Recent Reports from the Hardscape Industry
The American Concrete Institute recently released a new guide covering the shotcrete process. Included in the new publication ACI 506R-16 Guide to Shotcrete is information on materials and properties of both dry-mix and wet-mix shotcrete, equipment requirements and selection, composition, qualifications and responsibilities of shotcrete crews, formwork, application procedures, pre-construction trials, types of finishes, craftsman qualification tests, materials tests, and finished shotcrete acceptance tests. https://www.concrete.org/publications.aspx
Another new type of cement can be manufactured at less cost with lower greenhouse gas emissions, and produce a more durable concrete according to engineers from Oregon State University, Purdue University and Solidia Technologies, which licensed core technology from Rutgers University. Called carbonated calcium silicate-based cement or CCSC, its early uses are predicted to be for precast concrete products.
"With Build with Strength we have an opportunity to re-energize the concrete industry and better position concrete products in the construction marketplace... reminding people inside and outside of the industry that no product is as safe, strong or durable as ready mixed concrete."
