Influence of Drying Protocol on the Setting and Crystalline Phase Formation of Calcium Silicate‐Based Sealers

Australian Endodontic Journal, Volume 52, Issue 1, Page 168-177, April 2026.
ABSTRACT The objective of this study was to assess the hydration, crystalline structure, and setting of bioceramic ready‐to‐use and powder/liquid sealers in dry and wet root canal dentine. Thirty‐two single‐rooted human teeth were embedded in acrylic resin and sectioned into 2‐mm segments.

Impact of different superplasticizers on hydration, rheology, mechanical strength, and environmental evaluation of LC3 cements

Case Studies in Construction Materials
The mineralogical and physicochemical characteristics of the clay can adversely affect the efficiency of polycarboxylate-based superplasticizers, limiting their dispersion capacity.

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 ...

Experimental data of cement grouting in coarse soils with different superplasticisers

Data in Brief, 2020
High-range water reducers, such as superplasticisers, can be potentially viable for cement grouting applications. In this study, we investigate the influence of two types of superplasticisers—one based on polycarboxylate ether and another based on ...

Introducing Pure Calcium Orthophosphate Gels and Aerogels

Advanced Functional Materials, Volume 36, Issue 23, 19 March 2026.
The synthesis of calcium phosphate‐based gels and aerogels is reported, which exhibit highly porous structures built up of networks of nanoparticles. In case of amorphous aerogels, this leads to yet unmatched specific BET surface areas, making these materials especially interesting for biomedical applications.

Structure and mineral composition of soil-cement with complex additive

Инженерно-строительный журнал, 2018
The effect of the polycarboxylate ether and the complex hydrophobic-plasticizing additive on the structure, phase and mineral composition of cement based on polymineral clay with content of relict minerals more than 85 % (52.49 % of quartz) was studied ...

Using Rubber Fillers to Fabricate Strain Gradient Material—An Excellent Approach for Developing High‐Toughness Cement‐Based Composites

Engineering Reports, Volume 8, Issue 3, March 2026.
Strain gradient cement‐based composites (SGCC) were fabricated by using rubber fillers in this study. This design of SGCC can realize the function of stress redistribution, multi‐crack dissipation, and efficient energy to improve the toughness of concrete structures.

Interaction between cements with different composition and superplasticizers

Materiales de Construccion, 2012
The slump behavior of ordinary Portland-, pozzolanic (red brick powder)-, sulfate resistant-, and limestone cement pastes caused by ≤ 1% additions of polycondensates and polycarboxylates superplasticizers are monitored for up to 90 minutes.
