Ground Calcium Carbonate20

Calcite Sand 20 Mesh

20 Mesh Calcite Sand is a versatile medium-coarse calcite granular material, bridging the performance gap between coarse 10 mesh and fine 40-80 mesh calcite sand. It balances structural hardness and decorative fineness, with uniform particle size, extremely low fine powder content and excellent adhesion performance. Supporting full-index customization, it is widely used in architectural decoration, artificial stone processing, construction mortar and industrial filling industries, with outstandi

Product Performance & Advantages

20 mesh calcite sand is processed through fine crushing and multi-layer precise screening, with pass rate up to 99%-99.995% and zero irregular particles. Compared with 10 mesh coarse sand, it has finer granularity and better surface flatness for decorative products; compared with fine mesh sand, it has higher hardness and stronger structural stability. It features ultra-low moisture, stable chemical performance, excellent weather resistance and bonding compatibility with cement, resin and polymer materials. It can effectively improve the compactness, wear resistance and decorative effect of finished products.

Application Scope

Widely used in terrazzo flooring production, artificial stone and cultural stone processing, building mortar and waterproof coating aggregate. In industrial fields, it is suitable for wear-resistant industrial flooring, landscape decorative sand paving and water treatment filtration. It also serves as granular filler for rubber and plastic products, with wide applicability in construction and light industrial decoration.

Frequently Asked Questions

What is the difference between your calcium carbonate powder and calcite sand?

Calcium carbonate powder (GCC) covers 325–2500 mesh for filler and coating use. Calcite sand is a coarse granular product (10, 20 and 40–80 mesh) used as decorative aggregate for terrazzo, artificial stone, mortar and industrial flooring.

What CaCO₃ content and whiteness can you achieve?

CaCO₃ ranges from 88% to 98% for standard grades and 20%–97% for customised grades; whiteness ranges from 75 to 97. Batch test reports are issued for every shipment.

Do you supply food-grade or cosmetic-grade calcium carbonate?

Our 2500 mesh ultra-fine grade with CaCO₃ ≥ 96% and whiteness 93 is used as a cosmetic and food-grade auxiliary filler. Dust-proof professional packaging and OEM labelling are available.

How is the powder packed and shipped?

Standard packing is 25 kg or 50 kg woven bags, paper-plastic composite bags, kraft paper bags and 1000 kg / 1250 kg tonne bags. We load 25–27 tonnes per 20 ft container and ship from Dalian or Yingkou port.
