Waste palm oil products can be recycled in the production of pervious geopolymer concrete (PGC) for long-term sustainable development. PGC is a non-slip porous pavement that allows water to pass through. Biomass aggregate (BA) produced by burning biomass and introduced as replacement natural (NA). BA mixed with fly ash (FA) alkaline liquid (AL) heated an oven at 80 °C 24 h produce coated (CBA)....

The need for drinking water with affordable access is increasing nowadays. poor quality problems can be solved by several treatment methods, i.e. ceramic filter (CF) and pervious concrete (PCF). Those two mentioned technologies work based on the pores that exist within filter. This study aimed to review (1) influence of material composition CF PCF hydraulic characteristics (porosity, permeabili...

This work presents a proof-of-concept study of recycling low-quality urban-fringe construction and demolition waste for the development sustainable cement-free pervious concrete. Waste was in-situ collected from local site in Hangzhou, China, elaborately analyzed quality assessment. Ground brick powder activated by alkali activators at different (Al+Si)/Na ratios to find optimal mix ratio. Macr...

To optimize the pore skeleton structure of pervious concrete to enhance its phosphorus (P) removal from stormwater, small-sized adsorptive aggregate (1–2 mm steel slag) and large-sized natural (2–5 basalt), are applied for manufacture two-sized concrete. Physico-mechanical properties, adsorption performance freeze–thaw resistance investigated. The results show that slag fills pores between aggr...

In this paper, we consider wireless data broadcasting as a way of disseminating information to a massive number of clients equipped with battery powered palmtops. Using indexing technique, the clients can selectively tune in at desirable portion of the broadcast and conserve the usage of energy. We review the pervious works for indexing on nonuniform data broadcast in this paper and propose an ...

This research aimed at ascertaining the performance of raw dura species Palm Kernel Shells (PKS) in comparison to a different PKS (tenera) as replacement for known aggregates pervious lightweight concrete. Using limestones aggregates, control concrete was batched, and relevant tests were conducted. Major conducted on composites concerned compressive, tensile, flexural strength, well permeabilit...
