Slag Cement Association members report an 11 percent year-over-year increase in 2018 shipments, to 3.45 million metric tons. “Those of us in the concrete industry have long known that the use of slag cement increases the strength and durability of concrete at a reduced environmental impact,” notes SCA President Ed Griffith. Last year’s slag cement volume, up from 3.11 million mt in 2017, he adds, “represents the strength of our economy and increased understanding of the benefits of slag cement in the design, specification, and construction communities.”

Based on data from its recently released Precast Industry Benchmarking Report and leading forecasters, NPCA projects U.S. producers’ shipments increasing this year to $16.8 billion from $15.9 billion in 2013, the 6 percent gain modest against higher overall construction growth in 2014.

Two years after its launch across Canada, an industry-branded portland cement with up to 15 percent ground limestone content—promoted for reducing carbon dioxide emissions by 10 percent against conventionally milled powder—has gained significant traction among concrete producers and their customers.

After several years of stagnation, the precast concrete industry is turning the corner in recovery from the Great Recession, with NPCA’s 2013 Benchmarking Report indicating 2 percent higher volume in 2012 over the prior year—coupled with a near-doubling of profit margins, from 2.5 percent to 4.9 percent.

In a move that will provide the opportunity for the cement and concrete industries to reduce products’ carbon footprint, a proposal was approved to permit up to 15 percent ground limestone in blended cements under ASTM C595 (Blended Hydraulic Cements), with the resulting product characterized as limestone blended cements. Similar revisions are being made to the equivalent AASHTO standard by the AASHTO Subcommittee on Materials. Under C595, there was previously no specifically stated limit on ground limestone content.
