Sustainable concrete with granulate from asphalt scores well

Concrete with cleaned aggregate from demolished tar asphalt scores better for the environment than concrete with sand and gravel extracted from nature. They know that even at Zwaagstra Beton. The company is constantly developing new products, new methods and even new production halls. "We are experiencing enormous growth, even at the quality level," says André Veerkamp, field sales manager at Zwaagstra Beton.

"We have just completed an entire process to ensure that we meet the strict requirements of the KIWA with all of our concrete slabs." In addition, Zwaagstra Beton received the silver CSC certificate in early March. "You don't just get a certificate like that, of course. I am very proud of our team for completing this process with a positive result." But Zwaagstra wouldn't be Zwaagstra if they weren't already busy realizing new plans....

ECO granulate

"When making choices for our business, we certainly also choose sustainable production," Veerkamp continued. "Because primary raw materials, such as gravel, are becoming scarcer and the European standard for concrete composition allows for a replacement rate of 30% for many applications, we started looking at the possibilities. The use of aggregate is an important factor here in relation to the circular economy. Granulate, from demolished tar asphalt, is thermally cleaned by Recycling Kombinatie REKO and they supply this secondary certified aggregate under the name ECO granulate. The granulate has the same properties as primary gravel, in terms of quality and constructability."

Komo certified

"Our lab technician and concrete technologist are constantly working on quality. Measuring, calculating, improving recipes. We make trial slabs, we test and only when it meets our high standards and it is cost-effective do we apply it in our products." Veerkamp concludes, "Not for nothing are the ECO granulate and all our concrete slabs KOMO certified!"
