Road (klinkernyj) a brick develop from refractory glin, burning them before sintering. The road brick has the size 220X110X65 or 220X110X75 mm, Ðœ400, Ðœ600 and Ðœ1000, vodopog-loshchenie 2-6%, frost resistance of 30-100 cycles of alternate freezing and thawing. This brick can be applied for moshchenija roads and sidewalks, the device of floors of industrial buildings, a laying of sewer collectors. ó âàñ îñòåîõîíäðîç? âàì ñþäà - Ëå÷åíèå îñòåîõîíäðîçà
Fire-resistant name the products applied to building of industrial furnaces, fire chambers and the devices working at heats. Fire-resistant products classify on fire resistance, porosity, himiko-mineral structure and a way of manufacturing. Products fire-resistant are characterised by fire resistance 1580-1770°С, vysokoogneupornye - 1770-2000°С, the higher fire resistance - more 2000°С.
Depending on porosity (in%) fire-resistant products are subdivided into following groups: osoboplotnye - porosity less than 3, high density - 3-10, dense-10-20, usual - 20 30, superficial and teploizoljatsionnye - 45-85.
The Greatest distribution to building and the industry of building materials have received kremnezemistye and aljumo-silicate fire-resistant products.
Kremnezemistye ogneupory apply two types: quartz glass and dinasovye.
Quartz glass produce casting from the fused quartz, it contains JUg not less than 99%. Possesses good thermal stability and kislotostojkostju; at HOO! iC rassteklovyvaetsja also crumbles.
