TPI RS-600C
Settling Inhibitor Chemicals for Roughening Concrete Joints

Roughen the surface of the construction joint.
The integrity and watertightness of concrete structures are two vital elements of any concrete structure. At these locations... construction stop – The junction between old and new concrete – if not properly treated, the structure will be prone to cracking, leaking, and a significantly reduced lifespan.
In modern construction, manual sanding has become outdated, costly, and does not guarantee uniformity. TPI RS-600C This is a groundbreaking solution that helps construction companies create ideal joint surfaces quickly, efficiently, and economically.
What is TPI RS-600C?
TPI RS-600C It is a water-based liquid chemical specifically designed to control the setting process of cement at the surface layer (approximately 3-5 mm) of fresh concrete.
When applied to the surface of a construction circuit, TPI RS-600C This will temporarily prevent the hydration of cement in this area. After a certain period, the inhibited cement layer will be easily washed away, exposing the underlying aggregate (stone/gravel), forming a layer. rough surface (exposed aggregate) perfect.
This rough surface is key to achieving the desired result. mechanical connection Ensure absolute separation between the freshly poured concrete layer and the subsequent new concrete layer, guaranteeing that the structure achieves the monolithic integrity as designed.
Outstanding Benefits of Using TPI RS-600C
TPI RS-600C It's not just a product, but an optimized process for handling construction site breaks:
1. Ensure Maximum Bond Strength
Creates a rough surface with controlled depth, significantly increasing the contact area and shear strength (Shear Strength) between concrete pours far surpasses that of manual chiseling methods.
2. Save Time & Labor Costs
Remove completely The processes of chiseling, scraping, and blowing away dust are costly. The treatment of construction joints is now simply a matter of spraying chemicals – waiting – rinsing, which shortens completion time and reduces labor costs.
3. Consistent Quality and Easy Control
Unlike hand-chiseling, which is prone to unevenness, TPI RS-600C This creates an exposed aggregate surface with a consistent depth across the entire construction joint, making it easier to control construction quality.
4. Safe and Clean Construction
This water-based product is non-toxic, does not generate dust or loud noise like demolition work, and contributes to a safer and more friendly working environment.
5. Diverse Applications
This product is ideal for all structures with construction joints, especially those requiring high monolithic integrity and waterproofing, such as: Foundations, basement walls, storage tanks, industrial floors, and hydroelectric dams…

Basic Installation Guide with TPI RS-600C
Instructions for use TPI RS-600C Very simple and easy to implement on site:
| Step | Work | Detailed Description |
| 1. Preparation
|
Sprayer
|
TPI RS 600C is a pre-mixed solution, to be used directly from its container. Do not dilute the product. |
| 2. Applications
|
TPI RS-600C Sprayer
|
Spray onto the horizontal surface of the concrete as soon as possible, after the initial water separation phase of the concrete has ended, but before the start of setting. Coverage: approximately 0.2 – 0.3 kg/m² (depending on the required depth). |
| 3. Ninh Ket
|
Waiting and Maintenance
|
The sprayed surface must be protected from sunlight.
Direct sunlight and hot winds can cause concrete surfaces to dry out quickly. Proper curing procedures are crucial to ensuring the durability and quality of the concrete. |
| 4. Completion
|
Wash away
|
After pouring the concrete for 8-10 hours (maximum 24 hours), use a low-pressure water hose or a brush (wire brush) to gently scrub away the inhibited cement paste layer, exposing the cleaned aggregate.
|


Note: Washing should be carried out within the optimal timeframe to ensure the desired aggregate exposure depth and to avoid affecting the strength of the core concrete.
