Influence of High-Porous Filling Materials and Mineral Fiber on Thermal and Fire Resistant Properties of Aerated Composites

Abstract:

Compounds were developed and properties studied of the composites on gypsum binding agent and light filling materials, exfoliated vermiculate and perlite providing high fire resistance to mortars on their base. The conducted selection of compounds with the use of a number of non-flammable fiber additives (fiberglass, chrysotile asbestos fiber) showed that the compounds with fiberglass additives had the biggest design quality ratio. The degree of influence of high-speed mortar mixture mixing on its properties was determined. Mixing speed increase up to 600 rpm allowed increasing of the design quality ratio for composites in average by 7-10%. Positive influence of fine-dispersed mineral additives (Cambrian loam, liquid perlite) on increase of retained strength of fire-resistant composites and screens after high-temperature tests was detected. Behaviour of fragments of fire-resistant screens on the basis of developed composites depending on their thickness and composition was studied at test unit providing temperature increase up to 1100°С within 180 minutes.
