Title: Creep of Fly Ash Concrete
Author(s): Ram S. Ghosh and John Timusk
Publication: Journal Proceedings
Appears on pages(s): 351-357
Keywords: cement types; compressive strength; concretes; creep properties; fly ash; modulus of elasticity; shrinkage.
Abstract:The effect of different qualities of fly ash and different ash to cement ratios on creep, shrinkage, and modulus of elasticity for concretes with 20 MPa (3aK) psi) and 55 MPa (8000 psi) compressive strengths was determined. Results were compared with those for reference concretes of equal workability and 3- or 28-day strengths. Compared to reference concretes, it was found that concretes using fly ash of good quality had equivalent modulus of elasticity value and significantly lower creep and shrinkage. When borderline fly ash was used, the above properties were of comparable magnitude.
