Effect of superplasticizer in geopolymer and alkali-activated cement mortar/concrete: A review

REVIEWS ON ADVANCED MATERIALS SCIENCE, Год журнала: 2024, Номер 63(1)

Опубликована: Янв. 1, 2024

Abstract The cement and construction industry creates around 10% of the global carbon footprint. Geopolymer alkali-activated concrete provide a sustainable solution to conventional concrete. Due its disadvantages, practical usage geopolymer is limited. Workability one issues faced in developing concretes. Plenty research was conducted enhance ability use different superplasticizers (SPs). present article extensively reviews effects SPs on articles published last 5 years high-quality journals are considered for chemical composition analyses their exact impact mortar Later, normal consistency setting times mortar, workability, compressive strength, flexural split tensile microstructure, water absorption determined. improve concretes upon desired dosages; more dosage leads negative effects. Therefore, selecting optimal superplasticizer essential since it impacts performance

A Comprehensive Review of Sustainable Geopolymer Concrete Using Palm Oil Clinker: Environmental and Engineering Aspects

Energy Science & Engineering, Год журнала: 2025, Номер unknown

Опубликована: Фев. 9, 2025

ABSTRACT Amidst the dual challenges of aggregate scarcity and environmental impact carbon dioxide (CO 2 ) emissions from cement production, this study investigates viability palm oil clinker (POC) as a sustainable in geopolymer concrete (GPC). The lack appropriate alternative coarse fine aggregates essential production is one critical issues faced by construction industry. This review evaluates its benefits, chemical physical attributes, influence on GPC's microstructure. Previous studies have shown that incorporating POC GPC significantly reduces density 2345 to 1821 kg/m 3 while maintaining competitive compressive strength, thus proving applicability various structural nonstructural contexts. Moreover, with demonstrates enhanced resistance aggressive conditions such water absorption against acid sulfate environments. Geopolymer mortar (GPM) exposed attack recorded lowest decrease strength than GPM containing about 20%. use 100% mix has 3.2% absorption, which lower limit for high‐performance concrete. results advocate development POC‐aggregate an environmentally friendly material, contributing advancement building

An Overview of the Effects of Incorporating Glass Fiber on Mechanical Properties of Cementitious Composites

IGI Global eBooks, Год журнала: 2025, Номер unknown, С. 473 - 502

Опубликована: Апрель 11, 2025

Cementitious composites are widely used building materials for their good workability, strength, and durability. However, they generally brittle, leading to failure without warning. This resulted in new ideas incorporate fibers into the composites, aiming increase reduce cracks, improve impact resistance. Glass fiber is a thin-strand material made from silica-based glass. It recognised its high tensile low density, ability enhance cementitious composites' flexural strength. review paper provides an overview of glass fibers, including composition, properties, classification. then explores effects content on mechanical properties composites. also discusses role distribution, fiber-matrix interactions, development internal networks within composite. The concludes with recommendations future research optimise use further properties.

Compressive and tensile strength estimation of sustainable geopolymer concrete using contemporary boosting ensemble techniques

REVIEWS ON ADVANCED MATERIALS SCIENCE, Год журнала: 2024, Номер 63(1)

Опубликована: Янв. 1, 2024

Abstract Geopolymer concrete (GPC) serves as an environmentally conscious alternative to traditional concrete, offering a sustainable solution for construction needs. The ability make on-site changes is dependent on the concrete’s strength after casting, which must be higher than target value. To anticipate before it poured is, thus, quite helpful. Three ensemble machine learning (ML) approaches, including gradient boosting, AdaBoost regressor, and extreme are presented in this work potential methods forecasting GPC’s mechanical that incorporates corncob ash. determine modeling parameters crucial, sensitivity analysis was employed. When compressive split-tensile of GPC were tested with ML models, R 2 values more 90% discovered between predicted actual results. Statistics k -fold based error coefficient determination used verify developed models. Slag amount, curing age, fine aggregate quantity three mix proportions had most impact strength, shown analysis. results study demonstrated boosting approaches could reliably estimate strength. Incorporating such procedures into quality control can yield significant improvements.
