Utilization of Advance Geopolymer in Concrete: A Review
Abstract: Climate change has several adverse impacts like changes in weather, untimely rains, depleting water, droughts, flash floods, acute and early summer and chilling winter. Equally, another bigger challenge to the society is foul smell whether it is river, pond, drain, public toilets or garbage dump yards. It is due to emission of hydrogen sulphide, methane and other toxic gases. Methane in pure form does not create any foul smell, however …

Prediction of Compressive strength of Periwinkle Shell Aggregate Concrete Using a Quadratic Polynomial Function
Abstract: In this study, a mathematical model is developed to predict the compressive strength of normal concrete made with periwinkle shell as coarse aggregate using a quadratic polynomial function. The response function is expressed as a multivariable function of the proportions of the component materials (water, ordinary Portland cement, sand and periwinkle shell). A total of thirty experimental runs were used to demonstrate the applicability of the mathematical model developed. The …

Assessment of Chloride Content in Plaster in Residential Buildings
Abstract: This study investigated the impact of chloride on building as per the age. Concrete samples were collected from buildings of different ages to measure chloride concentration. Findings revealed that chloride content increased with building age, potentially leading to decreased strength and damage. The research identified a significant concern of chloride-induced corrosion in older buildings, as chloride concentration increased with building age. To enhance the durability and safety of aging structures, …

Optimizing Aggregate Gradation for Enhancing Strength Properties of Pervious Concrete
Abstract: Pervious concrete possesses high permeability enabling environmental applications like stormwater recharging. However, lower strength limits widespread infrastructure adoption necessitating enhancements. This study focuses on optimizing aggregate proportions for improving compressive and flexural strength. Mixes were developed with cement variations from 200-500 kg/m3 with fine to coarse aggregates ratios systematically altered. Strengths were measured as per ASTM C39 and ASTM C78. Results showed reduced water-cement ratio and balanced aggregate blends improved …

Effect of Varying Shear Velocity on the Mechanical Behavior of Jointed Rock Subjected To Lower Normal Load
Abstract: : This study investigates the effect of shearing velocity on the mechanical behavior of rock joints, namely, the shear strength, residual strength, joint dilation, its surface roughness and the shearing stiffness under the application of lower normal load. The slower rate of shearing plays an important role in creep and the fatigue effect on jointed rock masses whereas, higher rate of shearing is experienced in the cases of dynamic loadings …
