ABSTRACT

Fires have the capacity to result in significant harm to both people and their belongings. Concrete is a primary structural material extensively utilized in construction because of its strength, durability, and ease of production, but its fire resistance is its most distinctive advantage over other construction materials. Yet, using cement in construction is gradually gaining global influence because of the increasing rate of carbon dioxide (CO₂) emission and global warming caused by it. So, in a trial to find a partial replacement for cement, this paper investigated how elevated temperatures affect compressive strength in slag and nano-modified concrete mixtures. Concrete mixtures, containing nanoclay replacing 0.3%, 0.5%, and 0.8% of cement by weight, and slag replacing 50% of cement by weight, were examined for compressive strength change in fixed temperatures fluctuating between 25℃ and 700℃ for 2 hours. Results showed that in the mixtures including NC and slag the compressive strength increased up to 300℃ and improved the compressive strength by 40%, 54%, and 44% respectively when exposed to 700℃ for 2 hours. Using NC and slag to the concrete mix leads to improvement in the compressive, tensile and flexural strength when compared to the control mix.
