Structural and Luminance Properties of Light Transmitting Concrete
Bibliographic record
Abstract
Population growth and urbanisation have resulted in exploitation of natural resources, anomalous climate change and environmental pollution.Thus, there is a need for the development of new construction techniques that will not only ensure the preservation of natural resources but at the same time will focus in making a building that is energy efficient and environment friendly.Light transmitting concrete aims to meet such requirement which helps in bringing the minimisation of artificial energy usage by directly allowing the sunlight to project through a concrete material.This paper deals with the study of mechanical and optical properties of light transmitting concrete produced by the inclusion of 2mm diameter plastic optical fiber with four different densities in a concrete cube of dimension 150mmx150mmx150mm.The experimental results show that mechanical strength of concrete mixes containing plastic optical fiber (7x7) increases by 15.057% with light transmission intensity of 69lux greater than conventional concrete at 28 day age.Study also focused on evaluation of Rebound Hammer test results for concrete incorporated with Plastic Optical Fiber.Moreover, the stress-strain relationship showing actual behaviour of fiber concrete under compression is highlight in study.Based on the results it is concluded that the presence of plastic optical fiber in concrete material does not impair its mechanical properties and it represents a new way to harness the sun's energy because of its excellent light transmission capacity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
