Investigation Of The Engineering Characteristics Of Translucent Concrete

Abstract

This research investigates translucent concrete as a structural material that blends strength with visual appeal. Optical fibres were incorporated into M20-grade concrete at varying dosages (0.5%, 1.0%, and 1.5%) to evaluate their performance relative to conventional concrete. A range of laboratory tests—including compressive and flexural strength tests, non-destructive methods like ultrasonic pulse velocity and rebound hammer, and specialised assessments such as drop weight impact and light transmission—were conducted. Findings revealed that incorporating up to 1.5% fibre content led to approximately 10% and 15% improvements in compressive and flexural strength, respectively, while also enhancing impact resistance and internal consistency. The fibres also enabled effective light transmission, creating an aesthetically pleasing and energy-efficient material. In summary, the study demonstrates that translucent concrete offers a viable and sustainable solution for modern construction by merging structural integrity with architectural innovation.
