Characterization of poultry litter ashes as a supplementary cementitious material

Case Studies in Construction Materials, 2022
In the present work, the possibility of using poultry litter ash (PLA) as a supplementary cementing material (SCM) is presented. Its physicochemical and microstructural parameters were determined and correlated to compressive strength.

Limestone-Calcined Clay (LC2) as a supplementary cementitious material for concrete

RILEM Technical Letters, 2023
In this work, limestone-calcined clay (LC2) is studied as an alternative supplementary cementitious material (SCM), combining two widely available resources – calcinated kaolinitic clay and limestone, to partially substitute portland clinker.

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 ...

Calcium oxychloride formation in pastes containing supplementary cementitious materials: Thoughts on the role of cement and supplementary cementitious materials reactivity

RILEM Technical Letters, 2016
Over the last decade many concrete pavements in North America have begun to show excessive damage at the joints. This damage appears to be due to two primary causes: classic freeze-thaw damage due to local saturation caused by the pooling of water at the

Reutilization of Ceramic Waste as Supplementary Cementitious Material

, 2023
The production of Portland cement (PC) has the highest environmental impact among the different components of concrete. Also, although ceramic prod-ucts are consumed worldwide and constitute a significant fraction of construction and demolition waste, significant amounts of ceramic waste (BCW) are simply landfilled or used as road sub-bases.

Re-use of Natural Clayey Waste as Supplementary Cementitious Material

Chemical Engineering Transactions, 2019
In 2015 total world cement manufacture was estimated at 4.6 billion tons and the CO2 emissions from cement plants were equal to approximately 3.7 billion metric tons, representing about 7% of the global anthropogenic emissions.

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.
