AERO Aggregates\u2019 foamed glass aggregate (FGA) was used to build the supporting structure that quickly stabilized the road in an emergency repair.<\/p><p>AERO Aggregates is a Pennsylvania-based company with a second plant in Florida and another planned in California.

Workers then add a proprietary, mineral-based foaming agent and heat the powder in a kiln at 1,650 degrees Fahrenheit.<\/p><p>The material emerges from the kiln looking like a long, gray sheet of cake. Upon cooling, the material cracks into gravel-like pieces.<\/p><p>She continued, \u201cWe aim for the bulk density of our standard product to not be any heavier than 15 pounds per cubic foot, which corresponds to about 240 kilograms per cubic meter. We follow the ASTM C29 standard for this type of bulk density measurement.\u201d<\/p><p>\u201cThe other test that we run on a daily basis is a confined compressive strength test, which is what we use our Tinius Olsen 150ST machines for in each of our Philadelphia and Florida plants, with one on order for California. The company\u2019s experience and input has been invaluable in developing our FGA product from the get-go and being a local company to ourselves has been an even bigger bonus.\u201d<\/p><p>\u201cThe test method used for these compressive tests is EN 1097-11 although we\u2019ve started down the road of trying to get a similar test standard in place at ASTM, which will obviously take some time.\u201d<\/p><p>\u00a0<\/p><h2>Supporting a Circular Economy<\/h2><p>But where does all the required glass come from?<\/p><p>\u201cMost communities do have some type of recycling program in place. The trend in recent years has been that some communities have dropped glass from the materials that they\u2019re collecting through single-stream programs, but certainly there\u2019s still many programs that do collect glass.\u201d<\/p><p>\u201cWe work with recycling entities that are local to our plants to source the glass product that we need. We generally take lower-value glass because it\u2019s the mixed color, the smaller pieces that generally can\u2019t be used by a bottling operation or even a fiberglass plant. The glass product that we use generally goes to a landfill if we don\u2019t take it.\u201d<\/p><p>\u201cwith the addition of our California plant, we\u2019ll have the capacity to divert over 500 million bottles per year from landfill.\u201d<\/p><p>It\u2019s been an amazing journey for Aero Aggregates and a perfect example of how materials testing is vital to the development of any exciting new product. This is especially true with FGA, which can make such a huge difference to everyday life and Tinius Olsen looks forward to helping develop this material even further in the future.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>How bottles and jars are changing the face of civil engineering projects and the testing needs behind it all.<\/p>\n<p>How many tons of recycled glass would it take to build an emergency support for one of the busiest four-lane highways in the world?
