Effect of C-S-H Nucleating Agent on Cement Hydration

This work aims to study the effect of a nucleating agent on cement hydration. Firstly, C-S-H crystal nucleation early strength (CNA) is prepared. Then, effects CNA hydration mechanism, enhancement effect, content, 28-days degree and fractal dimension products are studied by kinetics calculation, resistivity test, BET specific surface area test quantitative analysis backscattered electron (BSE) images, respectively. The results show that significantly improves mixture, which better than triethanolamine (TEA). shortens beginning time induction period 49.3 min end acceleration 105.1 blank sample. increases products, while TEA decreases dimension. mortars; 1-day 3-days mortars with more 7-days These will provide reference for practical application agent.
