- W197933358 abstract "Portland cement pervious concrete (PCPC) mixtures contain 15 to 35% voids, 15 to 30% paste and 50 to 65% of aggregate, by volume. The voids in the PCPC mixture are provided from the voids in the aggregate matrix. Designing pervious concrete with certain volumetric compositions (void, paste and aggregate contents) requires selection of aggregate with a particular void content. However, obtaining an aggregate with desired void content directly from single source cannot always be possible. Therefore, it may be necessary to blend different sizes to obtain an aggregate blend with specific void content. Blending aggregate with manual trial-and-error methods can be a time consuming and an expensive procedure. This study shows how PCPC aggregate properties such as; unit-weight, void content, surface area, and pore-diameter can be optimized for desired properties using simplex centroid design. It also shows the application of response surfaces analysis to select aggregate components that yield optimized multiple properties." @default.
