DescriptionThe purpose of this study is to investigate the applicability of Type IL Portland Limestone cement for bridge deck and accelerated construction applications as a replacement of the traditional Type I/II cement. Traditional cement production contributes to a significant percentage of the total carbon emissions produced worldwide. According to the International Energy Agency (IEA), in 2020 an estimated 4.3 gigatons of cement had been produced globally, 0.59 tons of carbon dioxide (CO2) were produced for every ton of cement. For this reason, more research of Type IL Portland Limestone cement (PLC) is required especially that this type of cement produces 10% less carbon emission during production compared to traditional cement and is readily available. This is because PLC consists of 5-15% of limestone while Type I/II cement contains around 5%. In this study, the author evaluates strength and durability properties of the concretes in accordance with several ASTM and AASHTO testing standards. These tests include compressive strength, tensile strength, elastic properties, flexural strength, surface resistivity, rapid chloride permeation, and multiple types of shrinkage. Furthermore, restrained shrinkage test in accordance with AASHTO T334 is conducted for Type IL based concrete and compared to the identical mixtures with Type I/II cement. Results show that PLC concrete overwhelmingly outperformed traditional Type I/II concrete which would allow a 1:1 ratio substitution of PLC concrete. At an age of 28 days, nonfibrous high-performance PLC concrete achieved higher strength parameters than Type I/II concrete in compression (+12%), tension (+7%), modulus of elasticity (+18%), and flexure (+22%). It also had a higher surface resistivity (+9%) and a lower rapid chloride permeability (-28%) which indicates better performance against chlorides. In addition, all HPC Portland Limestone Cement mixtures outperformed the control mix in terms of restrained shrinkage with the hybrid fibrous mix performing the best.
