The results also suggested that the maximum replacement ratio of PET powder should be less than 10% of the binder (by mass) to minimize its influence on cement hydration, due to the interaction between water and PET. The PET-containing samples showed the presence of calcium aluminate hydrates which were absent in the neat paste sample.

MACRO DEFECT FREE CEMENTS: A REVIEW

Brasov, Romania The usage of polymers in different sectors has been increasing in recent decades, and even our current age may have been defined as polymer age. When concrete is considered polymers are also widely used to modify the properties of both mortar and concrete and the usage of polymers in concrete dates back to 1920’s. On the other hand, Macro-defect free (MDF) cements …

Calciumaluminate – Wikipedia

Calciumaluminate sind Verbindungen von Calciumoxid (oder Calciumhydroxid) und Aluminiumoxid (oder Aluminiumhydroxid) von unterschiedlicher Zusammensetzung.Sie spielen in der Bauchemie als reaktive Verbindungen eine große Rolle und sind als wasserfreie Oxide Bestandteil von Zementen.Grundsätzlich gibt es gebrannte (gesinterte) Calciumaluminate …

Geopolymer, Calcium Aluminate, and Portland Cement-Based

In this paper, we comparitvley studied acetic acid attacks on geopolymer (GP-M), calcium aluminate (CAC-M), and Portland cement (PC-M)-based mortars. Consequent formations of deteriorated or transition layers surrounding the unaltered core material was classified in these three mortars, according to different degradation levels depending on what binder type was …

The influence of ethylene vinyl acetate and vinyl acetate

15.11.2018· The polymer materials in calcium aluminate cement based mixtures have deceleration effect on cement hydration which results in lower compressive strengths compared to the plain mixture, which this effect is more evident at higher replacement levels. Despite the considerable reduction in compressive strength results at early ages especially for the mixtures with high contents of polymers…
