Coating Mortar Mix Design with Artificial Crushing Sand

An experimental study proposing a mix design method for coating mortars using artificial crushing sand as fine aggregate. The method was assessed using tests for air content, compressive strength, flexural strength, adherence, modulus of elasticity, water absorption, porosity, cracking, and stereoscopic images. The research was conducted by White José dos Santos and concludes the method is efficient for producing good quality mortars under ABNT NBR 13281:2005 specifications.

Use Cases

• Optimizing mortar mix proportions based on experimental test results for compressive and flexural strength.
• Analyzing material properties like water absorption and porosity to predict mortar durability.
• Developing standardized mix design procedures for external coating mortars using artificial sand.
• Statistical analysis of material performance to validate new construction methods.

Strengths

• Method assessed using nine specific material tests, including compressive strength and modulus of elasticity.
• Explicitly designed to meet the specifications of the ABNT NBR 13281:2005 standard.
• Uses specific material components: Portland cement type II with blast furnace slag, hydrated lime type I, and gneiss artificial crushing sand.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
