CTS produces Rapid Set® Cement and Komponent® Type K shrinkage-compensating cement. Rapid Set® is a calcium sulfoaluminate (CSA) cement, an ASTM C1600-compliant alternative to portland cement made with 20% less limestone than portland cement, lowering CO2 emissions from calcination, and processed at lower kiln temperatures, lowering emissions from fuel consumption. Rapid Set® can achieve 4500 psi compressive strength in less than two hours and, unlike other CSAs, doesn’t require blending with portland cement or accelerating additives and admixtures. Komponent® is an ASTM C845-compliant shrinkage-compensating cement additive that is blended with portland cement or portland-limestone cement (PLC) to create Type K shrinkage-compensating concrete and grout. Made with our CSA cement technology, its global warming potential (GWP) is almost 56% lower than portland cement's. Contact CTS for the Type III EPDs for Rapid Set® Cement and Komponent® shrinkage-compensating cement additive.

Lyten is a supermaterials application company at the forefront of innovation with the creation of a new class of nanocarbons, known as 3D Graphene. By incorporating 3D Graphene into concrete, we achieve remarkable improvements in strength and durability and enable concrete with reduced emissions. Lyten’s proprietary processes permanently sequester carbon from methane in the form of 3D Graphene and utilize this tunable supermaterial platform to develop a myriad of decarbonizing applications. In addition to performance concrete admixtures, Lyten is commercializing high capacity lithium-sulfur batteries and next-generation infrastructure monitoring sensors. In 2024, Lyten was awarded Fast Company’s #8 Most Innovative Energy Company and named one of America’s Top Green Technology Companies by Time magazine. The company lists more than 420 patents granted or pending and is currently manufacturing Lyten 3D Graphene material and its applications in San Jose, California.

Ash Grove, a CRH Company, is a leader and pioneer in the cement industry. For over 140 years, we have provided cementitious materials to construct the highways, bridges, commercial and industrial complexes, homes, and other structures fundamental to the nation’s economic vitality and quality of life. In 2021, Ash Grove shipped 14.3 million tons of cement from 12 cement plants and its network of 43 terminals located throughout the Midwest, Texas, Florida, the Western United States, the U.S. Great Lakes and Canada. Ash Grove is fully aligned with the industry roadmap to attain carbon neutral by 2050, through low carbon cement and concrete, increased use of biomass and green fuels, decarbonated raw materials, clean and renewable energies.

CarbiCrete is a Montreal-based carbon removal technology company that is developing innovative, low-cost building solutions that contribute to the reduction of greenhouse gas emissions. The company’s patented technology, first developed at McGill University, enables the production of cement-free, carbon-negative concrete. The process uses an industrial by-product – the slag from steel factories – to replace cement as a binding ingredient in precast concrete products. The process injects CO2 into the fresh concrete to provide strength, while permanently sequestering CO2 within the resulting products. CarbiCrete’s licenses its technology to concrete makers and oversees the retrofit required to implement the process. The company’s corporate headquarters and R&D facility are located in Lachine, Quebec, and pilot project that will see production ramp up to 25,000 CMUs per day is currently underway at Patio Drummond, a hardscape manufacturer in Drummondville, Quebec.

At Ecocem, we’ve been committed to developing low carbon cement solutions for over 20 years and that commitment remains undimmed. CO2 changes everything. We are determined to accelerate our innovation and our progress and keen to work with industry and policymakers to deliver solutions.

Primekss is the world’s leading concrete technology company, creators of unique, patented steel fiber reinforced self-stressing concrete (SFRSSC) technology – PrīmX.

The Concrete Masonry & Hardscapes Association (CMHA) represents a unification of the Interlocking Concrete Pavement Institute (ICPI) and National Concrete Masonry Association (NCMA). CMHA is a trade association representing US and Canadian producers and suppliers in the concrete masonry and hardscape industry, as well as contractors of interlocking concrete pavement and segmental retaining walls. CMHA is the authority for segmental concrete products and systems, which are the best value and preferred choice for resilient pavement, structures, and living spaces. CMHA is dedicated to the advancement of these building systems through research, promotion, education, and the development of manufacturing guides, design codes and resources, testing standards, and construction practices. CMHA members are committed to producing concrete masonry units that contribute to resilient and sustainable communities.

Eco Material Technologies (Eco Material) is the leading provider of supplementary cementitious materials (SCMs) in North America. With over four decades of experience in marketing fly ash to the concrete industry, Eco Material is a pioneer in developing new construction material technologies. The company provides an environmentally friendly solution to conventional cementitious materials. Our products utilize resources that would otherwise be landfilled (e.g., fly ash), reducing the environmental impact of cement. Ready-mix concrete producers and contractors benefit from Eco Material’s reliable supply, technical expertise, sales, and service support. Additionally, Eco Material offers comprehensive on-site ash handling and management, and engineering services. Eco Material’s services extend to marketing fly ash and synthetic gypsum, significantly reducing the amount of coal combustion products (CCPs) that are landfilled. The company also harvests and beneficiates previously landfilled CCPs, enabling the clean reclamation of existing ash deposits. By supplying fly ash for concrete, synthetic gypsum for wallboard and agricultural uses, and various specialty products for construction materials, Eco Material optimizes the use of materials for their most effective applications.
