“…The loading plot in Figure 3 (B) (ii) illustrates the significance of the components for the study's variables. In order to predict the various properties of concrete, Patil et al [19] and Lu et al [20] employ correlation matrices; this plot also helps to condense a large number of unimportant variables.…”

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.

“…This is utilizing worldwide as an alternative to conventional concrete due to its tremendous performance [1,2]. The characteristics of the composites, such as high strength, self-consolidation, crack resistance, etc., are mainly dependent on the properties of the materials [3,4]. A high dosage of cement in the preparation increases the strength.…”

A versatile concept in the field of Engineered Cementitious Composite (ECC) is Eco-friendly ECC. The materials and properties of specimens will influence the characteristics. In this present study, locally available fine aggregates (50% River sand + 50% M-Sand (16.3316 0 N, 80.3514 0 E)) and 2% PVA fibers-based Mix-1, local sand and sisal fibers based Mix-2 (1% sisal fibers + 1% PVA fibers) are considered. The flowability is slightly reduced from Mix-1 to Mix-2. All considered mixes showed good self-consolidation properties (Deformability factor (D.F.) <2.75 based on Li, 2008). For analysis of the mechanical characteristics, different specimens are considered. The compressive and flexural properties negligibly reduced by the size of specimens. But compressive strength moderately reduced by shape (cube to cylindrical specimens). The compressive ratio is between 1.45 to 1.6. The split tensile properties are moderately reduced with the size specimens. All these mechanical characteristics are slightly reduced by the usage of sisal fibres. To determine the durability properties, Rapid chloride penetration (RCPT) test conducted. However, these properties also negligibly influenced by the sisal fibres. It indicates that the sisal fibres can be used for the partial replacement of PVA fibres in the local sand-based mixes. To analyse this, SEM and XRD analysis conducted. Their performance also validated based on Roychand et al, 2016. The hydration of particles and arrangement of fibres are responsible for the significant performance of this Eco-friendly ECC.
