Pore structure features of pervious concretes proportioned for desired porosities and their performance prediction

Influence of burning temperature and cooling methods on strength of high carbon ferrochrome slag lightweight aggregate

“…In this paper, the method of image analysis which was widely used in the pore structure characterization of foam concrete or pervious concretes was taken for references [19]. For image analysis, 50 Â 50 Â 30 mm cubic specimens were prepared and polished to obtain a smooth surface with pores exposed.…”

Effect of aggregate coating thickness on pore structure features and properties of porous ecological concrete

“…In this document, the porosity satisfying the plant growth should be between 18 and 30% (Advanced Construction Technology Center, 2001). The pore structure features and porosity play significant roles in the functional and structural performance of pervious concrete Neithalath, 2010, 2011;Sumanasooriya and Neithalath, 2011). Meanwhile, image analysis has been carried out on two-dimensional images of pervious mixtures to extract the pore structure features (Neithalath et al, 2010).…”

Investigation of internal curing effects on microstructure and permeability of interface transition zones in cement mortar with SEM imaging, transport simulation and hydration modeling techniques

“…Two standard methods were recommended by American Petroleum Institute and Army Corps of Engineers, respectively to directly measure the permeability [32,33]. Indirect methods including the rapid chloride permeability test [34] and the electrical impedance measurement [35][36][37][38] were also utilized successfully. In the meantime, researchers attempted to use 3D numerical simulation methods to calculate permeability based on SEM images.…”
