“…Excessive cracking occurred at 1000ºC, and slight spalling was observed for fire duration of 8 & 12hrs on M4AlNs, M5AlNs, and M6AlNs concrete surface, and the color of the concrete surface changed to whitish. Mainly from Table 10, it is detected that as the temperature grew from 600 to 1000ºC, aggregates decomposed, the color changed to red, and binding properties are also lost [39]. From the visual observation shown in…”

Infrastructural development is multiplying worldwide, which has raised the demand for raw materials used in producing concrete [1]. Fine aggregates, coarse aggregates, and cement are used to make concrete. Cement acts as the glue that binds concrete together, but cement manufacturing causes significant environmental impact [2]. Extensive research is being done to create concrete to minimize this effect by finding an alternative to cement [2]. Supplementary cementitious materials (SCM) used entirely or partially as a substitute enhances concrete efficiency. Still, their reactivity is affected by factors such as chemical composition, surface area, shape, and size of the SCM, percentage replacement, and cement type [3]. Unique properties like high strength, compact morphology, reduced permeability, and enhanced durability are achieved using SCM to produce highperformance concrete [4].

“…After exposure to elevated temperature, the residual compressive strength is a major concern in the fire-resistant design. The strength degradation in concrete is changeable, and there are significant variations in strength loss; this behaviour is significantly related to the aggregate type [5,39]. As seen from the results plotted in Fig.…”

Concrete, the backbone of modern infrastructure, exhibits varying mechanical behaviour that depends on its components, with aggregates playing a crucial role in its strength and durability. This study aimed to investigate the influence of elevated temperatures on the compressive strength of concrete made with different types of aggregate. A comprehensive evaluation of concrete mixes was conducted using quartz, crushed clay bricks, crushed andesite, expanded clay and expanded glass coarse aggregates. For each coarse aggregate type, concrete mixtures were made with the same amount of Portland cement, water-cement ratio, natural sand, and superplasticizer. The effective water-cement ratio and cement content were kept constant in each concrete mixture. The grading and maximum particle size were the same in all concrete mixtures. The results revealed that the type of aggregate has a significant impact on the compressive strength and thermal resistance of concrete, with andesite-containing concrete exhibiting the highest residual strength after heating up to 800 °C and clay brick-concrete displaying the highest strength under elevated temperatures up to 1000 °C. The study also found that the age of concrete affects its strength at elevated temperatures, as concrete in the early stages of hydration is more susceptible to thermal cracking than concrete that has had more time to cure. Generally, the compressive strength of normal-weight aggregates depends on the strength of the parent rock. But in the case of fire (elevated temperature), the cement paste matrix loses its strength, and the aggregates effects become more significant.

“…The exposed circumstances [7][8][9][10] determines the structure's durability requirements, choice of materials, proportion, design and construction. As a result, if the exposure class is chosen correctly, it will provide great durability of concrete buildings, reducing routine maintenance and costs.…”

This research explores the testing of M40 grade concrete results under various exposure scenarios. The characteristics of concrete are investigated at the plastic and hardening stages. The characteristics of concrete at both stages vary depending on the exposure circumstances. The rheological qualities of the concrete as well as its strength characteristics under various exposure situations are investigated. It has been noted that as exposure conditions deteriorate, cement content gradually rises while W/C and water content decrease. This research is more beneficial for predicting the diverse properties of concrete under various exposure conditions. This will also aid in reducing losses incurred during construction and structural decay. During the investigation, the correlation matrix and Principal Component Analysis (PCA) are used to evaluate the interrelationship of the experimental variables, which yields more accurate results and predictions of the various characteristics of concrete. A Multivariate Linear Regression (MLR) model developed for the prediction of concrete qualities in the plastic and hardens stages. The MLR model found to be best matched to experimental data, and its forecast is correct. The Response Surface Method (RSM) used to find the optimal properties of the concrete in all types of exposure scenarios.
