Do PCEs Adsorb Preferentially on OPC or Calcined Clay?

Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
ABSTRACT In multi‐component binders, admixtures such as polycarboxylates (PCEs) may exhibit preferential adsorption onto one component. Hence, for the first time PCE adsorption on ordinary Portland cement (OPC) and calcined clay (CC) in an OPC/CC blend was quantified by separating the OPC and CC particles from the hydrated cement employing a ...

Preliminary Study of the Pozzolanic Activity of Dumped Mine Wastes Obtained from the North Bohemian Basin in the Czech Republic

Medžiagotyra, 2017
Three dumped raw materials, a tuff and two bentonites, obtained from two mining sites at the North Bohemian basin in the Czech Republic, have been studied in order to evaluate them as pozzolanic admixtures in lime mortars for employment in restoration of

Incorporation of Coconut Fibers Into Clay‐Based Mortars: A Study on Mechanical and Microscopic Behavior

International Journal of Ceramic Engineering &Science, Volume 8, Issue 2, March 2026.
Clay‐based mortar reinforced with coconut fibers showed improved flexural strength and promising mechanical performance, despite shrinkage‐induced cracks. The study highlights the potential of using waste and natural fibers in eco‐efficient mortars, emphasizing the importance of curing and moisture control.

Industrial calcination of kaolinitic clays to make reactive pozzolans

Case Studies in Construction Materials, 2017
This paper presents the results of an industrial trial for the production of calcined clay to be used as pozzolan in cement manufacture. For the trial, a wet-process clinker rotary kiln was modified to process on dry basis the low grade kaolinitic clay used as raw material.

Improvements on Pozzolanic Reactivity of Coal Refuse by Thermal Activation

Environment and Pollution, 2012
Today, coal refuse as industrial solid waste stockpiled on the ground is one of the greatest threats to the environment. One of the practical solutions to utilize this huge amount of solid waste is to activate the coal refuse and utilize it as substitution for portion of ordinary Portland cement.
