Brizgani beton in njegova uporaba

projektna naloga

Abstract

Brizgani beton je tisti beton katerega transportiramo po tlačnih ceveh do mesta vgraditve in ga vgradimo z brizganjem. Pri tem načinu vgrajevanja betona, nanašamo beton s pomočjo stisnjenega zraka. Brizganemu betonu lahko dodamo tudi vlakna, da izboljšamo njegove lastnosti. Ideja, da v mešanico svežega betona ali malte primešamo vlakna anorganskega ali organskega izvora, se je porodila ob želji, da bi se v betonu izboljšale njegove lastnosti kot so: upogibna trdnost, žilavost in odpornost na utrujanje. S tem dosežemo zmanjšanje razpokanosti strukture. Danes za mikroarmiranje uporabljamo vlakna, ki so obstojna v alkalni cementni osnovi in bistveno izboljšajo lastnosti tako nastalega kompozitnega materiala.

Secondary title:	SHOTCRETE AND ITS USE
Secondary abstract:	Shotcrete is concrete, which is transported under pressure through pipes, do the place where is built in with shoting. Shotcrete is build in with the help of compressed air. To the concrete mixture we can also add some fibres to enhance its properties. An idea, to mix fresh concrete with organic or anorganic fibres, come of wish that properties such as: bending stiffness, stamina and resistance on fatique would improve. With that we can achieve reduction of cracks in the structure. Nowadays we use for microreinforced concrete fibres that are persistent in alkaline cement base, that essentially improve properties of so made composite material.
