Abstract:
Roman Cement uses a patented technology that permits a re-design of a standard concrete mix — driving concrete performance up, and material cost down…all while making concrete better for the world’s economy and environment. The patented technology improves cement hydration efficiency, reduces excess capillary water, and increases particle packing density of the entire system (aggregates and cement paste) throughout the structure of the concrete product. The City of Salt Lake used the patented Roman Cement technology to re-design their standard concrete mix to be used for their Electric Bus Charging Station project. The Roman Cement re-design enabled the City of Salt Lake to reduce the use of cement (and therefore the carbon footprint and overall material cost) as compared to their standard and historical mix design. The redesign also improved strength, workability, performance, and durability of the concrete. The Project was completed in 2022 and still looks beautiful today without any cracking, spalling or other observable defect, unlike some of the portions where the original standard mix was used.
