A huge volume of waste is generated by natural and human-made disasters rapid urbanization that leads to the demolition structures reaching end their service life. Using recycled aggregates in concrete producing reduces environmental pollution decreasing disposal this material landfills preserving unreasonable exploitation resources. This manuscript presents results an experimental program aimi...

This paper first points out that the reducts obtained from a simplified decision table are different from those obtained from its original version, and from a simplified decision table, we cannot obtain the reducts in the sense of entropies. To solve these problems, we propose the compacted decision table that can preserve all the information coming from its original version. We theoretically d...

Roller compacted concrete (RCC) is a relatively new alternative construction material that can be used in road and dam constructions by allowing rapid use after production the of conventional building materials production. RCC, which produced with low water/cement ratio, one rigid pavement types shows similarity to flexible pavements technique. Different fibers such as steel polypropylene (PP) ...

Introduction. The shear strength of concrete, while not being an independently standardized indicator concrete quality, plays important role in the analysis reinforced structures. concepts related to dependence on compressive and axial tensile are quite ambiguous. Self-compacting (SCC), which has been widely used recently, is somewhat different from ordinary (OC) compacted by vibration terms st...
