As concrete projects become more and more adaptable to various construction requirements such as urban construction, large bridges, high-speed rail construction, and underwater construction, new concrete building materials and new construction techniques are emerging one after another. Currently, in rapid road repairs, tunnel construction, and coal mine cementing materials, amorphous calcium aluminate can be used calmly and perform exceptionally well in meeting engineering requirements.
Under these emerging construction conditions and construction requirements, the requirements for new materials are getting higher and higher. In the above-mentioned practical applications, the requirements for concrete materials are very high, mainly in the following aspects:
1. Rapid setting
2. Early strength, high strength and high toughness
3. Good adaptability and compatibility with various materials
4. Low shrinkage
5. High strength in the later stage
6. Good anti-freeze performance
7. Good underwater performance
8. High durability
The above requirements coincide with the excellent properties of amorphous calcium aluminate, so adding amorphous calcium aluminate into concrete materials has become an indispensable part of concrete materials. In addition, through research and practice, the current adaptability of amorphous calcium aluminate and water reducing agent is as follows:
1. Compatibility between amorphous calcium aluminate and polycarboxylate superplasticizer: very good
2. Compatibility between amorphous calcium aluminate and naphthalene series superplasticizer: very good
3. Compatibility between amorphous calcium aluminate and calcium lignosulfonate: poor
