Slag Cement

Slag cement requires nearly 90% less energy to produce than portland cement. According to the Slag Cement Association, substituting 50% slag cement for portland cement reduces greenhouse gas emissions by more than 40% and lowers the embodied energy of concrete by more than 30%. Another factor is slag cement's nearly white color.
