PEAT FLY ASH AS A SUPPLEMENTARY CEMENTING MATERIAL IN CONCRETE . NORDIC CONCRETE RESEARCH. PUBLICATION NO 7

The study was performed as a comparison test on superplasticized peat and coal fly ash concretes with or without an air-entraining agent. Reference concretes with pure portland cement were used. The fly ash contents varied between 20 -60 % by mass of the total amount of binder. The non-air-entrained concretes were used for studying the compressive strength, drying shrinkage, watertightness and water absorption properties. With the air-entrained concretes the frost-resistance properties were additionally studied by means of protective pore ratio, freezing dilation, freeze-thaw resistance and frost-salt resistance tests. The test data indicate that with proper mix design, and choice of admixtures, peat fly ash can be used as a supplementary cementing material to produce a high-quality, frost-resistant concrete.
