Abstract

Concrete with high compression strength is obtd. by mixing fine gravel possessing a high compression strength, sand, cement and water, the novelty being the use of a porous ceramic sand such as roasted clay having a grain size of 0.1-5mm and pores of 0.5-15 mu dia. which are larger than the size of the cement grains used. One pref. cement is CPA 400 HTS used with a sand having pores 0.5-2 mu dia. where 65% of the pores are 1-1.5 mu dia. Alternatively, cement CPA 400 is used with sand having pores 1-15 mu dia. where 60% are 5-10 mu dia.; 'Cement Pondu' may also be used with sand having pores of 1-15 mu dia. where 60% are 5-10 mu. The roasted clays are pref. kaolinic or illitic clays or marls. Artificial sand 0.1-5mm size may be used with porphyritic gravel, 5-18mm in size. Very high compression strength can be obtd. and the process is easily carried out on a construction site. Due to the strength, the size of concrete structures can be reduced.
