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.

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 ...

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.

Functional Performance and Comparative Sustainability Assessment of Cementitious Composites Using Supplementary Cementitious Materials (SCMs)

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
To evaluate the potential of fly ash (FA) and ground granulated blast furnace slag (GGBFS) as supplementary cementitious materials (SCMs) in terms of sustainability and functional performance, both concrete and mortar samples were prepared with GGBFS or FA at moderate to high replacement ratios (35%, 50%, and 65%) and were tested for compressive ...
