Rubber concrete (RubCon) is a new polymer composite material created and studied by the research team of the Voronezh State University of Architecture and Construction (Russia) and the Israel company Polymate Ltd.-INRC.

Development of a manufacturing process for diene oligomers belonging to a liquid rubber class with viscous liquids consistence allowed us to create a new class of conglomerate polymer composite materials—rubber concrete (RubCon). Rubber concrete is an advanced construction material created over the last few years. It is polymer concrete with a unique set of physical-mechanical, chemical, and technological properties that allow the creation of highly effective building structures and products. 

As in other polymers, rubber concretes form three kinds of deformation elastic, viscous, and highly elastic in a stress field (Figure 2.42). 

As rubber concrete has long-term strength that is distinct from zero and creep damped out at compression, it is necessary to enter element E representing an elastic molecular skeleton of a material into the rheological material circuit (Figure 2.43). 

Because Formula (2.45) is identical to the experimentally obtained Formula (2.41), it is obvious that the structural diagram (Figure 2.44) adequately describes the behavior of rubber concretes at compression and can be added to the basis of the creep equation of these materials. (The similar diagram corresponds to a number of plastic [rigid PVC, polyethylene] and furan polymeric concrete.)... 

Creep deformation of rubber concretes has a damping character. 

The manufacturing finishing process of rubber concrete is vulcanization of the mixture. The mode of hardening (vulcanization) and RubCon s final characteristics depend on the temperature and heating time of RubCon articles. The structure of the composite depends on the time delay before the mixture is heated, the environment in which it is hardened, and the temperature and pressure exerted during hardening. 

Analysis of the temperature field allows a determination of the possibility of structure formation of the rubber concrete throughout the volume of vulcanized covering. The temperature field of the vulcanized covering has a small dispersion... 

The efficiency of vulcanization and structure formation of rubber concrete can be considerably increased by supplementary thermal treatment of the outside of the covering, thereby creating a more uniform thermal field along the surface and volume of the heated article. 

Increase of thermal field uniformity, which positively affects the strength characteristics of the rubber concrete...
