What properties should be tested for ash calcium powder? What tests are available?

Lime calcium powder, also known as calcium hydroxide powder or quicklime powder, is a fine powdered inorganic compound, the main component is calcium hydroxide (Ca(OH)2), usually white or off-white. Ash calcium powder has excellent alkalinity, can be used to neutralize acidic substances, can also be used as disinfection, anti-corrosion and desiccant and other purposes. In the field of building materials, ash calcium powder is often used as a raw material for adhesives, coatings, fillers, moisture-proof agents and other materials. Detection [...]
