ceramic· JVASP-124888· C3S
C3S (tricalcium silicate, 3CaO·SiO₂) is a calcium silicate ceramic compound and the primary active phase in Portland cement clinker. It hydrates to form the calcium silicate hydrate (C-S-H) gel that provides much of the early strength development and long-term durability in Portland cement-based binders. This material is fundamental to concrete production and is notable for its rapid early hydration kinetics and strength gain, making it the predominant driver of concrete performance in the first weeks of curing.

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.
