Expansion cement impermeable and waterproof

AEC expansion cement AEC expansive cement is a kind of hydraulic cementitious material with micro expansion to compensate the shrinkage of concrete. Its main hydration product is CSH gel, C _three A·3C aS O _four 32H20 (ettringite). 1. Good crack resistance; 2. Good impermeability; 3. Low alkali; 4. Low hydration heat; 5. High strength; 6. Good adhesion; 7. Good rust resistance; 8. Slight expansion and shrinkage

2、 Main uses of AEC expansive cement AEC expansive cement can not only prevent or greatly reduce the cracking of concrete soil and water, but also has excellent concrete performance and high strength. It is an ideal anti cracking and anti-seepage structural material to compensate shrinkage. Since the asphalt felt waterproof layer is omitted, the construction progress is greatly accelerated, and the materials and manpower are saved, it is used in various self waterproof and anti-seepage projects with better technical and economic effects. It is applicable to industrial and civil construction, basement engineering, * * *, highway tunnel lining, post pouring joint concrete, secondary grouting material, waterproof concrete for roof, floor, kitchen and bathroom, municipal engineering, and bridge engineering. 3、 Precautions for construction of AEC expansive cement The construction of AEC expansive cement is the same as that of ordinary cement, and attention should be paid to watering and curing during construction. For construction under normal temperature, the concrete can be watered for curing 2-4 hours after final setting, and the curing period is 7-14 days. Three Lions AEC expansive cement
