· JVASP-104633· Ca3SiO

Ca₃SiO₅ (tricalcium silicate) is a calcium silicate ceramic compound and the primary phase in Portland cement clinker, responsible for the early strength development in concrete. It is widely used in civil infrastructure, construction, and cementitious materials where rapid hydration and early-age strength gain are critical performance requirements. This material is preferred over slower-hydrating phases when fast setting, high early strength, and infrastructure durability are needed.

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.
