Applications of Hydrophobic Agents and Wood Fibers in Dry-Mix Mortar
1. Hydrophobic powder, dosage: 0.2–0.3%
Material definition:
Silane-based polymers
Main varieties:
1. Metal salts of fatty acids
2. Hydrophobic adhesive powder – hydrophobic/repellent
II. Crack-resistant fibers, dosage: 0.2–0.5%
Material definition:
A novel crack-resistant fiber for concrete and mortar, compounded primarily from polystyrene and polyester, is referred to as the “secondary reinforcement” of concrete.
Main varieties:
1. Alkali-resistant glass fiber
2. Vinylon fiber (PVA fiber)
3. Polypropylene fiber (PP fiber)
4. Acrylic fiber (PAN fiber)
Characteristics and Uses:
1. Crack Resistance and Toughening
2. Impact Resistance
3. Freeze-thaw resistance
3. Wood fiber, dosage: 0.2–0.5%
Material definition:
Natural fibers insoluble in water and organic solvents / Exhibiting excellent flexibility and dispersibility
Main varieties:
Wood fiber length typically ranges from 40 to 1,000 μm and can be used in dry-mix mortar.
Characteristics and Uses:
1. Crack resistance
2. Enhance
3. Anti-sagging
