An Experimental Study of Clogging Recovery Measures for Ceramic Permeable Bricks

Abstract

To explore the best clogging restoration measures for ceramic permeable bricks, ceramic permeable bricks were accurately clogged using a self-designed device by controlling the permeability, and different technical measures were adopted to restore the permeability. Then, the recovery effect, operating parameters and pore change inside the bricks using pressure washing were further discussed. The results showed that pressure washing was the best recovery measure, the joint methods was not recommended due to performance to price ratio. It was necessary to conduct pressure washing in relatively moist conditions, increase the cleaning frequency or prolong the cleaning time in the case of no serious blockage. Hydraulic cleaning can not only increase isolated pores but also remove the trapped solid particles, and increase the proportion of connected pores and dredges through water channels. This research offers some reference for the daily maintenance of permeable bricks.

“…Papers [ 9 , 10 ] are focused on the production of ceramics with enhanced performance characteristics while paper [ 11 ] deals with the maintenance of ceramic porous bricks. The first two studies explore the possibility of using waste materials as modifiers of the traditional formulas of specific manufactured, with the purpose of reducing the firing temperature and, consequently, the production costs too.…”

“…A formula has been developed by Zemánek and coworkers [ 9 ] featuring similar properties as the available commercial products, but with reduced production expenses. The last paper dealing with ceramics [ 11 ] has a strong practical relevance since its findings, coming from a laboratory study on appositely clogged porous bricks, may be applied to daily maintenance of permeable pavements exposed to rainwater runoff and could positively affect their service life cycle.…”
