20150315079 | FIRE RESISTANT CONCRETE - The present invention relates to improved concrete elements, particularly to high-performance self-compacting concrete (HP-SCC); to cementitious compositions suitable for producing such concrete elements; to methods of manufacturing such concrete elements and such cementitious compositions; to the use of specific additives in concrete elements and cementitious mixtures. The inventive compositions comprise an effective amount of polymer fibres and of hydrogels. The inventive concrete elements show improved fire resistance, particularly towards explosive spalling. | 11-05-2015 |
20140343183 | NOVEL PHOSPHONAMIDATES-SYNTHESIS AND FLAME RETARDANT APPLICATIONS - A group of novel compounds containing one or more amino substituted DOPO (9,10-dihydro-9-oxa-phosphaphenthren-10-oxide) moieties. The compounds were found to have good flame retardant properties and also good thermal stability, which makes them particularly suitable as flame retardant additives for various thermoplastic polymers. In particular, they can be incorporated in a polyurethane foam. | 11-20-2014 |
