Badania wyrobów silikatowych w kierunku poprawy izolacyjności termicznej

The test results of ultimate compressive strength of silicate products containing exclay filler is presented. Silicate products have a high thermal conductivity λ. Their production is the most ecological technology among the manufacturing of wall elements. To improve the thermo-insulating characteristics of silicate products (parallel to preserving their ecologicness), the use of exclay filler is suggested. The tests of ultimate compressive strength were carried out for the wall silicate element (hollowed) with the size of 250x150x220 mm of 15th grade with 10%, 15% and 20% contents of exclay aggregate with 4-10 mm grading. The research helped to calculate the insulation index for the standard (N15) and insulating products
