Faserarmierter Porenbeton sowie Verfahren zu seiner Herstellung

摘要

Hydrothermally-hardened fiber-reinforced porous concrete product consists of a building material matrix made of solid stays surrounding spherical pores. The product has a micro-reinforcement in the form of short plant fibers. The plant fibers are in flax fibers embedded in the solid stay material and do not protrude into the pore chambers of the pores. An Independent claim is also included for a process for the production of the a hydrothermally hardened fiber reinforced porous concrete product comprising adding open flax fibers to a usual porous concrete mixture containing quartz sand and/or ground quartz, a binder such as chalk and/or cement, optionally gypsum and an expanding agent, e.g. aluminum powder, and water to form the micro-reinforcement.
