2 Material terms
Magnesium oxychloride concrete2.1
A composite material formed by mixing and hardening with a net paste as the base material and adding an appropriate amount of filler. Net paste

Its main component is active magnesium oxide.
2.4 Magnesium chloride (also known as brine) Magnesium chloride is a kind of blending agent, and its main component is magnesium chloride containing crystal water. According to its physical state, it can be divided into brine flakes, brine powder, brine blocks, brine, etc. The magnesium chloride solution made by neutralization reaction of hydrochloric acid and magnesia powder is called synthetic brine. 2.5 Wood chip
