Comparison: HCSA vs Traditional Expansive Mortar
| Description | Expansive Mortar (Extra Strength) | Traditional Expansive Mortar |
|---|---|---|
| Production Process | Large rotary kiln calcination at 1450°C, fully automated computer-controlled production | Small shaft kiln calcination at 700-800°C, simple batch mixing process |
| Appearance | Black fine powder | White coarse powder |
| Price | Relatively higher, suitable for projects requiring comprehensive cost-performance consideration | Very low unit price, but higher long-term maintenance cost |
| Expansion Stability | Balanced in all seasons, early and late stages maintain continuous compensating shrinkage | Strong early expansion but unstable later stage performance, seasonal variation |
| Alkali Content | Low alkali, corrosion-resistant, protective of steel reinforcement | High alkali, long-term risk of ASR and reinforcement corrosion |
| Suitable Projects | Basements, tunnels, water tanks, high-strength pumped concrete, municipal infrastructure, long-term waterproofing | Rural floors, short-term repairs, temporary small structures |
| Inspection & Acceptance | Stable batch quality, third-party testing pass rate high | Unstable batch quality, difficult to pass large project inspections |
| Construction Adaptability | Excellent pumpability, good compatibility with admixtures | Great pumpability, prone to segregation and bleeding |
Safety Cautions & Operating Procedure
Important Safety Guidelines:
- Maintain hole spacing between 30-60 cm when using rock expansive cracking agent
- Thoroughly clean holes with an air blow gun before filling with expansive slurry to remove dust and debris
- Workers must wear protective goggles and rubber gloves during pouring operations
- Control drilling depth within 90% of total material depth (optimal range: ~70%), never drill through. Maintain 10-15 cm of rock/concrete at bottom
- Ensure a free surface (open face) is available in the breaking direction for safe and effective operation
- Clean holes again using an air blow gun before filling with expansive slurry
- Avoid positioning heads directly above holes during filling to prevent gas or slurry ejection
- In case of skin or eye contact, rinse immediately with clean water and seek medical attention
- Fill slurry evenly to about 15 cm below hole mouth, stir to eliminate air pockets, then seal and cover with straw mats
- Personnel should not remain on-site for at least three hours after filling. Maintain safe distance if presence is necessary
- Thoroughly wash all exposed skin after operation completion to prevent irritation
