Development and Testing of Lime Based Mortars Using Perlite By - Products
Perlite is a volcanic rock containing high amount of amorphous material as well as alumino-silicate minerals. The outcoming product (expanded perlite) is often used in construction, due to its light weight and insulating properties. During its industrial process, an increasing number of by-products results that mainly remains unexploited as the fineness of these materials renders them difficult to store. In this study, an effort has been made to experimentally study the influence of two by-products (D1S, D1C), in lime-based mortars. These materials have been used as binders. To this direction, 9 mortar mixtures where manufactured and tested where natural pozzolan was gradually replaced by the perlite by-products. The Binder/Aggregate ratio in all mixtures was maintained at 1/2, whereas aggregates were natural of siliceous origin and gradation 0–4 mm. The physico-mechanical properties of the specimens were tested at the age of 28 and 90 days. From the correlation of the results, it was asserted that the partial or even total substitution of natural pozzolan by perlite by-products, enhanced the mortars’ physical and mechanical properties. It maybe therefore concluded that the exploitation of waste perlite in the construction sector is feasible, leading to the development of effective, low-cost and environmentally friendly products for specific applications.
