Advancements in concrete material sustainability : supplementary cementitious material development and pollutant interaction
Calcined clay and fly ash supplementary cementitious materials (SCMs) used in cement based materials were examined for their chemical and mechanical performance, as well as their pollutant interaction. This dissertation addresses three primary research questions, namely: (i) can zincite additions …

Strength prediction and durability performance of concrete containing coal bottom ash as supplementary cementitious material under aggressive environment
… than their projected service life. Therefore, Supplementary Cementitious Material (SCM) need to be introduced to improve the strength and durability performance of concrete. Besides that, prediction of concrete compressive strength is also an important aspect for the safety and quality control …

Unprocessed rice husk ash as a partial replacement of cement for low-cost concrete
… cement in-country to meet the demand for this material, and therefore it has to be imported. In rice-producing countries rice husk ash-a material naturally high in silica-can be used as a supplementary cementitious material and can substitute a portion of Portland cement in concrete without …

Investigation of Concrete Mixtures to Reduce Differential Shrinkage Cracking in Inverted T Beam System
… coarse aggregate (LWCA). Mixes with fly ash as supplementary cementitious material (SCM) developed smaller stresses at the bottom of deck when compared to mixes with slag as the SCM.

Nouveau système cimentaire cas de la Fritte de verre
… especially that of Quebec. A new-engineered material, known as glass fit (GF) has been developed through the chemical treatment of such waste. GF shows potential hydraulic and pozzolanic properties. GF has been studied as a binder itself and as a supplementary cementitious material (SCM). The …

The impact of natural and synthetic zeolite when used in cementitious based systems
… Portland cement, the most commonly used binding material in the construction and maintenance industry, is one of the principle carbon dioxide emission contributors. Indeed, up to 85% of the cement quantity produced is discharged into the atmosphere. As a result, efforts are being made to …

High Strength Pervious Concrete
… high-performance concrete in order to establish material specifications for pervious concrete. Additionally, the manufacturing of Portland cement produces significant carbon dioxide emissions, contributing to global warming and unfavourable climate change. To mitigate these environmental impacts, …

Advancing Lithium Extraction from Nevada’s Sedimentary Claystones: Hydrometallurgical Pathways and Sustainability Perspectives
… properties suitable for valorization as a supplementary cementitious material. A step back was taken to investigate the effect of including a physical beneficiation technique before leaching. Calcite in Nevada claystones represents a major processing challenge by driving excessive acid …

Practical Applications of Infrared, Raman and Nuclear Magnetic Resonance Spectroscopic Techniques for Qualitative, Quantitative and Structural Analysis of Pharmaceutical Drugs, Cementitious Material and Organic Molecules Containing Phosphorous
… explains the analysis of calcined clay as supplementary cementitious material, obtained from Ghana, a West African nation, which does not have an abundance of commonly used SCMs such as fly ash, silica fume, metakaolin, and slag. However, the abundance of clay minerals in the country could …

The productive reuse of coal, biomass and co-fired fly ash
… Therefore, this research examines their use as supplementary cementitious materials (SCMs) in concrete and as precursors for alkali-activated geopolymers. Toward their potential use as an SCM, after characterizing these ashes assessing their compliance with ASTM C618 requirements, their impact …
