The CF-S2 concrete waterproof densifier is a shrinkage-reducing densifying waterproofing agent. Through chemical reactions with cement hydration byproducts, it generates crystalline and gel substances that effectively fill micro-voids and capillary pathways in concrete, preventing water molecule penetration. It improves the workability and physical properties of concrete, enhancing project quality. The product also offers excellent water-reducing effects, improving the working state of concrete.
Implementation Standard: JC474-2008 "Waterproofing Agents for Mortar and Concrete"
Dosage: 0.2% of the total weight of cementitious materials in concrete
Performance Advantages:
Inorganic product, low dosage, easy dispersion, good water solubility; improves concrete gel density, compressive strength, crack resistance, and increases impermeability by more than 3 times compared to standard concrete. Effectively controls the formation of concrete cracks and self-repairs cracks below 0.4mm; significantly enhances concrete strength, controls early shrinkage, effectively reduces thermal stress, and minimizes the need for deformation joints and post-poured strips (suitable for ultra-long seamless construction techniques).
Scope of Application:
1. Widely used in underground waterproofing projects for industrial and civil buildings.
2. Suitable for waterproof and impermeable concrete projects such as subways, bridges, and tunnels.
3. Applicable for water towers, reservoirs, storage tanks, fire pools, wastewater treatment plants, and water conservancy and hydropower projects.
| 1. Ordinary impermeable concrete contains semi-closed pores and continuous pathways.
2. CF-S2 waterproof concrete is in a fully sealed state, forming a crystalline chain
that bonds firmly with the concrete, complementing each other, and exhibits excellent durability. |
