Abstract

"Concrete specimens were fabricated for shrinkage, creep, and abrasion resistance testing. Variations of self-consolidating concrete (SCC), high volume fly ash concrete (HVFA), and conventional concrete were studied. The results were compared to previous similar testing programs and used to determine the adequacy of the materials for use in practice. These two concrete variations offer significant benefits when used as replacements to conventional concrete. Because of the respective properties of both types of concrete, both economic and environmental benefits are achieved with the use of both. The lower labor costs of SCC and the lower material cost of HVFA lead to lower overall construction costs, while the decrease in CO₂ production and conservation of landfill space through the use of HVFA lead to significant environmental benefits. The SCC testing program consisted of normal strength (6000 psi) and high strength (10,000 psi) variations of SCC and conventional concrete. The HVFA testing program consisted of two variations of HVFA with 70% fly ash replacement and one conventional concrete mix. All specimens were tested for compressive strength, modulus of elasticity, shrinkage strain, creep strain, and abrasion resistance. All tests were performed according to their respective ASTM standard methods. SCC performed well relative to convention concrete at high strengths, but not as well at normal strengths for shrinkage and creep. HVFA, however, outperformed conventional concrete in both shrinkage and creep. Abrasion resistance was primarily dependant [sic] on concrete strength, not concrete type"--Abstract, page iii.
