Abstract Concrete is one of the materials most used by the construction industry. Reinforcing this material with fibers is a technique used to improve its mechanical properties. Steel and polymer fibers are the main types used in this application and there are few studies about the influence of polymer fibers on the thermal properties of concrete. In order to analyze this influence, the present work carried out thermal conductivity, thermal expansion, and compressive strength after exposure to a temperature of 200 °C on specimens made of concrete with addition of polypropylene (PP) fibers and concrete with addition of high modulus polyethylene (HMPE). It was also conducted thermogravimetric analysis (TGA) on PP and HMPE fibers. The results show that the addition of polymer fibers alters the thermal properties of the concrete, reducing its thermal expansion, for example.

The status of denture-base poly(methylmethacrylate) (PMMA) has been reviewed, and in spite of the availability of mechanically superior injection-molded resins, it remains the material of choice. PMMA can be reinforced with fibers, the most recent being ultra-high-modulus polyethylene fibers. Various elastomer reinforced materials are also available. Alternatives to room-temperature polymerizing PMMA resins include higher methacrylates and epimine resins. High-modulus resins have been produced with Bisphenol A-glycidyl methacrylate (BisGMA) and tetrahydrofurfuryl methacrylate, involving an anti-plasticizer function. Also reviewed are room-temperature polymerizing initiators, radio-opaque resins, and studies on polymerization shrinkage.
