纳米颗粒对超低水胶比复合水泥浆体水化和孔结构的影响
Influence of nano-particles on hydration and pore structure of compounded paste with very low water-binder ratio
摘要
Abstract
For the sake of understanding the effects of nanoparticles on hydration and microstructure of cement-based materials with very low water to binder ration,the chemically bound water and pore structure of cement paste with very low water-binder ratio incorporating four nanoparticles of nano-SiO2,nano-Al2O3,nano-Fe2O3 and nano-CaCO3 were investigated by TG and BET experimental methods,respectively.Results show that the incorporation of aforemen-tioned nano-particles plays more significant role in promoting the hydration process of paste with very low water to binder ratio as compared to the ordinary cement paste.Due to the nano-scale filling role,the porosity and average pore diame-ter of samples can be reduced by adding nanoparticles.It proves obvious advantage in preparing high performance cement-based materials with very low water to binder ratio by utilizing nanoparticles.关键词
