There has been widespread waste of natural resources in the construction industry over the course of many decades. It is also crucial to increase the use of environmentally friendly supplies in the development of concrete structures in light of the fast environmental deterioration and consequent pollution. Because of its capacity to modify the concrete's behaviour after being subjected to high temperatures, perlite powder (PP) has recently been the focus of scientific attention as a naturally accessible sustainable additive. The goal of this study is to test the feasibility of using PP in high-temperature concrete. Following this line of thought, the author created not one but two novel concretes: a Perlite Binary Concrete (PBC) made from PP and cement, and a Ternary Blended Concrete (TBC) made from PP and Silica Fume (SF) in lieu of cement. In addition to the Controlled Concrete (CC) and the Portland Blained Concrete (PBC), we also created four TBC mixes by varying the percentage of PP used to replace the cement from 1% to 7% in 2% increments. Samples are air-dried after being heated to temperatures between 200 and 800 degrees Celsius at a rate of 200 degrees Celsius per hour for 7, 28, 56, and 90 days. Mechanical, durability, and microstructural tests, as well as an inspection of TBC and PBC samples, were conducted. These studies show that PBC with 5% PP substitution is the strongest and has the best thermal properties.
