摘要:Abstract(#br)The shrinkage and durability properties of a total of 34 concrete mixes with recycled aggregates produced from different untreated construction and demolition waste (CDW) were tested. The effect of a polycarboxylic superplasticizer on the enhancement of these propert...

摘要:Abstract(#br)High water absorption is the main drawback of recycled aggregates which greatly hinders the re-use of them in concrete production. In this study, bio-deposition treatment, based on bacterially induced CaCO 3 precipitation, was applied to improve the quality of the recycled aggregates...

摘要:Abstract(#br)The use of recycled concrete aggregates is very attractive from the point of view of reducing concrete production costs and of sustainability. A peculiar origin of such aggregates is that of demolitions of pre-existing concrete buildings.(#br)Scope of this work is to...

摘要:... To this end, this study uses fractal theory, image processing, and scanning electron microscopy (SEM) to analyze the spatial stratified heterogeneity (SSH) of recycled aggregates and the mechanical properties of the CPB under the natural flow of slurry. The spatial distrib...

摘要:Abstract(#br)This paper intends to evaluate the real influence of a commercial densified silica fume (SF) and of recycled concrete aggregates (RA) on the behaviour of high-performance concrete (HPC). For that purpose, three families of concrete with 0%, 5% and 10% silica fume...
