Functional properties of vegetal concretes, such as hygrothermal and acoustical properties, are brought by the microstructure particles. However, data necessary to develop biobased insulation materials providing results on their long-term behaviour, only few studies focus this topic. A first step is characterise behaviour aggregates in bulk. In study, hemp shiv stored for two years three different conditions: a static environment used reference, accelerated aging conditions based...
Based on previous works polymers and regular bitumens, a new method for determining the molecular weight distribution (MWD) of asphaltic paving binders, using phase angle () complex modulus measured in linear viscoelastic domain, has been developed this paper. MWDs pure petroleum natural modified bitumens artificially aged are calculated by compared with obtained gel permeation chromatography. The two methods give comparable results, but δ-method here is more sensitive to species. This very...
This work focuses on the molecular structure evolution of asphaltite-modified paving bitumens during ageing. In order to quantify effect ageing weight distribution (MWD) bitumens, a new parameter, called hereafter molecular-distribution shift (AMDS), is introduced. The evolutions aging are compared with pure petroleum equivalent grade. results based AMDS confirm previous research showing that asphaltite attenuates and, hard produced in refinery, present better performance. parameter reveals...
Biobased materials are increasingly being used for building insulation. Hemp concrete is an efficient thermal insulation material containing renewable resources, providing living comfort thanks to its acoustical and hygrothermal properties. In this study, two hemp ‘wall’ formulations manufactured with the same type of shiv commercial binders: natural cement a lime-based formulated binder. Ninety days curing (65% RH – 20 °C) ensure hardening materials. Mortars made up simultaneously control...
Abstract Polypropylene (PP) samples stabilized by a hindered phenol (Irganox 1010) were submitted to thermal ageing at 80°C in air atmospheric pressure or pure oxygen 5.0 MPa pressure. Both the polymer oxidation and stabilizer consumption monitored Infrared spectrometry analysis. The efficiency, as assessed ratio induction time/stabilizer concentration is almost constant even when higher than its solubility limit PP (0.4% 24 × 10 −3 mol L −1 ). In contrast, high pressure, efficiency...
