Adverse Environmental Conditions

Fibre Reinforced Plastics (FRPs) generally have greater advantages over conventional materials for their structural properties. However, the service life can significantly be shortened if the fibre reinforced plastics are exposed to adverse environmental conditions especially acid vapour, humidity and high temperature. In many chemical industrial plants in Australia and elsewhere fibre reinforced plastic gratings are used as structural components of stairs and passages where they are subjected to varying degrees of fluosilicic acid, a byproduct of the industrial manufacturing process. As currently no experimental data on the effects of fluosilicic acid on FRPs is available in the public domain, it is difficult to predict the service life of FRPs with some certainty. In order to understand the structural strength of fluosilicic acid exposed FRPs, an experimental study was undertaken. A series of specimens from various locations of a chemical plan in Australia were acquired and studied. Some new specimens (not exposed to acid, humidity and high temperature) were also studied to provide a benchmark for the comparison. The results indicated that the long time exposure to harsh environment and acid vapour can significantly deteriorate the flexural strength and service life of FRPs.

In this article discusses the mechanical properties of foam concrete, which submitted based on the experimental data of long force resistance and deformation of compression elements from foam concrete. Also submitted criterion range of strength and deformation characteristics of foam concrete different structural modification with taking into account the permanently acting load, which necessary for calculation and design structures of buildings. In article such characteristics of foam concrete as durability and deformability at the age of 28 days by results of short-term tests and also influence of average density and a type of structure on its durability and deformability are considered. Change of mechanical properties of foam concrete in time by results of short-term tests is analyzed and studied. Experimental and theoretical researches which have in turn allowed to recommend for rationing of value of settlement characteristics the foam of concrete taking into account their variability, aging and duration of action of loading are executed.
