· JVASP-104162· H2C3S2O

H2C3S2O is a calcium silicate hydrate (CSH) ceramic compound, a key constituent phase found in hydrated Portland cement and cementitious materials. This material is primarily encountered as a research compound rather than a commercial product in its pure form, studied for understanding cement chemistry, durability mechanisms, and performance in concrete systems. Engineers work with CSH phases indirectly through cement-based composites, where this compound's formation and stability directly influence long-term strength development, chemical resistance, and service life in structural applications.

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.
