Lightweight Concrete Containing Recycled Plastic Aggregates

Alqahtani Fahad K., Ghataora Gurmel, Khan M. Iqbal, Dirar Samir, Kioul Azzedine, Al-Otaibi Mansour
The concrete industry needs millions of tons of aggregate, comprising natural sands and gravels, each year. In recent years there has been an increasing trend towards use of recycled aggregate to save natural resources and to produce lightweight concrete. In this investigation, an attempt was undertaken...

Effect of Layer Shifting on the Out-of-Plane Permeability of 0°/45° Alternative Multilayer Fabrics

Liangchao Fang, Jianjun Jiang, Junbiao Wang, Linchao Zhou
The shifting of layers has great effect on the permeability which is a key parameter in resin transfer molding (RTM). In this paper, a mathematical model was developed to predict the out-of-plane permeability of 0°/45° alternative multilayer fabrics with one extreme structure. The global permeability...

The Preparation of Polypyrrole / Cellulose Acetate Composite Films and their Electrical Properties

Longning Suo, Xiuli Shang, Rongping Tang, Yanqing Zhou
A new method was developed for directly preparing conductive polypyrrole (PPy)/cellulose acetate (CA) composite films by in-situ chemical polymerization. The surface morphology of the films was observed by the atomic force microscopy (AFM). It was found that the composite films were composed of two layers...
