Effect of high‐range water reducer and W/C ratio on the fresh and mechanical properties of fiber‐reinforced natural zeolite SCC

open access: yesStructural Concrete, Volume 25, Issue 5, Page 4075-4102, October 2024.
Abstract The present study aims to investigate how the use of high‐range water reducer (HRWR) and variations in water/cement (W/C) ratio affect the properties of self‐consolidating concrete (SCC) while taking into account different proportions of polypropylene fibers (PF) and natural zeolite (NZ). A total of 28 samples were cast and analyzed.

New perspectives on carbon reinforced concrete structures—Why new composites need new design strategies

open access: yesCivil Engineering Design, Volume 5, Issue 5-6, Page 67-94, January 2024.
Abstract In civil engineering, carbon is typically regarded as a modern material to serve as reinforcement in concrete structures. Compared to steel reinforcement, it features two substantial benefits: It is not sensitive to corrosion, and has an enormously increased tensile strength.

Activated Bentonite for Physical, Mechanical, and Durability Properties of Concrete—A Review

open access: yesAdvances in Civil Engineering, Volume 2024, Issue 1, 2024.
Bentonite mostly exists in many counties and studies reported employment of activated bentonite in the concrete improves concrete performance more than using raw bentonite. However, it is not well‐known which range of bentonite activation temperature and employment dose gives the best concrete performance for the sustainability of activated bentonite ...
