Static blasting chemical reaction time

1 to 12 hours. According to Changsha Dongke Building Materials Technology Co., Ltd., the chemical reaction time is short, and the maximum expansion force can appear at 1 hour. The reaction time can be adjusted from 1 hour to 12 hour. There are two main construction methods of static blasting. The traditional construction method is to add water to some solids such as silicate and calcium oxide, stir them into solids, and then put them where they need to be filled to make them undergo hydration reaction. The solids become hard, the temperature rises, the volume expands, and the rocks are broken, which is called static blasting agent, expansion agent and crushing agent.
