"Concrete is one of the most produced and utilized materials in the world. Due to the labor intensive and time consuming nature of concrete construction, new and innovative concrete mixes are being explored. Self-consolidating concrete (SCC) is one such method of improving the overall cost and time efficiency of concrete production. SCC is a highly flowable form of concrete. This characteristic drastically reduces the amount of labor and time needed to place the concrete. The highly flowable nature also allows for much easier placement in applications of highly congested reinforcement.
Another rising concern in today's construction industry is environmental responsibility. The addition of fly ash is a leading innovation in sustainable design of concrete. Fly ash, a waste by-product of coal burning power plants, can be used to replace a portion of the Portland cement in concrete. Investigators are pushing for higher and higher total replacement levels in what is known as high-volume fly ash (HVFA) concrete. However, minor issues observed with lower fly ash replacement levels may be exacerbated as the levels increase.
In order to test both innovative concrete mixes, SCC and HVFA concrete was tested for both hardened material properties and durability in this investigation. The results indicated that SCC, with its time saving capabilities, was superior to conventional concrete, while HVFA concrete was comparable to conventional concrete in all areas except compressive strength"--Abstract, page iii.
