Abstract: To investigate the dispersing effect of nano-Fe2O3 in three kinds of commonly used superplasticizer solutions, these solutions were prepared. The effects of design parameters including nano-Fe2O3 content(NFC), polycarboxylate superplasticizer content(PSC) and the water-binder ratio(WBR) on compressive strength were evaluated based on the response surface orthogonal rotation combination design and using. Sequentially, the response surface between cement hardened paste design parameters and compressive strength was considered. The test result manifested that the dispersion effect of nano-Fe2O3 in polycarboxylate superplasticizer liquor solution was best. When NFC is 0.027, PSC is 0.017 5, WBR is 0.28, cement hardened paste can show favorable construction condition. The reliability and accuracy of response surface of nano-Fe2O3 cement-based composite can be verified in terms of statistics and application. Compressive strength increased up and then decreased with the increasing of PSC, decreased with the increa-sing of WBR, and increased with the increasing of NFC that suggested there was an optimum value generating the cement-based composite constructed favorable with superior compressive strength. RSM had a promising prospect to be widely used in the field of research and development on the new cement-based composite.
