    The waste of an industrial process that becomes serious problem is the increasingly accumulating sludge fly ash of PT Tjiwi Kimia. The sludge fly ash that physically resembles sand is used as an additive of sand in making paving blocks. The research method is based on SNI 03-0691-1996, the quality and and the test mode are obtained by adding 0%,20%,30%,40% of sludge fly ash into the mixture of 1PC : 4 rock ash : 4 gravel : 4 sand and 1PC : 3 rock ash : 3 gravel : 3 sand. The speciment of mortar with 5x5x5 cm size, and the paving block with a dimension of L=21cm, W=10,5cm, H=6cm. The compression strength test made on 7 and 28 days old. The research indicates that the highest value ov compressive strength is obtained from the mixture composition of 1PC : 3 rock ash : 3 gravel : 3 sand on the addition of 20% sludge fly ash with an average of compressive strength ammounting to 304,07 Kg/Cm2. The mixture mix conforms with the quality-standard requirement of the paving block with B quality classification on SNI SNI 03-0691-1996. Key words : Paving block, Pressure Strength test ; Fly Ash Sludge, Infiltation Test
