Effect of temperature on the compressive strength and sustainability of expanded clay lightweight basalt fiber reinforced concrete

Concrete exposure to high temperature is a threat to the concrete which leads to loss of strength and degradation of the concrete. Based on this, it was necessary that the behavior on compression of lightweight expanded clay basalt fiber reinforced concrete (BFRC) be investigated when exposed to high temperature. The parameters and dosages of basalt fiber in lightweight expanded clay concrete have effects on the strength of the concrete. The sustainability of a structure in any environment is of high importance therefore, the types of material used as an aggregate and reinforcement must be durable, trustworthy and with the necessary properties suitable for the structure. The main aim of this paper is focused on the ability of lightweight expanded clay basalt fiber reinforced concrete when exposed to high temperature and tested for compressive strength, not to lose its total strength whereby, creating opportunity for the reuse of the concrete. The method of this research is based on laboratory test and practical review analysis. From the compressive strength, a view on the sustainability of this type of concrete is discussed. In this paper, the two sets of specimens were placed on three temperature ranges in a specific time interval. After, they were tested for compression. From the result, it was seen that expanded clay lightweight basalt fiber reinforced concrete didn't lose much strength under compressive test after it was exposed to high temperature thereby making the concrete sustainable to high temperature. © 2019 IOP Publishing Ltd.
