Cement, Construction & Infrastructure Materials
🏗️
Cement Clinker & Hydration Products
Detailed examination of clinker phases (C3S, C2S, C3A, C4AF), belite polymorphism, free lime, periclase, and hydration products (C-S-H, CH, ettringite, AFm) — microstructure, crystal morphology, and degree of hydration assessment.
🧱
Concrete & Mortar Microstructure
Porosity, air void distribution, ITZ (interfacial transition zone), aggregate-paste bonding, microcracking, carbonation depth, and ASR gel identification — critical for durability and performance evaluation of structural concrete.
🔍
Additives & Admixtures Analysis
Dispersion and effectiveness of fly ash, slag, silica fume, metakaolin, superplasticizers, air-entraining agents, and expansive agents — particle size, morphology, reactivity, and interaction with cement phases.
🛡️
Durability & Degradation Studies
Sulfate attack, chloride ingress, carbonation, alkali-silica reaction (ASR), delayed ettringite formation (DEF), freeze-thaw damage, and corrosion products in reinforced concrete — root cause analysis with photographic documentation.
🪨
Aggregates & Raw Materials
Petrographic analysis of fine & coarse aggregates, limestone, clay, gypsum, pozzolans — mineral composition, deleterious materials (reactive silica, clay lumps, organic impurities), shape, texture, and alkali-aggregate reactivity potential.
📉
Failure Analysis & Quality Control
Investigation of cracks, spalling, efflorescence, low strength, premature deterioration in buildings, bridges, dams, roads, and precast elements — supported by polished sections, thin sections, SEM/EDS when required, and standards-compliant reporting (IS, ASTM, BS).
