Recycled Polymer Materials as Aggregates for Concrete and Blocks
The potential of recycled waste polymeric materials as a substitute for aggregates in concrete has been investigated in the study. Two different types of waste polymer, namely polyurethane formaldehyde (PUF) based packaging waste and high density polyethylene (HDPE) were recycled and used in the experiment. Concrete and masonry poly block specimens were prepared using recycled polymer materials...
متن کاملUse of Polymer Concrete in Construction
Polymer concrete (PC) is a composite material in which the binder consists entirely of a synthetic organic polymer. It is variously known as synthetic resin concrete, plastic resin concrete or simply resin concrete. Because the use of a polymer instead of Portland cement represents a substantial increase in cost, polymers should be used only in applications in which the higher cost can be justi...
متن کاملRock Masses as Construction Materials
A rock mass is a material quite different from other structural materials used in civil engineering. It is heterogeneous and quite often discontinuous, but is one of the materials in the earth's crust, which is most used in man's construction. Ideally, a rock mass is composed of a system of rock blocks and fragments separated by discontinuities forming a material in which all elements behave in...
متن کاملEnvironmental-friendly durable concrete made with recycled materials for sustainable concrete construction
Concrete is one of the most widely used construction materials in the world. However, the production of portland cement, an essential constituent of concrete, leads to the release of significant amount of CO2, a greenhouse gas; one ton of portland cement clinker production is said to creates approximately one ton of CO2 and other greenhouse gases (GHGs). Environmental issues are playing an impo...
متن کاملPolymer-Silver Nanocomposites as Antibacterial materials
The antibacterial effect of silver has been used in a variety of commercially available products and medical devices for many years, either in its metallic or salt form. Nowadays, due to the knowledge acquired within the last decade in the field of Nanoscience and Nanotechnology, the use of silver nanoparticles (AgNPs) for medical and sanitary purposes has been thoroughly studied and dramatical...
