Data behind a new National Ready Mixed Concrete Association life cycle assessment report for cast-in-place concrete shows how ready mixed producers, through more efficient use of portland cement, have cut the respective carbon footprints of 4,000- and 8,000-psi orders by 13 percent and 20 percent since 2014. Armed with results from a survey of 155 member producers operating 1,954 ready mixed plants, the association analyzed data on material throughput and other metrics reflecting net energy consumption in slabs or structures.Read More

In an overview for ready mixed producers on the reorganized ACI-318, Building Code Requirements for Structural Concrete, NRMCA Senior Vice President, Engineering Colin Lobo notes how the just-released version: consolidates concrete mixture-specific references from 318-11 Chapters 3 (Materials), 4 (Durability) and 5 (Strength and Construction Issues) into new Chapters 19 (Concrete: Design and Durability Requirements) and 26 (Construction Documents and Inspection). The reorganization of these sections permitted an evaluation and elimination of some Code provisions related to concrete mixtures and construction when better addressed in other referenced standards.Read More
