Formulation design of the multi-component cement additive by using engineering statistics

A novel methodology for the formulation design of the multi-component cement additive for the low early strength blend cement was presented by using engineering statistics. Components of cement additive such as triethanolamine, chloride, saccharide and a kind of divalent alcohol were simultaneously tested according to the arrangement of response surface methodology. Mathematical models were established to express the quantitative relationship between the chemical components of cement additive and the compressive strength of treated blend cement. The effectiveness and the possible interactions of these four chemicals contributing to the strength development of blend cement were further explored by the pareto chart and the contour plot. Finally according the performance analysis of four chemicals, the optimized formulations were brought forward and were validated in practical trials by Turkey's multiple comparison.
