Abstract Warm asphalt mixture develops rapidly throughout the world in recent years. Zeolite based warm mix is one of the warm mixtures. In this paper, seven kinds of zeolites including six natural zeolites and one synthetic zeolite are selected. As warm mix additives, their physical properties such as density, water content and pore arrangements are tested respectively. To evaluate the compacting properties of zeolites based warm asphalt mixture, AC-20 mixture is designed and compaction is conducted. It shows that zeolites can reduce the compacting temperature for both Marshall and gyratory compaction. Temperature is the main factors which influence the compaction ... Διαβάστε περισσότερα

“Predicted” zeolites may fuel efficient processes | Zeolite.gr ​Scientists at Rice Univ. and the Univ. of Minnesota have identified synthetic materials that may purify ethanol more efficiently and greatly improve the separation of long-chain hydrocarbons in petroleum refining. The results show that predictive modeling of synthetic zeolites, a technique pioneered by Rice bioengineer Michael Deem, is highly effective and can help solve some of the most challenging problems facing industries that require efficient ways to separate or catalyze materials. Deem is co-author of a new study led by Univ. of Minnesota chemist Ilja Siepmann that appeared in Nature Communications. Zeolites ... Διαβάστε περισσότερα
