1. Dry Powders and Fine Aggregates
These form the base of most dry-mix mortars and are easily mixed by the single-shaft design:
Cementitious materials: Portland cement, white cement, slag cement, fly ash, and silica fume (used as binders or admixtures).
Lime products: Hydrated lime (for improving workability and plasticity).
Fine aggregates: Sand (river sand, quartz sand, or manufactured sand with particle sizes typically below 5mm), mica, and lightweight aggregates like perlite or vermiculite (for insulation mortars).
2. Additives and Chemicals
Single-shaft mixers ensure uniform dispersion of small-volume additives, which are critical for modifying mortar properties:
Chemical admixtures: Water reducers, retarders, accelerators, air-entraining agents, and superplasticizers (in powder or granular form).
Fibers: Polypropylene fibers, glass fibers, or steel fibers (short-length, for reinforcing mortar).
Fillers: Calcium carbonate, talc, or gypsum (to adjust density or cost).
3. Specialty Dry-Mix Mortars
The mixer is versatile enough to handle pre-mixed dry formulations for specific applications:
General construction mortars: Masonry mortar, plastering mortar, and floor leveling mortar.
Specialty mortars: Tile adhesive, thermal insulation mortar, repair mortar, waterproof mortar, and fire-resistant mortar.
Dry grouts: Cementitious grout for tile joints or structural filling.
4. Semi-Dry Materials
While primarily for dry mixes, it can also handle materials with minimal moisture (low liquidity) without clumping, such as:
Damp sand (with controlled moisture content to prevent caking).
Semi-dry binder mixtures (e.g., cement-sand blends with trace water for pre-casting applications).
