TN Index – Technical Notes Index
Technical Notes provide practical engineering guidance on concrete technology, construction quality, troubleshooting and best practices. Developed through industry experience and professional discussions, these resources help engineers apply practical solutions to real construction challenges.
DMSA Technical Notes are developed by SM Ecosystems to help engineers, consultants, contractors, quality professionals and project teams investigate, understand and solve real-world concrete and construction challenges through engineering principles, systematic investigation and practical engineering solutions.
Browse our Technical Notes, Engineering Case Studies, Engineering Standards, Standard Operating Procedures (SOPs) and QMS Manuals through the SM Knowledge Hub.
Technical Notes Library
Browse the complete collection of DMSA Technical Notes. Each Technical Note addresses a specific engineering challenge and provides practical guidance for investigation, root cause analysis, engineering evaluation and recommended corrective actions.
Technical Notes are prepared to support informed engineering decisions by combining field experience, technical expertise and practical problem-solving. Each note focuses on addressing common construction challenges through clear recommendations that can be applied directly on site.
The Technical Notes Library will continue to expand with new publications covering concrete technology, quality management, durability, precast construction, engineering investigations and construction best practices. Regular additions ensure that the SM Knowledge Hub remains a valuable reference for construction professionals.

Technical Note TN-001 | When a Concrete Cube Fails
A failed concrete cube does not necessarily indicate poor concrete or an unsafe structure. This Technical Note explains the engineering response protocol, investigation checklist and evaluation process required before accepting or rejecting concrete based on cube test results. READ MORE
Technical Note TN-002 | Why Do Cube Strength Registers Rarely Show Extreme Results?
Concrete cube strength registers often show a surprisingly narrow range of compressive strength values. This Technical Note examines the engineering factors that influence recorded test data, explains why limited variation deserves investigation, and highlights the importance of transparent quality systems, reliable testing practices and sound engineering interpretation.
Technical Note TN-003 | Slump Loss During Transportation
Concrete leaves the RMC plant with the required slump but reaches site with reduced workability. This Technical Note explains the causes of slump loss during transportation, the investigation process and practical solutions before changing the mix or adding water.
Technical Note TN-004 | Cement–Admixture Compatibility
Learn how cement–admixture compatibility affects slump retention, setting time, water demand and concrete strength. This Technical Note provides a practical engineering approach to investigate compatibility issues, conduct laboratory and plant trials, identify root causes and implement preventive measures before changing cement or admixture in production.
Technical Note TN-005 | Segregation and Bleeding in Fresh Concrete
Segregation and bleeding are two of the most common fresh concrete problems observed during batching, transportation, placement and compaction. If not identified and controlled at the right stage, they can lead to non-uniform concrete, honeycombing, laitance, reduced durability and poor surface finish. This Technical Note explains the symptoms, root causes, investigation checklist and practical preventive measures to help engineers and site teams produce uniform, cohesive and durable concrete.
