Abstract Calcium silicate hydrate (C-S-H) and calcium hydroxide (CH, portlandite) are the dominant hydration products of Portland cement. However, the anisotropic layered CH and uncoordinated nucleation of C-S-H and CH severely restrict the macroscopic performance of cementitious materials. Here, we report a hydrogen-bond-regulated proton transfer strategy to mechanochemically synthesize a positively charged, isotropic disordered CH precursor (CHP_H+).

2. Results and Discussion 2.1. Single-Factor Experiment on the Preparation of LFM by Lactase Hydrolysis Figure 1a–c shows the effect of hydrolysis temperature, lactase addition, and hydrolysis time on lactose hydrolysis rate, respectively. As shown in Figure 1a, the lactose hydrolysis rate was the highest at the hydrolysis temperature of 37 °C, which was 78.97%; the lactose hydrolysis rate decreased to 65.17% at 41 °C, which showed that the lactase activity was greatly affected by temperature.
