In response to the high water sorptivity of alkali-activated slag–red mud–steel slag cementitious material (AASRSS), and aggressive ions are easily transferred interior materials, which poses a significant threat their durability. order limit transfer moisture AASRSS, sodium stearate (NaSt) was utilized in this paper reduce its sorptivity. The aim study elucidate role NaSt AASRSS system. change...

Abstract The permeable pavement is a compensatory drainage technique for urban waters that aims to control runoff and ensure ideal hydrological conditions. This work had as main objectives evaluate the infiltration capacity of (PP) at real scale, through analytical numerical modeling. It relies on water experiments related modeling hydrodynamic characterization coating layer (saturated hydrauli...

hydraulic attributes play important role in hydrological studies, soil conservation, designing irrigation and drainage systems, soil conservation, and controlling soil erosion in watersheds. their measurements are very tedious and time consuming and due to high spatial variability, a large number of measurements are required for obtaining reliable values. nowadays, prediction of these attribute...

7 The effects of entrained air on microstructure and transport properties of concrete with up to 11.5% air at different w/c 8 ratios, curing and conditioning regimes were investigated. It was found that air voids disrupt the packing of cement and 9 increase the heterogeneity of the microstructure. The width of the affected interface is around 30 μm. Gaseous 10 diffusivity and permeability are i...

This paper aims at the experimental study of durability properties and long-term mechanical self-compacting concrete with fly ash as secondary cementitious material copper slag inert material. Cement replaced 20% level fine aggregate 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%. Twelve different mixes were prepared to assess like RCPT, Sorptivity, UPV. The microstructure SCC was observed u...
