The Cement Research Library (DVD025) is a searchable compendium of over 1,700 PCA cement-related research reports dating from 1916 to 2004. From the landmark studies of R. H. Bogue and T. C. Powers to very recent environmentally-related studies on cement, this vast collection represents significant cement-related research that laid the foundation for much of …
The lack of funding for R&D in cement and concrete, 136 and the lack of focus on industrial materials in the academic and research space more broadly, may partially explain this incremental approach to innovation. 137 Material scientists do not tend to work on concrete and instead focus on 'sexier' materials such as graphene. 138 The ...

Research and Development Since its inception in 2009, U.S. Concrete's National Laboratory has developed high performance concrete mixes using supplementary cementitious materials. These new mixes not only outperform traditional concrete mixes relative to set times and early strength, but significantly reduce the products carbon footprint.
In actual practice, the merging of ZnO in cement is suitable for the up-gradation of mechanical properties of cement and also aids in attaining sustainable development. The …

In September 2020, the Global Cement and Concrete Association – comprised of 40 member companies representing ~40% of global cement production – announced its commitment to deliver carbon-neutral concrete production by 2050. This makes cement the first industry subsector to have a global association set a net zero commitment.
