Deterioration and Restoration of Plaster, Concrete and Mortar
This paper discusses plaster, concrete and mortar in terms of their chemical composition, reviews the deterioration of these materials and suggests possible conservation treatments for them. In terms of chemical components, plaster is considered in this paper as being formed primarily of calcium carbonate or calcium sulfate dihydrate (or a mixture of the two); concrete as primarily a mixture of...
متن کاملPerformance of date palm fibres reinforced plaster concrete
This paper describes an investigation on the use of a new composite construction material composed of plaster, sand, crushed gravel and date palm fibres of waste agriculture peels, having mechanical properties potentially useful in technical domains. Thermal conductivity and some mechanical and physical properties are investigated. The results showed that the incorporated vegetable fibres chang...
متن کاملMODELING THE COMPRESSIVE STRENGTH OF CONCRETE MADE WITH EXPANDED PERLITE POWDER
In recent years, soft computing and artificial intelligence techniques such as artificial neural network (ANN) and adaptive neuro-fuzzy inference system (ANFIS) have been effectively used in various civil engineering applications. This study aims to examine the potential of ANN and ANFIS for modeling the compressive strength of concrete containing expanded perlite powder (EPP). For doing this, ...

as a catalyst in chemical reactions an abrasive; and as an Electrokinetic properties of expanded and unexpanded perlite agent in mixtures for oil well cementing (1). samples have been investigated using the microelectrophoresis However, no studies about the surface interactions that technique. Perlite samples yield practically no isoelectric point in occur at the interface when perlite is incor...
متن کاملCompressive and splitting tensile strength of autoclaved aerated concrete (AAC) containing perlite aggregate and polypropylene fiber subjected to high temperatures
This paper presents the results of an experimental study on the residual compressive and splitting tensile strength of autoclaved aerated concrete (AAC) containing perlite and polypropylene (PP) fiber subjected to high temperatures. Cylinder specimens were subjected to various temperature ranges of 100, 200, 400, 800, and 1,000°C. The mixtures were prepared with AAC cementitious materials conta...
