Ground Glass Pozzolans (GGPs) replace up to 50% of the cement in concrete. The cement component of concrete imparts a large Global Warming Potential (GWP) and replacing the cement with GGPs dramatically reduces concrete’s GWP. GGPs are made from recycled post-consumer bottle glass that would otherwise be landfilled. The glass is sourced regionally, GGPs are manufactured locally and distributed regionally – this constitutes the perfect circular economy. GGPs produce a stronger and more durable concrete with extreme resistance to chloride penetration (road salts), sulfate attack and freeze/thaw damage from water penetration.

Join us and Managing Partners, Patrick Grasso & Louis Grasso, Jr. on a tour of the Urban Mining Industries factory.

Tour A: 4-5pm

Tour B: 4:15-5:15pm

Learning Objectives

1. Develop an understanding of how pozzolans work in concrete. Specifically through the discussion of the history of pozzolans, the definition of a pozzolan from ASTM C 125, and the definition of a Ground Glass Pozzolan (GGP) from ASTM C 1866. The chemistry of how pozzolans work in concrete is describe.
2. Develop an understanding of the industry solutions created by the manufacture of GGPs and their use in concrete including; GGPs aren’t required to be color separated and glass particles much smaller than 3/8” can be utilized, hence very little glass gets landfilled. And, GGPs help fill the void left by the decline in production of fly ash and slag in the Pozzolan industry. Finally, GGPs dramatically reduces the GWP of concrete
3. Discuss the results of GGP use as cement replacement, through the following technical concrete performance metrics; Rapid Chloride Permeability Test (ASTM C1202), expansion due to sulfate attack (ASTM C1012), compressive strength (ASTM C39), Free Shrinkage (ASTM C 157), Freeze-Thaw Cycling Test of Durability (ASTM C 666) with experts from Urban Mining Industries, who were instrumental in creating and passing of ASTM C1866 Standard Specification for Ground-Glass Pozzolan for Use in Concrete. The technical requirements of this standard are discussed and compared to ASTM C618 the standard specification for fly ash used in concrete.
4. Discover hands-on examples of the use of GGPs in concrete products, including a multitude of projects where concrete block and pre-stressed plank are the primary structural components of the projects. The first ever cast-in-place use of GGPs was demonstrated by the Durst Organization for all the high-strength structural concrete in their Halletts Point project in Queens. 2.2 million square feet of 6000-PSI floor slabs were cast using GGPs in the JP Morgan Chase Global HQ project in Manhattan.
