Researchers’ concrete findings on glass

Researchers at Deakin University’s School of Engineering have developed a new type of concrete made from ground recycled glass.

Traditionally, sand is used for making polymer concrete, a material often used in industrial flooring. But researchers have found that the addition of glass resulted in a stronger product that is less costly to produce.

"This research provides the evidence the construction industry needs to see the potential of glass as a substitute for sand when making polymer concrete and, potentially, concrete," Dr Riyadh Al-Ameri, the senior engineering lecturer at Deakin’s Faculty of Science, Engineering and Built Environment, said.

"Concrete is a major construction material and sand is one of its primary components, so finding an alternative to sand makes good economic sense.

"Mined sand requires washing and grading before it is added to aggregate, cement and water to make concrete. We have found that substituting sand with ground recycled glass makes the polymer concrete stronger and is a sustainable use of one of the major types of recyclables in the domestic waste stream.

"Any changes that reduce the cost of production will lead to significant gains across the industry, potentially on a global scale," Dr Al-Ameri said.

From concept to market

Polymer concrete uses polymers, typically resins, to replace lime-type cements as a binder. It is a high strength, water-resistant material suited to industrial flooring and infrastructure drainage, particularly in areas subject to heavy traffic such as service stations, forklift operating areas and airports.

Deakin Engineering student Dikshit Modgil worked with Melbourne-based Orca Civil Products as part of his Master’s research into the suitability of recyclable glass in polymer concrete production.

Orca Civil Products director Alan Travers said the research partnership had produced results that would be useful in taking the concept further to commercialisation.

"The specific type of waste glass used in this project was unsuitable for recycling back into glass and the amount that is stockpiling is becoming a community problem," Travers said. "The concept has even more appeal to us because of predicted shortages of natural, mined sands in the medium term."

Dr Al-Ameri said the next stage of Deakin's research would look at substitutes for the aggregate in polymer concrete, optimising the substitution rate, assessing durability, and the commercialisation of the new product.
