Working mechanism of nano-SiO2 sol to alleviate the strength decline of oil well cement under high temperature by Chengwen Wang, Xin Chen, Wei Zhou, Yonghong Wang, Yucheng Xue, Faqiang Luo

“…The experimental results are summarized as follows: (1) The cement stone with 2% nano-SiO2 sol does not perform a strength reduction after cured for 5 days, and its XRD patterns indicate that low-dose nano-SiO2 sol will yield little effect on the cement hydration products; (2) While with a high dose, nano-SiO2 can react with calcium hydroxide, resulting in microstructure change of cement and the generation of a novel honeycomb calcium silicate hydrate gel (Ca/Si ratio is about 1.5); (3) Nano-SiO2 particles make the microstructure of cement stone more compact through impaction and filling into the pore among cement hydration products, which helps to prevent cement stone from strength retrogression under high temperatures. …”
