How to process cement to make it waterproof
In the field of construction and decoration, the waterproof treatment of cement is an important issue. With the advancement of science and technology, cement waterproofing technology is also constantly updated. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce in detail the methods, materials and precautions for cement waterproofing processing.
1. The importance of cement waterproofing
Cement itself does not have waterproof properties, but in practical applications, waterproofing requirements are very common. For example, in basements, bathrooms, swimming pools and other places, if the cement is not waterproof, it can easily lead to leakage problems and affect the safety and service life of the building structure.
2. Main methods of cement waterproofing processing
The following are several common cement waterproofing processing methods:
| method | Principle | Applicable scenarios |
|---|---|---|
| Add waterproofing agent | Add waterproofing agent during the cement mixing process to change the pore structure of the cement | Large area construction such as walls and floors |
| Use waterproof coating | Apply waterproof coating on the cement surface to form a waterproof layer | Humid environments such as bathrooms and kitchens |
| Osmotic crystallization | Waterproof crystals formed inside the cement through chemical reactions | Basements, bridges and other parts subject to long-term water pressure |
| Polymer modification | Adding polymers to cement to improve its waterproof properties | High-demand waterproofing projects |
3. Recommendations for popular waterproof materials
According to the Internet hot data in the past 10 days, the following waterproof materials have attracted much attention:
| Material name | Features | price range |
|---|---|---|
| Cement-based penetrating crystalline waterproof coating | Good waterproof effect and long service life | 50-80 yuan/kg |
| Polymer cement waterproof coating | Good elasticity and strong crack resistance | 30-60 yuan/kg |
| Silicate waterproofing agent | Mixed with cement for easy construction | 15-30 yuan/kg |
| Polyurethane waterproof coating | Strong weather resistance, suitable for outdoor use | 80-120 yuan/kg |
4. Precautions for cement waterproofing construction
1.Basic treatment: Make sure the cement base is smooth, clean, and free of oil stains and loose particles.
2.Material ratio: Strictly follow the instructions to avoid excess or deficiency.
3.construction environment: Temperature 5-35℃, humidity not exceeding 85%.
4.Maintenance time: The waterproof layer needs to be maintained for 24-48 hours after construction.
5.Quality inspection: The waterproof effect can be tested through closed water test.
5. Latest technology trends
1.Nanotechnology Applications: Nanomaterials can significantly improve the waterproof performance of cement.
2.self-healing waterproof: New material can automatically repair cracks when they appear.
3.Environmentally friendly and waterproof: Water-based waterproof materials have become the new favorite in the industry.
6. Frequently Asked Questions
Q: How many years can waterproof cement be used?
A: High-quality waterproofing treatment can usually guarantee waterproofing effect for 10-15 years.
Q: How long after waterproof cement construction can it be exposed to water?
A: Generally, it requires 24-48 hours of maintenance. The specific time depends on the product description.
Q: How much higher is the price of waterproof cement than ordinary cement?
A: Depending on the waterproofing process, the cost will increase by 20%-50%.
7. Summary
Cement waterproofing processing requires the selection of appropriate methods and materials according to specific scenarios. With the advancement of technology, the performance and construction convenience of waterproof cement are constantly improving. During the construction process, strict compliance with specifications is the key to ensuring waterproofing effect.
Through the above introduction, I believe everyone has a more comprehensive understanding of cement waterproofing processing. In practical applications, it is recommended to consult a professional waterproofing engineer to obtain the best waterproofing solution.
