Abstract

Posebni beton pripada skupini posebnih betona a prvenstveno se koristi za izgradnju kolničkih površina, uglavnom parkirališta i cestovnih traka s manjim prometnim opterećenjem. Zamjenom konvencionalnih nepropusnih površina propusnim betonom utječe se na smanjenje otjecanja oborinskih voda, dopunjavanje razine podzemnih voda te općenito na poboljšanje kvalitete okoliša. U prvom dijelu rada dan je detaljan prikaz sastava i svojstava propusnog betona, kao i pregled propusnih betonskih kolnika, od projektiranja, ugradnje i trajnosti. U drugom dijelu rada prikazani su rezultati ispitivanja tlačne i vlačne čvrstoće uzoraka u starosti od 7 i 50 dana. Izrađene su četiri različite mješavine propusnog betona u kojima je variran sastav i udio pojedinih komponenata materijala. Cilj je bio ispitati prirast čvrstoća mješavina propusnog betona bez dodataka, i mješavina s dodacima silikatne prašine i polipropilenskih vlakana.

Abstract (english)

Pervious concrete belongs to the group of special concrete and is primarily used for the construction of pavement surfaces, mainly parking lots and road lanes with a lower traffic load. Replacing conventional impermeable pavement surfaces with pervious concrete reduces rainwater runoff, replenishes groundwater levels and generally improves environmental quality. In the first part of the paper, a detailed presentation of the composition and properties of pervious concrete is given, as well as an overview of permeable concrete pavements, from design, installation and durability. The second part of the paper presents the results of testing the compressive and tensile strength of samples at the age of 7 and 50 days. Four different mixtures of pervious concrete were made, in which the composition and share of individual material components were varied. The aim was to examine the strength gain of pervious concrete mixtures without admixtures, and mixtures with admixtures of silicate dust and polypropylene fibers.
