Concrete plays a vital part in construction industry. However, the production of concrete, notably cement, pose sustainability issues that need to be managed. To improve the sustainability of concrete, innovative admixtures, which contain Calcium Silicate Hydrate (C-S-H) nanoparticles, were developed at Master Builders Solutions. The patented admixtures can significantly enhance concrete strength at early and late ages. The use of this concrete admixtures enhances a reduction of considerable amounts of cementitious materials, typically in range from 50 lb/yd3 (30 kg/m3) to 100 lb/yd3 (60 kg/m3) to achieve similar strengths of those control concrete mixtures without the admixtures. In other hand, these innovative admixtures also enable a higher replacement of portland cement with supplementary materials such as fly ash, slag cement and milled limestone, reduction of heat-curing and/or curing time. The information presented will show how the use of the nanoparticle-based admixtures can provide options to modify, improve properties, increase the speeds of concrete curing and construction process, and reduce CO2-footprint of the concrete mixtures.

Join Mark Bury from Master Builders Solutions as he discusses projects that used a high replacement of portland cement, resulting in lower carbon emissions. The case studies include One World Trade Center, 432 Park Ave., San Francisco Public Utilities Commission Building, and The Reed.

R.D. Hooton, PhD, University of Toronto, talks about the path forward for concrete and how ASTM standards allow less clincker in cement, less cement in concrete, and less concrete in construction. The presentation talks about moving to performance specifications, and how to meet the 2030 goals for reduction in GWP, starting with using currently available levers to reduce C02 emissions.

Join Bob Nussmeier, Vice President of Strategic Clients at Baker Construction, as he explores how collective action can drive sustainability forward, ensuring a better future for our communities. In this presentation, he journeys through Baker's legacy from its humble beginnings in 1968 to becoming the nation's largest concrete contractor, driven by innovation and excellence. Nussmeier delves into the importance of sustainability in construction, highlighting our shared responsibility to reduce carbon emissions and adopt greener building practices.

Presented byTom Tietz of the California Nevada Cement Association. Since 2017 there have been a wide variety of concepts that have been proposed to reduce carbon emissions for California cement and concrete levels at state and local levels. These have included legislation, local measures, and building code proposals to limit embodied carbon. Some of these initiatives were being created by entities with little understanding of the complexities of cement and concrete production and value chain. This spurred the California Nevada Cement Association to produce a carbon neutrality plan released in 2021. The purpose of this plan is to proactively engage in removing the barriers to decarbonization and to provide a foundational reference for the pathway to carbon neutrality for cement consumed in California. One significant outcome is that this plan provided the framework for Senate Bill 596: Greenhouse gases: cement sector: net-zero emissions strategy. This presentation will highlight the components of CNCA’s carbon neutrality report, the direction of SB 596 (the first sector-specific net zero bill in California history) and other policy initiatives in various forms of current development.
