C2S
ceramic· JVASP-117940· C2S
C2S (dicalcium silicate) is a ceramic compound belonging to the silicate family, commonly encountered as a major phase in portland cement clinker and calcium silicate materials. It is widely used in construction and infrastructure applications, particularly in cement-based composites, concrete products, and specialized refractory materials where moderate strength and durability are required. Engineers select C2S-containing systems for cost-effectiveness and long-term performance in structural applications, though it develops strength more slowly than tricalcium silicate (C3S) and is preferred in applications where heat generation during hydration must be minimized.

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.
