The nucleation of C-S-H via prenucleation clusters

T. Sowoidnich et al.

Summary: The present study investigates the nucleation process of calcium-silicate-hydrate (C-S-H) in the aqueous phase of hydrating tricalcium silicate (C3S) using inductively coupled plasma-optical emission spectroscopy and analytical ultracentrifugation. The results reveal that the formation of C-S-H follows non-classical nucleation pathways involving the formation of prenucleation clusters (PNCs) of two types. These PNCs are accurately and reproducibly detected and consist mainly of ions (with associated water molecules). The study provides experimental data on the size, density, molecular mass, and shape of the detected species, and outlines possible aggregation processes.

A comparative study of the effects of two alkanolamines on cement hydration

Zichen Lu et al.

Summary: The effects of two alkanolamines, TEA and DEIPA, on cement hydration were investigated and compared using various techniques. The results show that the types and dosages of alkanolamines significantly alter the cement hydration regime, primarily through their impact on the aluminate reaction.

C-S-H-Polycondensate nanocomposites as effective seeding materials for Portland composite cements

Matthias Theobald et al.

Summary: This study presents the preparation, properties and accelerating performance of three different C-S-H-polycondensate nanocomposites in a fly ash-limestone blended composite cement. The formation of nanofoils via a non-classical nucleation mechanism, their effectiveness as seeding material and accelerator in the early stages of cement hydration, and a slight decline in final strength were observed. The polycondensate-based C-S-H seeds are attractive due to their universal availability, cost-effectiveness and easy preparation method.

Influences of PCE superplasticizers with varied architectures on the formation and morphology of calcium hydroxide crystals

Jian Wang et al.

Summary: This study investigates the impact of polycarboxylate (PCE) superplasticizers on calcium hydroxide (CH) precipitation and morphology, revealing that the presence of polymers significantly reduces the crystal size of CH and increases the specific surface area. Polymers with higher carboxylic group density have a stronger influence on CH precipitation, while the effect of solely sulfonic group charged polymers is negligible.

First Steps to Rationalize Host-Guest Interaction between α-, β-, and γ-Cyclodextrin and Divalent First-Row Transition and Post-transition Metals (Subgroups VIIB, VIIIB, and IIB)

Heloise Dossmann et al.

Summary: This study employs electrospray ionization coupled to mass spectrometry (ESI-MS/MS) and density functional theory molecular modeling to investigate the coordination of various metals with cyclodextrins. By screening a wide range of features related to the metal and the formed complexes, complex relationships between them are revealed.

Effect of a novel starch-based temperature rise inhibitor on cement hydration and microstructure development: The second peak study

Yu Yan et al.

Summary: The temperature rise inhibitor modifies the exothermic process of cement hydration and mitigates the buildup of cumulative heat to solve the thermal cracking issue. The second peak in heat release is mainly attributed to C3S hydration and the ongoing precipitation of ettringite helps to eliminate the restriction on C-S-H nucleation.

Effect of a liquid-type temperature rise inhibitor on cement hydration

Yu Yan et al.

Summary: The liquid-type temperature rise inhibitor (L-TRI) based on modified sorbitol was developed to modulate heat release from cement hydration and prevent thermal cracking. Testing results showed that L-TRI prolonged the induction period and reduced maximum heat flow, effectively inhibiting thermal cracking caused by cement hydration.

A new insight into the working mechanism of PCE emphasizing the interaction between PCE and Ca2+ in fresh cement paste

Hongwei Tian et al.

Summary: The dispersing efficiency of PAA, PCE polymers, and AA-co-AMPS copolymers in fresh cement pastes was studied with a focus on their interactions with Ca2+ ions. The presence of side chains in PCE polymers inhibited the ion-bridging effect, while AA-co-AMPS copolymers demonstrated strong resistance against ion-crosslinking effects.

Poly(Ethylene Glycol)/β-Cyclodextrin Pseudorotaxane Complexes as Sustainable Dispersing and Retarding Materials in a Cement-Based Mortar

Clotilde Capacchione et al.

Summary: Pseudorotaxane complexes between beta-CD and mPEG-COOH derivatives were synthesized and investigated for their dispersing properties in cement-based mortar. The complexes showed excellent dispersing abilities and a retarding effect in mortar tests, similar to other beta-CD-based superplasticizers.
