<p>PROBLEM TO BE SOLVED: To produce an inexpensive paving block low in water absorption. SOLUTION: In this method for producing the paving block low in water absorption, a compact obtained by mixing and kneading an aggregate consisting of 10-30wt.% aggregate particle having >=1mm grain size and 90-70wt.% aggregate particle having <=1mm grain size and a binder as an indispensable constituents and subjecting to press forming is burned. In such a case, the binder is either one among (a) a porcelain raw body and either one of a bentonite or a refractory clay or both, (b) a miscellaneous clay and either one of the bentonite or the refractory clay or both and (c) either one of the refractory clay or a fly ash, and a water content of the compact is 3-10wt.%.</p> |
