Dimensional stability and water transport behavior of concrete with high contents of wind‐turbine blade waste

Structural Concrete, Volume 27, Issue 1, Page 758-776, February 2026.
Abstract Fiber addition is a common strategy to enhance concrete's durability, avoiding cracks and reducing penetration of harmful agents. In this research, a sustainable fiber‐like material obtained from mechanical recycling of dismantled wind‐turbine blades and made up of glass fiber‐reinforced polymer (GFRP) fibers and microfibers, balsa wood, and ...

Pengaruh Variasi Agregat Kasar Penyusun beton Terhadap Kerapatan Beton Dengan Menggunakan Transmission Time Pada Alat UPV (Ultrasonic Pulse Velocity)

Rekayasa Sipil, 2019
To find out the quality of concrete, we need to test the concrete. Which is non destructive test or testing without damaging the test object, namely with an UPV (Ultrasonic Pulse Velocity). In this study using 4 variations of coarse aggregate composition (mix design), namely porous variation, RCA (Recycled Coarse Aggregate) variation, pumice variation ...

Elastic Properties of Concrete Incorporating Ogugu Lateritic Sand as Fine Aggregate

The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
This study investigates the substitution of conventional fine aggregate with Ogugu lateritic sand in concrete grades 25 and 50, focusing on elastic behavior and strength development. The results show that laterized concrete achieves significant strength gains over time, with grade 25 compressive strength increasing from 14.11 N/mm2 at 3 days to 32.27 N/

Effect of Bacillus amyloliquefaciens Bacteria–Coated Jute Fiber on Workability, Durability, and Microstructural Properties of Concrete

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Concrete’s durability is often compromised by low tensile strength, cracking, and limited self‐repair. Natural fibers like jute offer reinforcement but may absorb moisture, negatively affecting workability and durability, necessitating additional mortar for optimal performance.

Comparison of Pulse-Echo Tomography and Through-Transmission Ultrasonic Test for UPV Characterization of Building Materials

Infrastructures
Ultrasonic pulse velocity (UPV) is a widely used technique for diagnosis and structural safety assessment of existing buildings. The main difficulties in UPV tests on-site are due to one-sided accessibility of materials and degraded/irregular surfaces ...

Effect of Cement Types on Mechanical Strength, Durability, and Unit Production Cost of Concrete

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The primary aim of the present study is to identify the optimal cement type by jointly assessing mechanical performance, durability performance, and cost‐effectiveness using multicriteria decision‐making (MCDM) approaches. This study investigates the effects of four cement types commonly used in Bangladesh—CEM I/OPC, CEM II/A‐M (S‐V‐L), CEM II/B‐M (S‐V‐

Experimental Study on Influence of Sporosarcina ureae Bacteria on Mechanical and Fresh Properties of Self‐Healing Concrete With Focus on Elemental/Microstructural Analysis

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Concrete is the most widely used construction material globally, but it is inherently prone to various factors such as environmental conditions, mechanical stress, and chemical reactions. Stresses such as cracks can significantly reduce the lifespan of concrete structures, leading to increased maintenance costs and environmental impact.
