The recycled aggregate permeable concrete made of reused construction wastes is very important for realizing the sustainable development industry, it can alleviate adverse impact surface runoff during storm and urban heat island effect. Therefore, this paper studied mechanical properties durability concrete. At first, a few target material, including bulk density, moisture content, water absorp...

this paper is based on an experimental research that examined the effects of concrete`s major parameters on durability of concrete pavements and curbs under freezing and thawing cycles. these parameters include concrete mix design parameters such as water-cement ratio, fine aggregate percentage and using air entraining admixture and simulating real freeze-thaw cycles that infrastructures underg...

Unlike natural aggregate particles, recycled concrete aggregates contain hardened cement paste phases and multiple interfacial transition zones. These differences in properties may be linked to a decrease durability performance concrete. This paper presents review of the literature published on produced using untreated fine (fRCA). From available literature, made fRCA is strongly w/b used poros...

This paper reports the results of tests on Indiana gravels ranging from good to poor in field performance in Portland cement concrete. The gravels were separated by heavy liquid flotation into various specific gravity ranges. The gravel fractions thus obtained were tested to deter­ mine absorption, specific gravity, degree of saturation, lithologic compo­ sition and durability in air entrained ...
