Construction steps:

1. Preparation: Clean the construction area, ensure the ground is flat, and remove debris and dirt.

2. Basic treatment: Carry out basic treatment as needed, such as ground repair and strengthening, etc.

3. Construction template: According to the design requirements, build the construction template to ensure that the castables form the required shape and size.

4. Configure castables: According to relevant specifications and construction plans, prepare the required castables to ensure accurate mixing ratios.

5. Castable: Pour the castable into the template and use a vibrator to pour evenly to ensure that the material is fully filled and eliminate air bubbles.

6. Smoothing: Use tools such as a vibrator, scraper or comb to smooth the surface of the castable to ensure that there are no obvious marks or unevenness.

Maintenance precautions:

1. Curing period: Set the curing period according to the type and specification requirements of the castable, and perform appropriate maintenance on the castable.

2. Curing environment: Maintain the stability of the curing environment, such as temperature, humidity, etc., to avoid adverse effects on the castables.

3. Prevent damage: During the curing period, strengthen the protection of the castable to avoid damage to it by external forces or other objects.

4. Cleaning and maintenance: Clean the surface of the castable regularly to avoid the accumulation and adhesion of sediments, which will affect the appearance and function.

It is important to note that different types of castables may have different construction and maintenance requirements, and specific operations should be carried out according to the characteristics and specifications of the castables used. In addition, the quality of construction and maintenance plays an important role in the service life and performance of castables, and operations should be carried out in strict accordance with relevant standards and requirements.
