Release time:
2024-10-11
1. Overview
Anti-seepage castable is a kind of building material used to prevent liquid leakage, which is widely used in water conservancy, electric power, construction and other engineering fields.
Main 2. criteria
1. Raw materials: use high-quality cement, aggregates, admixtures and additives and other raw materials to ensure that the quality of raw materials meet the standards.
2. Appearance: The impervious castable shall be a uniform mixture without defects such as agglomeration and inclusion.
3. Fluidity: It has good working performance, ensuring that it can be evenly filled during the pouring process, and it is not easy to produce voids.
4. Strength: according to different engineering requirements, its strength grade should meet the design requirements, through scientific mix design, to ensure that the compressive and flexural strength standards.
5. Durability: It has good impermeability and anti-aging properties, ensuring good performance during long-term use.
6. Environmental protection: in line with environmental standards, low pollution, low emissions.
3. specific parameters
1. Compressive strength: According to engineering requirements, it is generally C20, C25, C30, etc.
2. flexural strength: according to the engineering requirements, to meet the corresponding standards.
3. Permeability: according to the engineering requirements, to achieve the corresponding impermeability level.
Shrinkage: control within a certain range to avoid cracks.
5. Durability: After scientific test, it can meet the requirements of engineering service life.
6. Environmental protection indicators: in line with environmental standards, low noise, low pollution.
4. detection and evaluation
Periodic testing and evaluation of impervious castables, including raw material testing, production process monitoring, product performance testing, etc. Through scientific detection means, to ensure that each batch of impervious castable meet the standard requirements.
5. Summary
The standards for impervious castables cover raw materials, appearance, fluidity, strength, durability, environmental protection and safety. In the actual project, the construction and acceptance should be carried out in strict accordance with the standards to ensure the quality of the project. In addition, the inspection and evaluation of impervious castables are also important to ensure the stability of their performance and quality. The formulation and implementation of these standards will help to ensure the anti-seepage of water conservancy, electric power, construction and other projects, and improve the safety and service life of the project.
