The coal briquette can be used for household alternative fuel. Burned the coal briquette will be produced ash.  The ash cause environmental pollutant. The ash can be used a part of sand substitute to make cement paste.  The research aimed to study the effect of percentage of ash (0, 10, 20, 30, and 40%) from sand that needed to make cement paste to strength of block cement and seepage water in cement.  The mixing of 10% ash in block cement can decrease 12,5% strength of block cement from maximum strength.  The mixing 10-20% ahs in block cement can restrain seepage water in block cement a boat 50%.  Keyword: Ash Coal Briquette, Cement, Strength and Seepage
