Zeolite in Construction

A new exploration licence has been granted by the Decentralised Administration of Kavala for Greek zeolite in the Mavri Petra area, near Petrota in Northern Evros. Thus, the Thessaloniki-based company Olympus is continuing its research efforts, whilst at the same time awaiting the final permits to proceed to the general mining licence in the Kokkalo area, which is, of course, also located near Petrota. In practical terms, this means that work is being carried out in parallel to save time and lay the groundwork for the future, ensuring continuity with other deposits. This also highlights the significance of the whole ... Read more

Rather than waiting for everything to come to us, we must take steps towards innovation ourselves. With the first samples demonstrating the quality of Greek zeolite in the Kokkalo area, we have the opportunity to develop new products that offer added value. Greek zeolite is clinoptilolite, but each has its own local characteristics. Greek zeolite is of the Eulandite type. It therefore has a general formula: (Ca,Na₂)₂(Si₇Al₂O₁₈), 6H₂O, but as it is clinoptilolite, it contains the following elements: Si-Al-Na-K-Ca. However, as we are actually talking about zeolite tuff, there are always other elements present. Read the rest here: Lygeros.org

It is now time to move on to the next stage, to stop focusing exclusively on the economy and to invest in strategic thinking. Enough already of this Greek-style culture of misery, where the whole point is how to undermine one another in order to win votes. We are part of Hellenism and must rise above these wretched party differences and disputes. We must devote all our energies to helping both Greece and Cyprus. If we do not have a strategic goal on which we all agree, then we deserve our fate. Read the rest here: Lygeros.org

Babak Ahmadi *, Mohammad Shekarchi Construction Materials Institute, Department of Civil Engineering, College of Engineering, University of Tehran, Tehran, Iran abstract Natural zeolite, a type of frame-structured hydrated aluminosilicate mineral, is used abundantly as a type of natural pozzolanic material in some regions of the world. In this work, the effectiveness of a locally quarried zeolite in enhancing mechanical and durability properties of concrete is evaluated and is also compared with other pozzolanic admixtures. The experimental tests included three parts: In the first part, the pozzolanic reactivity of natural zeolite and silica fume were examined by a thermogravimetric method. In ... Read more

Abstract Warm asphalt mixtures have seen rapid development worldwide in recent years. Zeolite-based warm mix is one such type of warm mixture. In this paper, seven types of zeolites – comprising six natural zeolites and one synthetic zeolite – were selected. As additives for warm mix, their physical properties, such as density, water content and pore arrangements, were tested individually. To evaluate the compaction properties of zeolite-based warm asphalt mixtures, an AC-20 mixture was formulated and compaction tests were carried out. The results show that zeolites can reduce the compaction temperature for both Marshall and gyratory compaction. Temperature is the ... Read more
