Wet-Treated MSWI Fly Ash Used as Supplementary Cementitious Material

Advances in Materials Science and Engineering, 2015
Municipal solid waste incineration (MSWI) is a common technique in treatment of domestic waste. This technique annually produces approximately 25 Mt solid residues (i.e., bottom and fly ash) worldwide which is also a major issue in current research.

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.

Overview of clay as supplementary cementitious material [PDF]

5th Symposium on Doctoral Studies in Civil Engineering, 2019
Locally available materials, like clays, present a potential to meet the growing concrete demand and to produce more sustainable material. This paper reviews the behaviour of common clay minerals (kaolinite, illite and montmorillonite) giving an insight into the complexity of clay soils that usually appear as mixtures of minerals and impurities.

Application of Ceramic Powder as Supplementary Cementitious Material in Lime Plasters

Medžiagotyra, 2016
In this paper, the properties of plasters based on lime – brick powder binder of varying composition (ceramics content from 0 to 80 %) are studied. The plasters are prepared with a constant water amount. The pore size distribution is thus influenced in a
