What is the dosage of rust inhibitor for concrete with reinforced steel bars? Beijing rust inhibitor manufacturer and Tianjin concrete rust inhibitor

Product Features

1. This product can be mixed into concrete to prevent or delay the corrosion of steel bars, thereby extending the structure Lifespan, in the ** classification, is "incorporated" (DCI).

2. This product is suitable for concrete prepared with ordinary silica and slag cement. It is effective for fly ash, slag powder, silica fume and commonly used water reducing agents. Good compatibility.

3. This product is selective for air-entraining agents.

4. When used above 25℃, it will have obvious early strength and coagulation-promoting effects, and will have an impact on slump loss. If necessary, slowdown can be adopted. coagulation measures.

5. This product forms a dense protective layer on the surface of steel bars. When harmful ions (such as CL) invade the concrete structure, it can effectively sterilize and prevent And delay the electrochemical reaction process of steel corrosion, thereby extending the service life of reinforced concrete structures.

Instructions for use:

1. The recommended dosage is:

(1) In general industrial and civil buildings, bridges and other slightly corrosive environments, the recommended dosage is 4~8kg/m3.

(2) In severely corrosive environments such as harbor projects and coastal buildings, the recommended dosage is 8~12kg/m3.

2 , add this product, cement, and aggregate into the mixer at the same time for dry mixing. After mixing evenly, add water for mixing, and appropriately extend the mixing time to ensure that the concrete is mixed evenly.

3. When used in combination with other admixtures, a concrete trial mix should be done first to determine its adaptability; air-entraining water-reducing agents must not be used. The raw materials used in preparing concrete should comply with "Pebbles and Gravel for Construction" GB /T14685-2001 and "Construction Sand" GB/T14684-2001.
