Influence of Agricultural Waste Materials in Concrete: A Sustainable Approach
Abstract: Urbanization and resource depletion have intensified the need for sustainable alternatives to traditional construction materials. The concrete industry, a major contributor to environmental issues due to cement production, is turning to waste materials to mitigate its impact. This review paper focuses on the use of agricultural waste as a partial replacement for cement and aggregates in high-strength concrete (HSC), with an emphasis on its influence on both fresh and hardened …

Development and Performance Evaluation of Polymer-Modified Geopolymer Composites Incorporating GGBS
Abstract: This research investigates the development and performance of geopolymer-based composite materials formulated using Ground Granulated Blast Furnace Slag (GGBS) as a reactive mineral component within an aluminosilicate polymer matrix. The study aims to create an eco-efficient and structurally sound inorganic polymer composite comparable to M35-grade concrete, produced entirely under ambient curing conditions. A series of mixes with varying GGBS replacement ratios (0–100%) was prepared, maintaining a constant binder content of …

Gastro Retentive Drug Target System: Its Needs, Advantages, Limitation and Approaches
Abstract: Background: Gastro retentive drug delivery systems (GRDDS) address limitations of oral therapy for drugs with poor solubility, instability at intestinal pH, or narrow absorption windows by prolonging gastric residence and increasing contact with the gastric mucosa. Objectives: To review GRDDS approaches—floating systems, mucoadhesive systems, and super porous hydrogels—with emphasis on formulation strategies and polymer–excipient selection to enhance gastric retention, modulate buoyancy/swelling/adhesion, and ultimately improve oral bioavailability and therapeutic outcomes for …

Adsorption, Process Technology with Catalysis
Abstract: Surface of solids assumes a significant part in numerous physical and synthetic peculiarities. There are two principle purposes behind this exceptional job. First and foremost, the outer layer of a substance interfaces first with its environmental factors. Furthermore, the surface particles are in an alternate state as looked at to the atoms in the inside of the strong. The surface atoms interface all the more promptly with different substances which …

Improving Photocatalytic and Antibacterial Properties of Zein/Polyvinyl Alcohol Polymer Composite Film by Dispersing TiO2 Nano Particles
Abstract: Zein/polyvinyl alcohol/nano-TiO2 composite film was effectively blended using a solution casting method. Mechanical, photocatalytic, and antibacterial properties of the composite film were evaluated. The breaking elongation of the composite film increased up to the maximum loading of 0.4% of nano-TiO2. The humidity and moisture content relationship was estimated with standard modified models of Halsey, Oswin, Chung Pfost, and Henderson. It was found that the Halsey model was the most suitable …

Review on Sustained Released Matrix Tablet
Abstract: Pharmaceuticals often use sustained release dose forms to prolong the therapeutic agent’s presence in the bloodstream and maintain a consistent plasma profile. The matrix governs the drug’s release rate. Hydroxypropyl methyl cellulose, a release retardant, is a key excipient in formulations due to its ability to promote sustained release. Techniques that include wet granulation, direct compression, or the dispersion of solid particles within a porous matrix, integrating polymers, like polymethyl …

Plant Bioactive Metabolites and Their Role in the Prevention and Control of Dental Diseases and Infections.
Abstract: The oral diseases, including dental caries and periodontitis, affect masses worldwide, and have historically been managed with synthetic antimicrobials that cause deleterious side effects, leading to mounting bacterial resistance. Consequently, contemporary dentistry is rapidly shifting toward phytomedicine using plant bioactive molecules, such as polyphenols, terpenes, anthraquinones (berberin, eugenol, curcumin, catechins, allicin, and azadirachtin. These compounds offer potent antimicrobial, anti-inflammatory, and tissue-regenerative properties that are crucial for preventing and curing dental …

Microstructural Evolution and Mechanical Performance of Ambient-Cured Fly Ash–Metakaolin Inorganic Polymer Composites Activated by Anhydrous Sodium Silicate Powder
Abstract: Inorganic geopolymer networks offer a low-carbon and sustainable solution to traditional binder systems through the alkali-activation of industrials-grade aluminosilicate material. The present paper focuses on the microstructure development and the mechanical performance of the ambient-cured fly ash – metakaolin inorganic polymer composite activated with solid anhydrous sodium silicate powder. Five inorganic polymer binder combinations were formulated by replacing fly ash with metakaolin at mass fractions of 0%, 10%, 20%, 30%, …

Performance of Concrete in Chemically Aggressive Environment by Using Cementitious Materials in Concrete
Abstract: This study investigates the performance and durability of sustainable concrete incorporating industrial and agricultural waste materials specifically Fly Ash, nano silica and Graphene Oxide when subjected to chemically aggressive environments. Traditional Ordinary Portland Cement (OPC) concrete often suffers from micro-structural degradation, sulfate attack, and acid penetration in harsh conditions. However, the integration of pozzolanic wastes creates a synergistic effect that densifies the concrete matrix through secondary C-S-H (Calcium Silicate Hydrate) …

Optimized Utilization of Kota Stone Slurry Waste in Fly Ash–Based Geopolymer Mortar: A Taguchi-Driven Approach
Abstract: The large-scale generation of stone-processing wastes presents a critical sustainability challenge and an opportunity for value-added reuse in construction materials. This study develops a high-performance fly ash geopolymer mortar by partially replacing Class F fly ash with Kota stone slurry waste (KSSW) and optimizing the key mix parameters using a Taguchi design framework. Five governing factors—binder replacement level, NaOH molarity, sodium silicate–to–sodium hydroxide ratio (SS/SH), curing temperature, and alkaline solution-to-binder …
