Summary: The excessive use of natural resources is caused by the increasing demand for infrastructure, while the marble industry produces a significant amount of waste that can be recycled. This research investigates the effects of substituting natural sand with marble waste on the properties of self-compacting mortar (SCM) and its durability against sulfate attack. The results show that up to 50% substitution of natural sand by marble waste can improve workability, strength, and durability of the mortar.

Summary: The purpose of this study is to examine the effects of partially replacing cement with a blend of marble waste powder and granite waste powder in mortar. The investigation included analyzing the properties of the waste powders individually and determining the optimal combination that yields the highest strength. The study found that a 50% blend of marble waste powder and granite waste powder produced the most substantial strength. As the proportion of the blend increased, the workability of the mortar mixes decreased, but incorporating the blend up to 15% resulted in enhancements in various physical and mechanical properties.

Summary: Recent developments in indirect predictive methods have led to promising solutions in energy consumption modeling. This study proposes and evaluates a new integrated methodology for estimating the annual thermal energy demand (D-AN), which is an indicator of building heating and cooling loads. The multilayer perceptron (MLP) neural network is trained using the symbiotic organism search (SOS) algorithm, known for its strength as a metaheuristic algorithm. Benchmark algorithms such as political optimizer (PO), harmony search algorithm (HSA), and backtracking search algorithm (BSA) are also used and compared. The results demonstrate that utilizing building properties within an artificial intelligence framework provides a suitable prediction for the D-AN indicator, and the suggested MLP-SOS model achieves accurate learning and reproduction of the nonlinear D-AN pattern with nearly 1% error and 99% correlation, outperforming other models like MLP-PO, MLP-HSA, and MLP-BSA. The discovered solution is expressed in an explicit mathematical format for practical applications in the future.

Summary: The increase in cement consumption has negatively impacted the environment due to the high energy consumption and release of poisonous gases during cement production. Scientists are now exploring the use of agricultural and industrial waste materials, such as millet husk ash, as supplementary cementitious material (SCM) in order to decrease cement manufacturing and energy usage, and enhance environmental sustainability. This research investigates the effects of incorporating different proportions of millet husk ash (0%, 5%, 10%, 15%, and 20%) on the workability, strength properties, water absorption, and drying shrinkage of concrete. The results show that replacing 10% of cement with millet husk ash leads to improved compressive strength, tensile strength, and flexural strength, as well as reduced water absorption and drying shrinkage.

Summary: Concrete, a top construction material worldwide, has a core weakness in low tensile resistance without reinforcement. To overcome this weakness, innovative materials like carbon fiber are being used to improve concrete mechanical strength and reduce embodied carbon. This study aims to investigate and optimize the use of carbon fiber for improving mechanical characteristics and reducing embodied carbon in concrete. The test results show that 0.6% carbon fiber is the ideal proportion for increasing compressive and split tensile strength. Response Surface Methodology (RSM) is applied to develop a model for calculating the impact of carbon fiber addition in concrete.

Summary: Rohtas Fort, a national heritage and UNESCO world heritage site in Pakistan, has deteriorated over time. One of the major issues affecting the fort is the decay of mortar, resulting in loosening of stone masonry walls. This study aims to analyze mortar samples from Rohtas fort and suggest a repair material compatible with the old mortar. The old mortar was characterized through various techniques, revealing it consisted of hydrated lime, broken bricks, sand, and clay. The modern mortar was prepared with similar ingredients, and its properties were found to be improved compared to the old mortar.
