Mechanically activated mine tailings for use as supplementary cementitious materials [PDF]
RILEM Technical Letters, 2021 Two mine tailings are evaluated for their potential as supplementary cementitious materials. The mine tailings were milled using two different methods – ball milling for 30 minutes and disc milling for durations ranging from 1 to 15 minutes. The modified

Physical characterization methods for supplementary cementitious materials [PDF]
Materials and Structures, 2014 The main supplementary cementitious materials (SCMs) that are used today are industrial by-products. In most cases the quality of these materials cannot be controlled during their production, resulting in materials with varied characteristics. The adequate physical characterization of SCMs is important to better predict their performance and optimize ...

A study of chloride binding capacity of concrete containing supplementary cementitious materials. [PDF]
Sci RepChloride-induced steel corrosion is known to be a very common kind of deterioration of reinforced concrete. It is beneficial to bind free chloride ions to reduce the corrosion probability of the reinforcement embedded in the concrete.

Vegetable ashes as Supplementary Cementitious Materials [PDF]
Cement and Concrete Research, 2018 [EN] Approximately 140 billion metric tons of biomass are produced every year in the world from agriculture. The ashes resulting from firing agricultural wastes such as rice husk, sugar cane and others can be used as Supplementary Cementitious Materials (SCM). They can be mixed with lime alone or in ternary mixtures with Portland cement and lime.
