Effect of the Replacement of Cement by Fly Ash and Calcined Clay on the Mechanical-Physical Properties of Conventional Mortar
Bibliographic record
Abstract
This article explored the effects of replacing Portland cement with fly ash and calcined clay on the strength and durability of conventional mortar, focusing on improving its mechanical properties and reducing the carbon footprint generated by the construction industry.Tests were conducted on samples with 20% and 55% cement replacements ratios, evaluating parameters such as compressive strength, flexural strength, and porosity.The results indicated that mortars with cement replacements outperformed the control mortar in terms of strength and compaction.At 28 days, the mortar with a 20% replacement achieved a compressive strength of 24.67 MPa, surpassing the standard design.Lower porosity was also observed in mortars with replacements, contributing to greater durability and resistance to water absorption.This study concluded that using fly ash and calcined clay as a partial replacement for cement was viable for structural applications, particularly in seismic zones, due to improved cohesion and reduced formation of voids in the mix, enhancing its mechanical performance and reducing its environmental impact.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
