After eight years as Massachusetts Institute of Technology Concrete Sustainability Hub executive director, Jeremy Gregory has transferred to a position with the newly formed MIT Climate and Sustainability Consortium. MIT officials credit his spearheading of impactful research, encouraging connections between lab members, fostering industry partnerships, and greatly expanding the CSHub’s reach and presence nationally and internationally.
“His insight, clarity, and optimism benefit any organization that he is a part of,” says CSHub Co-Director Randolph Kirchain. “Over the last decade, he has shaped CSHub’s research so that today it delivers not only innovation but also real impact.” Impacts have been far reaching, he adds, as Gregory’s work at CSHub has culminated in more than two dozen peer-reviewed publications, which in turn garnered coverage in national news outlets on the order of Scientific American and Wired.
“Jeremy’s impact on the MIT CSHub cannot be overstated,” affirms Julie Garbini, executive director of the RMC Research & Education Foundation, which has underwritten CSHub activities with the Portland Cement Association. “He has been able to bring together industry leaders and a diverse group of researchers to prioritize and implement a multi-layered approach to concrete and cement sustainability—and then communicate that agenda and results to owners, designers, manufacturers, policymakers, and the general public.”
“Jeremy’s vision connecting the lab bench with industry practice defined a new paradigm of research at MIT and beyond,” notes CSHub Faculty Director Franz-Josef Ulm. “It will continue to reverberate throughout our research and implementation efforts in the CSHub for many years.”

Habitat for Humanity Saint Louis recently broke ground on a new home build, bringing together a collaborative team led by Concrete Strategies, part of St. Louis-based Clayco Enterprises and its affiliated workforce diversity nonprofit Construction Career Development Initiative (CCDI). Clayco founded CCDI as a 501(c)(3) in 2015 in response to the unrest in Ferguson, Mo. to provide career development opportunities to young minority adults who are underrepresented within the construction industry. The organization works to bridge the workforce diversity gap by partnering with various school districts in North St. Louis County and St. Louis City, community leaders, plus organizations such as St. Louis Job Corps and North Technical High School to cultivate a renewed interest in apprenticeships or career technical education programs.
Twelve skilled Clayco team members and CCDI volunteers took place in the build, which involved pouring foundations for two homes in the St. Louis Gate District. While Concrete Strategies and CCDI are providing volunteers and donations, the project is also fueled by a partnership with the St. Louis Job Corps Center’s construction program, Geotechnology, Inc., and other local subcontractors who partner with CCDI to hire program graduates into full-time employment. Three CCDI graduates who are now employed full-time with Concrete Strategies are participating in the build.
“Habitat for Humanity appreciates the tremendous planning, skills and time that each of the partners in this build have dedicated,” says Habitat for Humanity St. Louis CEO Kimberly McKinney. “It’s especially meaningful knowing we are bringing together a changemaking group of individuals to participate. Our team of community partners are driving equitable opportunities for the underserved in our community.”
“This build signifies our shared commitment to placing underserved young people into full-time employment. Expanding our joint reach to ensure as many people as possible have access to career development in the construction field is critically important,” says CCDI President and Clayco Corporate Business Unit Executive Vice President Tom Sieckhaus.

The International Concrete Repair Institute has effected a new licensing agreement with Technical Applications for Concrete Materials, granting rights to the usage of the industry standard trademarked ICRI Concrete Surface Profiles, CSP. Referencing ICRI Guideline 310.2R-2013, TACM has developed a process for concrete samples that are comparative to ICRI’s “rubber chips.”
The ICRI CSP chips were introduced to the repair industry in 1997. They have gained world-wide adoption for being the method of concrete surface profile identification and remain the industry standard when referring to concrete surface profiles. Guideline 310.2R-2013 defines the CSP numbers ranging from 1 (nearly flat) through 10 (very rough; amplitude greater than 1/4 in.). The TACM concrete samples are mechanically or chemically processed by an actual method used to obtain the ICRI CSP profiles on a construction jobsite. While these profiles can be achieved utilizing various methods, the TACM samples will be produced specifically using the following methods: CSP 1 Acid Etched, CSP 2 Ground, CSP 3 Light Shotblast, CSP 4 Light Scarification, CSP 5 Medium Shotblast, CSP 6 Medium Scarification, CSP 7 Heavy Shotblast, CSP 8 Surface Retarder, CSP 9 Heavy Scarification, and CSP 10 Breaker/Abrasive Blast.
The TACM CSP samples will be available in sets of 10 different profiles, and boxes of one profile containing 12. As no two concrete surfaces are created the same, the new TACM concrete samples will depict a range of prepared surface profiles that could be produced on a jobsite as a complement to ICRI’s CSP rubber chips. Release of the new product is anticipated for Summer 2021. ICRI Guideline 310.2R-2013 and rubber chips are available at www.icri.org.
