EFFECT OF SLAG AND FLY ASH ON PROPERTIES OF CONCRETE.
(1987) T.P. Agrawal; P.K. Singh; M.L.K. Rao
Pure slag was mixed as 20%, 30%, 40% and 50% of the total cementitious material. Other proportions considered are 20% fly ash, 10% slag and 10% fly ash, and 15% slag and 5% fly ash. The consistency and setting times have been studied. Fly ash and slag increase the setting times. Slag reduces the normal consistency whereas fly ash increases it. At 56 days, concrete with 20% fly ash has strength that is comparable to ordinary concrete. Fly ash and slag give more strength to concrete when used separately.
