Polymer-Cement Composites Containing Waste Perlite Powder
نویسنده
چکیده
Polymer-cement composites (PCCs) are materials in which the polymer and mineral binder create an interpenetrating network and co-operate, significantly improving the performance of the material. On the other hand, the need for the utilization of waste materials is a demand of sustainable construction. Various mineral powders, such as fly ash or blast-furnace slag, are successfully used for the production of cement and concrete. This paper deals with the use of perlite powder, which is a burdensome waste from the process of thermal expansion of the raw perlite, as a component of PCCs. The results of the testing of the mechanical properties of the composite and some microscopic observations are presented, indicating that there is a possibility to rationally and efficiently utilize waste perlite powder as a component of the PCC. This would lead to creating a new type of building material that successfully meets the requirements of sustainable construction.

Statement of Purpose: Calcium phosphate cements are prepared by mixing calcium phosphate powder with a liquid component to form a paste that hardens over time via a dissolution-precipitation reaction. Thus, in addition to being osteoconductive and resorbable, these biomaterials have the advantageous property of being injectable. This property can be leveraged for castingbased approaches to scaf...

This study investigated the use of waste chicken feather (barbs and rachis) as reinforcement in cement-bonded composites. A series of composite boards consisting of various proportions of waste feather, cement, sand, and chemical admixtures were prepared. Mix workability decreased significantly as the proportion by weight of feathers or ground feathers increased from 5% to 20%. Boards containin...

On the Study of Mechanical Properties of Aluminum/Nano-Alumina Composites Produced via Powder Injection Molding
Powder Injection Molding (PIM) is a precision manufacturing process used for production of advanced composites. Mixing of polymeric binder with metal powders, molding of feedstock, de-binding of brown parts and sintering of green samples are four main steps of this process. In the present study, the compounds containing multi-component binder system and aluminum/ nano-alumina (0-9 wt.%) powders...
