摘要：
Basic mechanical and hydric properties of alkali-activated aluminosilicate composite with electrical porcelain aggregates are investigated in dependence on previous thermal load up to 1200 degrees C. The compressive strength is found to increase by a factor of two after heating to 1200 degrees C, the bending strength even by a factor of six compared to the reference measurements on specimens not subjected to any thermal treatment. Water and water vapor transport is enhanced after heating to 600 degrees C and more. These results can be considered as quite advantageous for a material which can supposedly be used as protective layer of current reinforced concrete structures. (c) 2007 Elsevier Ltd.
