摘要：
A mold additive suitable for use in a mold for continuous casting of steel which comprises, as its base material, at least 50% by weight of synthetic calcium silicate which contains CaO and SiO.sub.2 in a total amount not less than 70% by weight, and whose CaO/SiO.sub.2 ratio is not lower than 1.20. A mold additive of low bulk density and superior in heat insulation can be obtained and its CaO/SiO.sub.2 ratio can be widely adjusted.
