Pozzolanic Activity of Concrete Incorporated Sustainable Materials for Rigid Pavements
Many scholars worked on utilizing byproducts materials in rigid pavements because of the increasing demand for incorporating sustainable pavement materials in construction. Ceramic is one of the materials integrated to the concrete mix as a cement alternative. Recently, it has been witnessing a debate on whether it is considered pozzolanic. In line with this trend, this study aims at first in assessing the pozzolanic activity of ceramic powder and the hybrid powder composed of ceramic and slag cement as well as assessing the flexural capacity of concrete. The adopted research program made on pastes is achieved through Frattini test (direct method) and strength activity index (indirect method) along with SEM and X-ray diffraction tests to characterize the studied pastes. Four types of pastes are considered in the experimental plan: cement paste, slag cement paste, ceramic cement paste, and a hybrid paste which consists of ceramic, slag, and cement. Lastly, the flexural capacity is made through the four combinations. The accomplished laboratory-testing program is presented, and the results will be further analyzed and discussed.
