Nano-sized calcium silicate hydrate (CSH) is an efficient nucleating agent for Portland cement, which can improve the early strength. In this paper, CSH/citric acid nanocomposites were prepared via nucleation and growth isolation with citric acid as a dispersion stabilizer at different citric acid concentrations. Effect of citric acid dosage on the structure and particle size distribution of CSH/citric acid nanocomposites (nano-CCNs) as well as the properties of Portland cement was investigated. The results show that citric acid can intercalate on the CSH, and the average particle size of nano-CCNs is between 90-160 nm. The higher the content of citric acid in nano-CCNs, the smaller the particle size and the more citric acid released in the alkaline solution at pH=13. Nano-CCNs accelerates the cement hydration, modifies the pore structure and increases the compressive strength of the cement (12 h, 1 d, 3 d, 7 d, 28 d) due to the synergy between the nanocrystal nucleus and citric acid released from the CCNs.

纳米水化硅酸钙(CSH)是硅酸盐水泥的高效早强晶核剂。以柠檬酸为分散稳定剂,采用成核晶化隔离法合成CSH/柠檬酸纳米复合物,研究了柠檬酸用量对CSH/柠檬酸纳米复合物(CCNs)结构、粒度分布的影响以及CCNs对水泥水化硬化的作用机理。结果表明:柠檬酸可插层进入纳米CSH层间,CCNs的平均粒径在90~160 nm之间,且CCNs中柠檬酸含量越高,其粒径越小,在pH=13的碱性溶液中释放出的柠檬酸越多。CCNs由于自身晶核及柠檬酸的协同作用影响水泥水化,改善了孔结构并提高了12 h、1 d、3 d、7 d及28 d抗压强度。

纳米水化硅酸钙(CSH)是硅酸盐水泥的高效早强晶核剂。以柠檬酸为分散稳定剂,采用成核晶化隔离法合成CSH/柠檬酸纳米复合物,研究了柠檬酸用量对CSH/柠檬酸纳米复合物(CCNs)结构、粒度分布的影响以及CCNs对水泥水化硬化的作用机理。结果表明:柠檬酸可插层进入纳米CSH层间,CCNs的平均粒径在90~160 nm之间,且CCNs中柠檬酸含量越高,其粒径越小,在pH=13的碱性溶液中释放出的柠檬酸越多。CCNs由于自身晶核及柠檬酸的协同作用影响水泥水化,改善了孔结构并提高了12 h、1 d、3 d、7 d及28 d抗压强度。

Nano-sized calcium silicate hydrate (CSH) is an efficient nucleating agent for Portland cement, which can improve the early strength. In this paper, CSH/citric acid nanocomposites were prepared via nucleation and growth isolation with citric acid as a dispersion stabilizer at different citric acid concentrations. Effect of citric acid dosage on the structure and particle size distribution of CSH/citric acid nanocomposites (nano-CCNs) as well as the properties of Portland cement was investigated. The results show that citric acid can intercalate on the CSH, and the average particle size of nano-CCNs is between 90-160 nm. The higher the content of citric acid in nano-CCNs, the smaller the particle size and the more citric acid released in the alkaline solution at pH=13. Nano-CCNs accelerates the cement hydration, modifies the pore structure and increases the compressive strength of the cement (12 h, 1 d, 3 d, 7 d, 28 d) due to the synergy between the nanocrystal nucleus and citric acid released from the CCNs.
