Trdnost penastega betona

Pena beton je odličen gradbeni material. Prihrani delo in stroške gradnje, je bolj odporen na spremembe temperature, in zahteva veliko manj vzdrževanja kot standardni liti beton. It can be used for a wide variety of applications, from insulating roofs and walls to filling voids in buildings and sewers. Foam concrete is even an ingenious way to deal with abandoned underground pipes and caissons.

As with all types of concrete, foam concrete strength depends on the materials and production methods used to manufacture it. Foam concrete can be made stronger, lighter or more fluid through varying the proportion of different ingredients. It can also be altered to suit specific applications by adding different foaming agents, primesi, in agregati.

Trdnost penastega betona je povezana predvsem z njegovo suho gostoto, z večjo gostoto, ki daje večjo trdnost. Gostoto penastega betona je mogoče povečati z uporabo dodatnih cementnih materialov, kot je leteči pepel ali zmleta granulirana plavžna žlindra (GGBFS). Na splošno, uporaba GGBFS zmanjša količino potrebnega cementa in poveča trdnost in stroškovno učinkovitost mešanice. Trdnost penastega betona lahko povečamo tudi z dodajanjem silicijevega dioksida, kar poveča prepustnost celičnih sten.

Pričakuje se, da se bo trg penjenega betona v naslednjih nekaj letih močno povečal, zaradi vedno večjega števila novih infrastrukturnih projektov. Evropa je posebej obetavna regija, as it is seeing major investments in modernizations and has strict regulations regarding the use of foam concrete. Poleg tega, it is possible that Latin America will also experience significant growth, thanks to government initiatives and regulation.
