pH-Responsive Smart Polymer Nanocomposites for Anti-Corrosive Coatings
Abstract: Metallic corrosion under adverse marine and industrial conditions imposes gigantic financial burdens and risks worldwide. Conventional waterproofing waterborne epoxy has passive barrier protection, but is also inherently microporous, lacking intrinsic repair ability against mechanical damage and thus rapidly decays. This is a critical gap that this work tries to bridge by designing a new pH-responsive hybrid polymer nanocomposite by using polyethyleneimine-tannic acid-cerium functionalized boron nitrate nanosheets with chitosan-capped mesoporous silica …

Investigation of Mechanical Properties of Hollow Bricks Incorporating Aerated Aggregates: A Polymer-Cement Composite Approach
Abstract: The rapid advancement of construction technologies has necessitated the development of lightweight, thermally efficient, and sustainable building materials. Hollow bricks, due to their inherent voids, offer substantial reductions in dead load and enhanced insulation properties. However, their mechanical performance often falls short when compared to conventional solid bricks. To address this limitation, this study explores the synergistic integration of aerated aggregates and polymer-cement composites (PCCs) in hollow brick production. Aerated …

Enhancing Compressive Strength and Durability through Optimization of Concrete Mixtures
Abstract: This research investigates how varying cement-aggregate ratio, water-cement ratio, and slump height affect the compressive strength of concrete mixtures. Through an analysis of 36 samples, each representing different combinations of these parameters, significant insights are gained into the optimization of concrete mix designs for construction applications. The study reveals that higher water-cement ratios tend to decrease compressive strength due to increased porosity in cured concrete. Conversely, higher cement-aggregate ratios generally …
