An experimental investigation was carried out to study the effects of various percentages of fine/coarse tire waste and microsilica
at various temperatures on the compressive strength of concrete. The compressive strength of concrete mixtures made with tire
rubber was assessed statistically with those of concrete containing microsilica and conventional concretes in order to evaluate
the usefulness of recycling rubber waste as a component of concrete. Results confirmed that the recipe and processing temperature
of concrete cubes influence the compressive strength values. Generally, the use of microsilica or fine rubber mixed with microsilica
as aggregate replacement of 5% by volume improved the compressive strength of concrete processed at a temperature of 150°C.
The addition of coarse rubber did not achieve any increase in strength when used as an aggregate replacement at any percentage.
Moreover, the reductions in the compressive strength of concrete mixes at higher temperatures were much smaller for the fine
rubber with 5 vol% microsilica than those for control and coarse rubber mixes. The specimens made with fine rubber and 5 vol%
microsilica at elevated temperatures above 400°C appeared to show very similar compressive strength values. The use of fine
rubber in building construction could help save energy and reduce costs and solve the solid waste disposal problem posed by
this type of waste. 相似文献

Bow tie diagrams have become a popular method for risk analysis and safety management. This tool describes the whole scenario of a given risk graphically, and proposes preventive and protective barriers to reduce, respectively, its occurrence and its severity. The weakness of bow tie diagrams is that they are restricted to a graphical representation of different scenarios exclusively designed by experts that ignore the dynamic aspect of real systems. Thus, constructing bow tie diagrams in an automatic and dynamic way remains a real challenge. This paper proposes a new Bayesian approach to construct bow tie diagrams from real data and improve them by adding a new numerical that enables us to implement the appropriate preventive and protective barriers in a dynamic manner. 相似文献

Conventional methods to clean wastewater actually lead to incomplete treatments, calling for advanced technologies to degrade recalcitrant pollutants. Herein we review solar photo-oxidation to degrade the recalcitrant contaminants in industrial wastewater, with focus on photocatalysts, reactor design and the photo-Fenton process. We discuss limitations due to low visible-light absorption, catalyst collection and reusability, and production of toxic by-products. Photodegradation of refractory organics by solar light is controlled by pH, photocatalyst composition and bandgap, pollutant properties and concentration, irradiation type and intensity, catalyst loading, and the water matrix.
