Abstract

V gradbeništvu je poznanih več gradbenih materialov, vodilno vlogo pa ima beton. Beton lahko kot izboljšavo za boljše zadrževanje toplote vsebuje dodatke fazno spremenljivih materialov (angl. PCM – phase change materials). Primer takih materialov so voski. Zaradi fazne spremembe (trdno–tekoče) zadržujejo toploto, ki ji rečemo latentna toplota. Obstajajo trije tipi PCM materialov, in sicer organski, anorganski in evtektični. Materiali s fazno spremembo se lahko betonom dodajajo z različnimi tehnikami, kot sta na primer enkapsulacija in porozna vključitev. Dodatki PCM k betonu vplivajo na strukturo in posledično na trdost ter funkcionalne lastnosti. Prav tako lahko vplivajo na varnost v primeru požara. Velik utežni faktor pri izboru betona z dodatkom PCM ima cena.

Secondary title:	Modern concretes with the addition of phase change materials
Secondary abstract:	Several building materials are known in the construction industry, with concrete playing a leading role. Concrete can contain phase change materials (PCMs) as an enhancement to improve heat retention. Waxes are an example of such materials. They retain heat, called latent heat, because of their phase change (solid - liquid). There are three types of PCM materials: organic, inorganic and eutectic. Phase change materials can be added to concrete using various techniques such as encapsulation and porous incorporation. The addition of PCM to concrete, affects the structure and consequently the strength and other functional properties. They can also affect safety in case of a fire. Price is a major factor in the selection of concrete with PCM.
