摘要
This invention relates to an enhanced blended cement composition and to enhanced strength portland cements containing at least 4% C4AF when mixed with up to 0.2% of a higher trialkanolamine to exhibit a marked increase in 7 and 28-day compressive strengths. The higher trialkanolamine strength enhancing additive may be admixed with the cement powder or may be interground with the cement clinker during finish milling.
