Illinois May 13, 2004c Copyright by Raissa Patricia Douglas 2001 All Rights ReservedAbstractSince the introduction of PC/kPortland Cement AssociationResearch s Development InformationPCA R&D Serial No. 2619Properties of Self-Consolidating Concrete Containing Type F Fl Properties of self consolidating concrete containing type f fly ash y gaining momentum. In the United States, the usage of see has been spearheaded by the precast concrete industry. Good see must possess the following key fresh properties: filling ability, passing ability, and resistance to segregation. In order to reduce segregation, see mixes are typically designe Properties of self consolidating concrete containing type f fly ash d with high powder contents, and contain chemical admixtures such as superplasticizers and viscosity modifying admixtures (VNÍA). This tends to increaProperties of self consolidating concrete containing type f fly ash
se the material cost of see. however one way to reduce the material cost is though adequate mix proportioning and rhe addition of supplementary cementPC/kPortland Cement AssociationResearch s Development InformationPCA R&D Serial No. 2619Properties of Self-Consolidating Concrete Containing Type F Fl Properties of self consolidating concrete containing type f fly ash an used. Incorporation of Class F fly ash in self-consolidating concrete as a means to replace portions of cement can decrease the cost of see, as well as further the sustainable development of concrete..An experimental program, aimed at investigating the behavior of see containing Class F fly ash h Properties of self consolidating concrete containing type f fly ash as been carried out. The fresh state properties of the concrete were assessed using methods of segregation and flow. The rheology of rhe paste matrixProperties of self consolidating concrete containing type f fly ash

Finally, some hardened state properties of the concrete were evaPC/kPortland Cement AssociationResearch s Development InformationPCA R&D Serial No. 2619Properties of Self-Consolidating Concrete Containing Type F Fl Properties of self consolidating concrete containing type f fly ash that could be used towards the commercialization of such a concrete. The results indicate that It is possible to develop a see containing Class F fly ash that IS high pel-forming 111 its flesh state. Furthermore, the addition of fly ash was shown to reduce supeiplasticizer dosage, increase workabili Properties of self consolidating concrete containing type f fly ash ty, and increase overall chloride permeability resistance In addition, it was determined that the difference of densities between the aggiegate and maProperties of self consolidating concrete containing type f fly ash
