Porozni (propusni) beton je ekološki prihvatljivo rješenje u odnosu na nepropusnosti konvencionalnih betona. Porozni beton najčešće se sastoji od mješavine cementa, krupnijeg agregata i vode. Djelomičnim ili potpunim uklanjanjem sitnog agregata dobiva se porozna struktura koja zatim utječe na svojstva poroznog betona. Cilj je ovog rada opisati glavne čimbenike koji utječu na mješavine poroznog betona, odnosno zbijenost, omjer agregata i cementnog materijala (ACR), udio pijeska, omjer vode i cementnog materijala (v/cm), veličina krupnog agregata i udio šupljina ili poroznost. Također, u radu se raspravlja i o učincima različitih dodataka, zamjenskih materijala i vlakana u mješavinama. Rezultati pokazuju da porozni beton djeluje kao učinkovit medij u promicanju održivosti urbanih sredina zbog svojih višestrukih koristi., Pervious concrete is an environment friendly solution for eliminating imperviousness-related drawbacks of conventional concrete. Pervious concrete mixes are predominantly composed of cement, coarse aggregate, and water. The partial or complete elimination of fine aggregate results in porous structure, which influences performance of pervious concrete. This article is aimed at reviewing major factors involved in the design of pervious concrete mixes, namely the compaction, aggregate to cementitious material ratio (ACR), sand fraction, water to cementitious material ratio (w/cm), size of coarse aggregate, and void ratio or porosity. The effects of various admixtures, replacement materials, and fibres, are also discussed. The results indicate that pervious concrete acts as an effective medium in promoting the sustainability of urban environments due to its multi-aspectual benefits.
