16. Abstract

On December 14 and December 15, 2020, the Federal Highway Administration's (FHWA) Office of Infrastructure Research and Development held a virtual workshop called "Machine Learning and Pozzolans for Concrete Infrastructure Materials" with 80 participants in attendance. The workshop, consisting of eight presentations, largely focused on three ongoing Exploratory Advanced Research Program projects and one National Cooperative Highway Research Program project related to the pressing issue of finding new sources of supplementary cementitious material (SCM) for use in concrete for our Nation's roadway infrastructure.

For decades, fly ash, a by-product of coal plants' power-generating process, has been an important source of SCM for highway infrastructure concrete, enhancing the performance, economic feasibility, durability and sustainability of cement mixtures containing ordinary portland cement. As a result of environmental regulations and a general transition of power utilities' fuel source from coal to natural gas in recent years, high-quality fly ash has become increasingly scarce. In response, FHWA organized a workshop to illustrate ongoing research related to the pursuit of fly ash alternatives to ensure the sustainability of our Nation's roadway infrastructure.
