Preparation of Nano-Particles Reinforced Cement Paste Based on Response Surface Method

Abstract

Abstract: Based on the response surface method, considering the three key influencing factors of nano-particles content (NPC), polycarboxylates superplasticizer content (PSC), and water-binder ratio (WBR), the response was based on the compressive strength of hardened cement paste. Using the central composite design method to design experiments, the strength models of nano-SiO₂, nano-CaCO₃, and nano-Al₂O₃ reinforced cement paste were established. The nano-CaCO₃ reinforced cement paste strength model was taked as an example to analyze the influences of various factors on the strength and verify the strength model. The results show that when the mass ratio of nano-particle to cement is 0.027 0, the mass ratio of polycarboxylates superplasticizer to cement is 0.017 5, and water-binder ratio is 0.25, the three nano-particles reinforced cement pastes have higher strength. The strength models of nano-SiO₂, nano-CaCO₃, nano-Al₂O₃ reinforced cement paste have high accuracy and reliability. The compressive strength response value of nano-CaCO₃ reinforced cement paste first increases and then decreases with the increase of NPC and PSC, and gradually decreases with the increase of WBR.

Key words: nano-particle, cement paste, preparation, strength model, response surface method, central composite design method
