Heat influence on sustainable rubberized concrete mixes

Rubberized concrete (Rubcrete) usually minimizes concrete brittleness and increases conventional concrete’s energy absorption as well as the brittleness. Exposing elevated heat deteriorates the strength of traditional concrete and causes rubber dilution. The article investigated replacing aggregate with rubber to enhance the dynamic properties of concrete and discussed many parameters like replacement type, replacement amount, effect of heat and heat increment. Also, many properties, such as unit weight, compressive strength, tensile strength and modulus of rupture, were investigated and discussed for two types of rubber versus aggregate replacement and 10%,20% and 30% percentages. It was concluded that the rubcrete strength was reduced more than the normal concrete due to the presence of rubber, which made the rubber melt inside the concrete pores and caused internal residual stresses due to the hydrostatic pressure. It’s not recommended to use rubberized concrete in construction sites exposed to high-temperature rise, like baking ovens or nearby, because the rubberized concrete loses its strength to the fourth or half after exposure to heat.
