In the last few decades, concrete industry has been massively expanded with adoption of various kinds binding materials. As a substitute to cement and in an effort relieve ecofriendly difficulties linked creation, utilization industrial waste as cementitious material can sharply reduce amount trash disposed lakes landfills. With respect mechanical properties, durability thermal behavior, ground...

The main objective of this research was to investigate the influence curing temperature on phase transformation, mechanical properties, and microstructure as-cured sintered kaolin-ground granulated blast furnace slag (GGBS) geopolymer. varied, giving four different conditions; namely: Room temperature, 40, 60, 80 °C. kaolin-GGBS geopolymer prepared, with a mixture NaOH (8 M) sodium silicate. sa...

The phosphorus (P) removal of five combinations of dual filters consisting of blast furnace slag (BFS), argon oxygen decarburisation slag (AOD) and electric arc furnace slag (EAF) was evaluated in column experiments with domestic waste water. The columns were fed with waste water for 24 days. The column with only EAF had the best P removal performance (above 93% throughout the experiment). The ...

The new Concrete Society Publication, Cementitious Materials, CSTR74, covers the effects of cementitious materials blast furnace slag (GGBS), fly ash (FA), limestone fines and silica fume (microsilica) on the properties of concrete. This paper focuses on the effects of silica fume on all the main properties of concrete in the fresh and hardened state as defined in the publication.

Alumina-rich iron ore is a widely existed polymetallic deposit in the nature, and it has a high comprehensive utilization value. Because the alumina and iron contents of alumina-rich iron ore vary from each other, there are many different measures and processes to recover iron and alumina from the various kinds of alumina-rich iron ore. In the blast furnace (BF) ironmaking process, the alumina ...

Ohio has substantial lands impacted by surface mining for coal and an active steel industry. Steel industry slags have been used as liming compounds for agriculture and acid mine soil reclamation. This 3-year study evaluates slags from Ohio steel mills in greenhouse trials where these materials are compared to reagent grade CaCO 3 in their ability to improve plant growth on acid mine soil. The ...
