Description:
The main purpose of this research is to investigate the minimum cementitious content required with an appropriate water to cementitious ratio (w/cm) to meet given workability, strength, and durability requirements in a rigid pavement; and so to reduce carbon dioxide emissions, energy consumption, and costs. This paper will present an experimental program that was conducted on 32 concrete mixtures. Sixteen mixtures were prepared using ASTM Type I ordinary portland cement and 16 contained ASTM C618 class C fly ash at 20% of portland cement replacement level. The test results showed that strength is a function of w/cm and independent of the cementitious content after the required cementitious content is reached, for a given w/cm. Based on the findings, for the aggregate system used in this work, it is possible to reduce the cementitious content without sacrificing the desired strength and durability of rigid pavements, for a given w/cm.
