Abstract

U ovom radu se opisuje propusni beton, čija je najveća primjena u gornjem ustroju betonskih kolnika, uglavnom za parkirališta i manje cestovne trake za manja opterećenja, odnosno kao propusne baze i rubni slivnici. U radu su prikazani istraženi primjeri propusnog betona, njihovi sastavi, bitne značajke u svježem i očvrsnulom stanju, te rezultati i analize. Izrađene su četiri različite mješavine u kojima je variran sastav i udio pojedinih materijala. Varirani parametri su: vodocementni omjer (v/c), granulometrijski sastav, odnosno veličina najvećeg zrna DMAX, dodatak silikatne prašine, aeranta i polipropilenskih vlakana. Ispitana su svojstva u svježem stanju, kao što su konzistencija, gustoća i temperatura. U očvrsnulom stanju ispitana je tlačna i savojna čvrstoća, protočnost, te količina šupljina u betonu.

Abstract (english)

This thesis “Porous concrete in continental conditions” describes porous concrete, the largest application of which is in the upper structure of concrete pavements, mainly for parking lots and smaller road lanes for light loads, like permeable bases and edge drains. Examples of porous concrete, their compositions, essential fresh and hardened properties, results and analyzes are presented in the thesis. Four different mixtures were made in which the composition and the proportion of individual materials varied. The varied parameters are: water-to-cement ratio (v/c), particle size distribution, or size of the largest DMAX grain, addition of silica fume, aerant and polypropylene fibers. In fresh condition such as consistency, density and temperature were tested. In hardened condition, the compressive and flexural strength, water permeability, and the amount of cavities in concrete were tested.
