Influence of Cellulose Ethers on Bedding Mortar Properties in Concrete Masonry

Alexandre Lima de Oliveira's study investigates the influence of Hydroxypropylmethyl cellulose (HPMC) on cement-lime based bedding mortar for concrete structural masonry. The dataset likely contains measurements from mortar samples with HPMC proportions of 0.00%, 0.03%, 0.06%, and 0.09% of total dry weight, evaluating properties in fresh and hardened states. Results indicate increased water retention but reduced joint compressive strength, modulus of elasticity, and bond strength in flexion when cellulose ether was used.

Use Cases

• Modeling the relationship between cellulose ether concentration and mortar water retention capacity based on the described experimental proportions.
• Predicting the compressive strength of masonry prisms based on the described mortar formulations and test results.
• Analyzing the trade-off between improved water retention and reduced bond strength in flexion for mortar admixture design.

Strengths

• The study explicitly tests four specific HPMC concentration levels (0.00%, 0.03%, 0.06%, 0.09%).
• Evaluates multiple mechanical properties including compressive strength, modulus of elasticity, and bond strength as described.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
