Ready-Mix Mortar Air Entrainment with Admixtures and Mixing Times

An experimental study of 36 mortar mixtures prepared with varying mixing times, admixture contents, and aggregate sizes. The research evaluated the influence of air entraining admixtures (AEA), hydration stabilising admixtures (HSA), aggregate type, and mixing time on air entrainment in ready-mix mortars. The dataset likely contains results from this controlled laboratory investigation, authored by Juliana Pippi Antoniazzi.

Use Cases

• Modeling the relationship between mixing time and air entrainment based on the described 150-330 second range
• Analyzing the effect of admixture content (AEA 0-0.5%, HSA 0-0.9%) on mortar properties
• Comparing the influence of sand particle size on air entrainment in mortars with and without AEA

Strengths

• Experimental design includes 36 distinct mortar mixtures, allowing for controlled comparisons
• Specific, quantitative variables are described, including mixing times (150, 210, 270, 330 s) and admixture percentages

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download
• Last update date is unknown; freshness unverified
