Concrete Hardness Tests with Polypropylene Microfiber Additives and Curing Variations

An experimental study evaluated the influence of polypropylene microfiber content (0, 600, and 900 g/m³) and three curing conditions on concrete floor properties. Tests performed included bleeding, compressive strength, and surface hardness using a rebound hammer. The results indicate that a 600 g/m³ microfiber content presented better performance in the analyzed properties.

Use Cases

• Analyze the effect of polypropylene microfiber dosage on concrete bleeding based on the described experimental setup.
• Compare compressive strength results across different curing conditions mentioned in the study.
• Evaluate the relationship between surface hardness measured by rebound hammer and other concrete properties.
• Identify optimal microfiber content for concrete floor applications based on the performance results.

Strengths

• The study explicitly tests three specific microfiber dosages (0, 600, and 900 g/m³).
• Three distinct curing conditions (without cure, wet cure, and wet cure after three days) were evaluated.
• Multiple standardized tests (bleeding, compressive strength, surface hardness) were performed.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect the specific experimental bias inherent to a single academic study.
