Results of laboratory tests indicate the strength that can be obtained when various amounts of Chicago fly ash are used in concrete mixes under various conditions. Results of a group of freezig and thawing tests show that air-entrained concretes made with and without Chicago fly ash are equally frost resistant. Chicago flky ash made in concrete with Type I portland cement increased resistance to attack by sulfuric acid. The tests were confined to fly ash from one electric utlilty company in Chicago and are not necessarily applicable to fly ashes from other sources.
