Abstract:In a large castern housing project of two-story concrete buildings considerable trouble was experienced from the "dusting" of first floor ceilings which were poured against new pressed board forms. The experimental work to isolate the cause, the results of the test and their interpretation indicated that the dusting was caused by an acidic resinous substance in the surface of the form board. The substance on the surface of the board appeared to be neutralized when the form was used for the first time, inasmuch as reused form boards gave little trouble. In concluding, the author recommends that new types of form material be checked for possible chemical reaction before use in large amounts.
