· JVASP-98767· Ca6Si3H2O13

Ca6Si3H2O13 is a calcium silicate hydrate ceramic compound, likely a member of the tobermorite or related calcium-silicate-hydrate (C-S-H) family that forms during cement hydration and concrete curing. This material is primarily encountered in research contexts focused on understanding cement chemistry and concrete durability, rather than as a standalone engineered ceramic for direct industrial application. Engineers encounter this phase as a fundamental constituent of hydrated Portland cement systems, where it influences long-term strength development, dimensional stability, and chemical durability—making it relevant to those optimizing concrete formulations, designing durable infrastructure, or investigating cement degradation mechanisms.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
