Abstract:
The geology and mineralogy of the perlite from Kimolos island is examined in this paper. The perlite produced between 2.0 and 0.9 Ma ago during the last volcanic episode of Kumolos volcano in the Aegean sea. It is green in color and presents onion-skin structure under the microscope. The absence of large perlite fragments in the field is characteristic of Kimolos deposit compared with the perlite from the nearby island of Milos. The perlite mainly consists of glass (>85%), while the main mineral phases are plagioclase (with oligoclase-andesine composition), quartz, biotite, titaniferous mag

Abstract The research aimed to determine the ability of expanded perlite to adsorb or remove Cu (II) metal ions in the solution. Furthermore can be used to reduce Cu levels in the aquatic environment caused by industrial and mining waste. Expanded perlite is a product of perlite resulting from heating at temperatures above 1000°C. Perlite is a volcanic product contains high silica content and a lot of water content so when heating occurs will increase the porosity and surface area that can cause adsorption.

Perlite is a glassy volcanic rock that contains approximately 70-75% silica and 12-18% alumina. There are very large perlite reserves in the world (~6700 million tons) and approximately two thirds of these is in Turkey. Due to its high amounts of silica and alumina, at the beginning of such a study, it seemed that it would be worth first to find out whether perlite possesses sufficient pozzolanic property when it is a finely divided form and then to investigate whether it could be used as a pozzolanic addition in producing blended cements.

Abstract:
Abstract It is well known that moist fire protection materials show good fire resistance characteristics. For this reason, these materials are usually made of mixtures of cement mortar and high-water content materials such as silica gels or moist perlites. The latent heat of water plays an important role in the resistance of heat propagation in these materials. In this study, the thermal conductivity of mixtures of perlite-mortar and super-absorbent polymer gel to increase its water storage capacity, were measured. Also, the water content of the test materials was measured. Using the measured

Abstract:
Over the last decade there has been a dramatic shift in global agricultural practice. The increase in human population, especially in underdeveloped arid and semiarid regions of the world, poses unprecedented challenges to production of an adequate and economically feasible food supply to undernourished populations. Furthermore, the increased living standard in many industrial countries has created a strong demand for high-quality, out-of-season vegetables and fruits as well as for ornamentals such as cut and potted flowers and bedding plants. As a response to these imminent challenges and dem
