Poor durability of reinforced concrete structures can lead to serious structural failures. An accurate model observe the effects aggressive agents like carbonation, sulfate ingress, and seawater solutions on solid phase assemblage will help designers specifiers better understand how cement behaves in these environments. This paper presents first steps developing such a using PHREEQC geochemical...

This study evaluated tristrontium aluminate (S3A) and its viability as a component for tricalcium silicate (C3S) cements. The properties of S3A, C3S, S3A/C3S mixtures were in terms setting time, compressive strength, flowability, radiopacity. X-ray diffraction (XRD) pattern verified the powder synthesized laboratory consequently, confirming preparation method. S3A exhibited lowest followed by C...

BACKGROUND Classic self-curing temporary cements obstruct the translucence of provisional restorations. New dual-cure esthetic temporary cements need investigation and comparison with classic cements to ensure that they are equally retentive and provide adequate translucence. The objective is to analyze by means of traction testing in a in vitro study the retention of five temporary cements. ...

The utilization potential of citric acid, sodium tetraborate decahydrate and triphosphate pentabasic to control fresh state properties silicate-activated alkali-activated slag cements (AASC) has been studied. early structural build-up, reaction kinetics, pore solution chemistry, setting behavior, hardened such as microstructure, structure, mechanical AASC with these chemicals were investigated....

Integrated spectroscopic analyses and synchrotron X-ray microdiffraction investigations provide insights into the long-term reactivity of volcanic aggregate components calcium-aluminum-silicate-hydrate (C-A-S-H) binder in mortar samples from robust concrete sepulchral corridor Tomb Caecilia Metella, 1st C BCE, Rome. The results innovative micrometer-scale analytical maps indicate that Pozzolane...

OBJECTIVE The aim of this study was to compare the cytotoxic effects of endodontic cements on human tooth germ stem cells (hTGSCs). MTA Fillapex, a mineral trioxide aggregate (MTA)-based, salicylate resin containing root canal sealer, was compared with iRoot SP, a bioceramic sealer, and AH Plus Jet, an epoxy resin-based root canal sealer. MATERIAL AND METHODS To evaluate cytotoxicity, all mat...

INTRODUCTION The purpose of this study was to compare the push-out bond strength of white ProRoot Mineral Trioxide Aggregate (MTA), Biodentine, calcium-enriched mixture (CEM) cement and Endosequence Root Repair Material (ERRM) putty after exposure to blood. METHODS AND MATERIALS A total of 96 root dentin slices with a standardized thickness of 1.00±0.05 mm and standardized canal spaces were r...
