sulfur (S) speciation and its stability in GGBFS have not been clearly understood.

Strength, Sulfate Resistance, and Microstructural Characteristics of Concrete With Partial Cement Replacement Using Eggshell Powder and Wheat Straw Ash

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
This study explores the partial replacement of ordinary Portland cement (OPC) with a composite of eggshell powder (ESP) and wheat straw ash (WSA) in C‐25 concrete, focusing on mechanical performance and durability. Cement was replaced with varying proportions of ESP and WSA, and the concrete mix was prepared following ACI guidelines.

Durability Properties and Microstructure of Ground Granulated Blast Furnace Slag Cement Concrete [PDF]

International Journal of Concrete Structures and Materials, 2014
Ground granulated blast-furnace slag (GGBS) is a green construction material used to produce durable concrete. The secondary pozzolanic reactions can result in reduced pore connectivity; therefore, replacing partial amount of Portland cement (PC) with GGBS can significantly reduce the risk of sulfate attack, alkali–silica reactions and chloride ...

Stone‐Cutting Dust as a Sustainable Supplementary Cementitious Material: A Comprehensive Review of Its Physicochemical and Mechanical Effects

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Ordinary Portland cement (OPC) remains the most common binder used in construction and accounts for nearly 7%‐8% of the world’s CO2 emissions due to calcination of limestone and high energy use during clinker production. Reducing OPC content using SCMs is one of the major strategies to achieve sustainable construction.
