利用Box-Behnken实验设计研究化学外加剂组分对水泥砂浆强度的影响
Influences of chemical additive components on strength of cement mortar by Box-Behnken design
摘要
Abstract
Influences of four components of cement chemical additive, triethanolamine, chloride, reductive saccharide and alcohol, on the strength development of mortar were investigated by Box-Behnken design (BBD).The quadratic equations for the correlation were obtained between dosages of chemicals and the strength of mortar, and the orders of effectiveness of chemicals were validated in pareto charts with contour plots to illustrate chemicals and their interactions for the strength enhancement of mortar.Results showed triethanolamine dominated the strength enhancement of mortar in the first 3 d curing, however its effect was weaker than that of chloride in 28 d.The effects of reductive saccharide only appeared in the first 3 d and the interaction effects of alcohol with triethanolamine and chloride enhanced the strength of cement mortar in 28 d.关键词
