1.3 Chemical Properties

BDMA is highly alkaline and nucleophilic and can react with a variety of compounds. In bridge construction, BDMA is mainly used as a curing agent for epoxy resins, which can significantly improve the mechanical properties and chemical resistance of the resin.

2. Application of BDMA in Bridge Construction

2.1 Epoxy resin curing agent

Epoxy resin is a commonly used adhesive and coating in bridge construction, and its performance directly affects the structural stability of the bridge. As a curing agent for epoxy resin, BDMA can accelerate the curing process of the resin and improve its mechanical strength and durability.

2.1.1 Curing mechanism

BDMA forms a crosslinking network structure by opening the ring with the epoxy groups in the epoxy resin. This process not only improves the hardness of the resin, but also enhances its impact resistance and chemical resistance.

2.1.2 Application Example

On large bridgesAmong the steel structures and concrete structures, epoxy resin coatings are widely used for corrosion resistance and waterproofing. As a curing agent, BDMA can ensure the long-term stability of the coating in harsh environments.

2.2 Concrete Admixture

BDMA can also be used as an admixture for concrete to improve the working and mechanical properties of concrete.

2.2.1 Working performance

BDMA can reduce the viscosity of concrete and improve its fluidity, making it easier to pour and vibrate concrete. This is especially important for the complex structure of large bridges.

2.2.2 Mechanical Properties

BDMA improves the early and long-term strength of concrete by promoting cement hydration reactions. This is of great significance to the load-bearing capacity and durability of the bridge.

2.3 Preservatives

The bridge is exposed to natural environment for a long time and is susceptible to corrosion. As a preservative, BDMA can effectively delay the corrosion process of metal structures.

2.3.1 Anti-corrosion mechanism

BDMA slows down corrosion by forming a protective film with the metal surface, preventing oxygen and moisture from contacting the metal.

2.3.2 Application Example

In the steel structure and concrete steel bars of bridges, BDMA can significantly extend its service life as a preservative.

3. Key technologies of BDMA in structural stability

3.1 Epoxy resin curing technology

The curing process of epoxy resin directly affects the stability of the bridge structure. As a curing agent, the dosage and curing conditions of BDMA need to be precisely controlled.

3.1.1 Dosage control

The excessive or too little amount of BDMA will affect the performance of the epoxy resin. Generally, the amount of BDMA is 5-10% by weight of the epoxy resin.

Epoxy resin weight (kg) BDMA dosage (kg)

100 5-10

200 10-20

300 15-30

3.1.2 Curing conditions

The curing temperature and time of BDMA need to be adjusted according to the specific situation. Typically, the curing temperature is 20-30°C and the curing time is 24-48 hours.

Currecting temperature(°C) Currecting time (hours)

20 48

25 36

30 24

3.2 Concrete admixture technology

BDMA, as a concrete admixture, needs to be strictly controlled for its addition amount and stirring time.

3.2.1 Adding quantity control

The amount of BDMA added is usually 0.1-0.5% of the weight of concrete. Too much BDMA will cause the strength of concrete to decrease, and too little will not achieve the expected results.

Concrete weight (kg) BDMA addition amount (kg)

1000 1-5

2000 2-10

3000 3-15

3.2.2 Stirring time

The mixing time of BDMA needs to be adjusted according to the concrete formula and construction conditions. Typically, the stirring time is 5-10 minutes.

Concrete Formula Stirring time (min)

Ordinary Concrete 5-7

High-strength concrete 7-10

3.3 Anti-corrosion technology

BDMA, as a preservative, needs to be precisely controlled in its coating method and amount.

3.3.1 Coating method

BDMA can be applied to metal surfaces by spraying, brushing or dipping. Spraying is suitable for large-area coating, brushing is suitable for small-area coating, dip coating is suitable for complex structures.

Coating method Applicable scenarios

Spraying Large area coating

Brushing Small area coating

Dipping Complex Structural Coating

3.3.2 Coating volume control

The amount of coating of BDMA is usually 0.1-0.3 kg/m² of the metal surface area. Too much coating will lead to too thick coating, affecting the mechanical properties of the metal, and too little will not achieve anti-corrosion effect.

Metal surface area (m²) BDMA coating amount (kg)

100 10-30

200 20-60

300 30-90

4. Advantages of BDMA in Bridge Construction

BDMA, as a preservative, can effectively delay the corrosion process of metal structures and extend the service life of the bridge. This is especially important for bridges that are exposed to the natural environment for a long time.

4.3 Improve construction performance

BDMA, as a concrete admixture, can improve the working performance of concrete and make construction more convenient and fast. This is of great significance for the construction of complex structural tools of large bridges.

5. Challenges of BDMA in Bridge Construction

5.1 Environmental Impact

BDMA, as a chemical additive, may have certain impact on the environment during its production and use. Therefore, when using BDMA, corresponding environmental protection measures need to be taken to reduce its pollution to the environment.

5.2 Cost Control

BDMA is more costly in production, which may increase the overall cost of bridge construction. Therefore, when using BDMA, it is necessary to comprehensively consider its performance and cost and choose an economical and reasonable solution.

5.3 Technical difficulty
