Photocatalytic Cement Mortar with Durable Self-Cleaning Performance

Catalysts, Год журнала: 2025, Номер 15(3), С. 249 - 249

Опубликована: Март 6, 2025

Nano-TiO2-modified mortars are fabricated by introducing TiO2 nanoparticles to the conventional mortar mix with designed mixing and curing procedures. It was found that additional can accelerate hydration improve air void distribution in matrix. The experiments also showed 0.5 wt.% 1 TiO2-modified has a comparable mechanical strength traditional cement mortar. abrasion resistance is improved at concentration. photocatalytic performance of confirmed methylene blue decomposition test. Finally, multi-physics computational model constructed assess effects coated on building quality improvements neighboring area. benefits affected different nano-TiO2 concentrations, as well wind conditions neighborhood. Overall, this study shows properly nano-TiO2-modified promising achieve multifunctional terms durability autogenous self-cleaning surrounding environment.

Performance of Nanotechnology in Cementitious Materials: Synthesis and Application

Materials, Год журнала: 2025, Номер 18(10), С. 2171 - 2171

Опубликована: Май 8, 2025

Cementitious materials are indispensable in the construction industry and urban development worldwide because cement pastes, mortars, concrete provide mechanical strength, high durability, excellent stability to various structures that used a lot of civil works. Owing impact relevance these materials, it is frequently seek ways improve their properties characteristics. In recent years, nanomaterials such as nanoparticles (NPs) nanofibers (NFs) has allowed cementitious mechanical, thermal, chemical, durability properties, among others. This can be associated with fact allow for improved hydration by retaining water mix, helping define more uniform microstructure and, therefore, significantly reducing porosity, which prevents contamination from entry external agents into structure. addition providing an overview effects using on enhancing this review includes most widely nanomaterial synthesis methods years contribution sustainable environmentally friendly construction.

Utilizing Nano-TiO2 and GGBS to Improve Concrete's Acid Resistance and Durability

Опубликована: Май 13, 2025

Concrete is a widely used material in construction, but it susceptible to deterioration when exposed acidic environments. This can lead significant structural damage and costly repairs. study investigated the durability strength characteristics of M40 M50 grade concrete with incorporation 1% titanium dioxide (TiO₂) 30% ground granulated blast furnace slag (GGBS). The performance this modified was assessed through various tests, including acid resistance rapid chloride penetration test (RCPT). evaluated effects exposure 5% sulphuric (H₂SO₄), hydrochloric (HCl), sodium sulphate (Na₂SO₄) over 28, 90, 180 days. results indicated that exhibited lower weight loss higher residual compressive compared conventional concrete. factor calculations confirmed mix demonstrated superior aggressive chemical Rapid Chloride Penetration Test (RCPT) measured total charge passed specimens assess ion permeability. showed reduction penetration, around (50-60) % permeability for (40-50) control mix, classifying within "very low" category.

Influence of Nanoparticles on the Mechanical and Durability Properties of Concrete: A Microstructural Analysis

E3S Web of Conferences, Год журнала: 2024, Номер 588, С. 03005 - 03005

Опубликована: Янв. 1, 2024

This study investigates the effects on mechanical and durability properties of concrete by including nano-silica, nano- titanium dioxide, nano-alumina. The mixes included nanoparticles in a range quantities, from 0.5% to 4% cement weight. Several experimental tests were performed, those for chloride permeability, workability, compressive strength, flexural strength. Compressive strength increased 40.5 MPa permeability decreased 1000 Coulombs, indicating an improvement durability, when nano-silica content was found be 3%. Nano-titanium dioxide nano-alumina also shown minor but noticeable improvement. A detailed SEM microstructural analysis demonstrates formation dense refined microstructure, lending credence claims improved properties. Results show that adding concrete, particularly increases its performance without reducing or durability.
