PROPERTIES OF LIGHTWEIGHT AGGREGATE MADE FROM DISCARDED ASBESTOS AND SLUDGE, AND PROPERTIES OF CONCRETE USING THIS AGGREGATE

Experiments were conducted on the physical properties of lightweight aggregates using discarded asbestos and sludge, and on the properties of concrete using these aggregates. I got the following results. (1) The density of aggregate A, a was approximately 0.9, the 24-hour water absorption rate was approximately 17%, and the BS10% crushing value was approximately 40 kN. (2) Concrete using aggregate A had a gradual increase in compressive strength as the cement-water ratio increased and the age of the material increased. (3) Concrete using Aggregate A exceeded the demolding strength specified in JASS14.
