Uses and applications of limestone powder
- Construction: filler in wall putty, tile adhesives, dry mortar and concrete products.
- Paints and plastics: low-cost white extender and filler.
- Glass and ceramics: source of calcium oxide in glass batches and ceramic bodies.
- Agriculture: liming material to raise the pH of acidic soils.
- Environment and industry: flue gas desulphurisation, water treatment and as a flux in metallurgy.

Frequently asked questions about Limestone Powder
What is limestone powder made of?
It is ground limestone rock, made up mainly of calcium carbonate (CaCO3) with small amounts of other minerals.
How is limestone powder different from calcite powder?
Calcite powder is usually ground from purer, whiter calcite crystals. Limestone powder comes from limestone rock and can vary more in whiteness.
Can it be used in agriculture?
Yes. Ground limestone is used to correct acidic soils. Dosage depends on soil testing.
Which fineness do you supply?
Fineness depends on the lot. We share the available sizes and test values with the quotation.
