Development of Highly Water-Resistant Gypsum-Based Composites.

Gypsum Composites with CDW as Raw Material

Abstract—In this study, the feasibility of incorporating ceramic waste from bricks (perforated brick and double hollow brick) and extruded polystyrene (XPS) waste, is analysed. Results show that it is possible to incorporate up to 25% of ceramic waste and 4% of XPS waste over the weight of gypsum in a gypsum matrix. Furthermore, with the addition of ceramic waste an 8% of surface hardness incre...

Investigations on the Reinforcement of Mechanical Properties of Gypsum Composites Containing E-glass Woven Fabrics

Glass fiber reinforced gypsum composites are new building materials that have been used in covering interior walls. Reinforcement by means of woven fabrics as a three dimensional material is an alternative to the use of short fibers. The application of appropriate fabrics can improve mechanical properties of gypsum composites. The aim of this research article is to investigate the effect of the...

Development and characterisation of highly antibiotic resistant Bartonella bacilliformis mutants

The objective was to develop and characterise in vitro Bartonella bacilliformis antibiotic resistant mutants. Three B. bacilliformis strains were plated 35 or 40 times with azithromycin, chloramphenicol, ciprofloxacin or rifampicin discs. Resistance-stability was assessed performing 5 serial passages without antibiotic pressure. MICs were determined with/without Phe-Arg-β-Napthylamide and artes...

Advanced Radiation-Resistant Ceramic Composites

Ceramic matrix composites (CMC’s), particularly silicon carbide (SiC) fiber-reinforced SiC-matrix (SiC/SiC) composites, have been studied for advanced nuclear energy applications for more than a decade. The perceived potentials for advanced SiC/SiC composites include the ability to operate at temperature regimes much higher than heat-resistant alloys, the inherent low inducedactivation nuclear ...
