Product Description

ST-01Z reinforcement corrosion inhibitors for concrete is a kind of admixture which is added to concrete to prevent or slow down the corrosion of steel bar, and to improve the durability of reinforced concrete. Passivation film and adsorption film can be formed on the surface of the reinforcing steel bar, the whole steel bar is covered by a layer of oxide passivation film. Compactness is very good, Long term effective inhibition of the electrochemical reaction of steel corrosio, dense protective layer formed on the surface of reinforcing steel bar. When the harmful ions such as Cl -) invasion in concrete structures, which can effectively inhibit, stop and retard the corrosion electrochemical reaction process, so as to extend the service life of reinforced concrete structures, so as to prolong the service life of the reinforced concrete.

Range of application:

This product is mainly used in chloride based corrosive environment, such as bridge, marine engineering and coastal engineering which easily are damaged by desalted water and snow melting agent, using sea sand as concrete sand, chloride salt of construction water is beyond the standard requirements, or using low alkali cement, or reinforced concrete and Embedded parts with low alkali parameter. Or repair and reinforcement of steel products need to strengthen the protection of concrete occasions, corrosion of reinforced concrete structures, etc.

Attention:

1,Generally use the dry mixing method, also soluble in water mixing (including some insoluble). Be sure to stir evenly, can be appropriate to extend the mixing time. This product is slightly water reducing, suitable water reduction under the condition of keeping the original flow degree

2,When used in combination with other additives, concrete test should be done to determine its adaptability firstly; do not use air-entraining water reducing agent, noted first add this product, after the product and cement were uniformly mixed, then add other additive.

3, special corrosion conditions, in addition to the use of stainless steel rust inhibitor, but also should take other protective measure

4,All of the materials which are made up for concrete should meet the requirements of <Building gravel, crushed stone >GB / T14685-2001 and< building sand >GB / T14684-2001.

Packaging & Shipping

1.packing: 50kg/ 25kg per PP bag.

2.Storing: Should be stored in a cool and dry ventilated warehouse, away from the inflammable and explosive materials, shelf life of one year, if there is a slight absorption of the phenomenon, this product can be dissolved in water to use.
