260 retarder super

توضیحات

260 retarder super lubricant Physical state:

Description:

Certain long-lasting values are a suitable option for producing and transporting concrete over long distances, as well as long-term concreting and concreting in tropical areas. This additive is a concrete super-lubricant based on polycarboxylate ether, which delays the initial setting of concrete. This super-lubricant is suitable for concrete with a water-cement ratio of less than 40. CR260, with its high spreadability of cement, makes the final concrete uniform in hot weather.

Physical characteristics:

Physical state: honey liquid Density: 1.13 gr/cm at 20 degrees Celsius Increase in air percentage: less than 02/02 in the range of normal consumption The amount of alkaline substances: less than 5 grams equivalent to Na2O per liter of additive Freezing temperature: about -2 degrees Celsius Chlorine content: within the standard range

Properties and effects:

– Increasing the strength and slump of concrete with a certain amount of water to cement (w/c). – Correctly reducing the amount of water to cement (w/c) of concrete by about 20 to 30% – Ability to increase slump from 2 to 23 – The ability to maintain concrete slump for 130 minutes at 25 degrees Celsius -Reducing the permeability of concrete against water, chlorine and sulfate ions – No need for vibration

packaging method:

The desired product is offered in 20,200,1100 kg gallons.

Maintenance:

The above product can be stored for one year under standard storage conditions

instructions:

When we want to make concrete, we add the calculated amount of additive to the concrete along with mixing water and continue mixing for 3 to 5 minutes. It can be added to the ready concrete and then concreting. Note: Do not add the above additive directly to the dry cement and reduce the amount of the additive from the concrete water.

Scope of use:

The consumption range of this product is between 0.4 and 0.8% per kilogram of cement materials, including Portland (PC), fly ash (PFA), slag cement (GGBFS) and microsilica. It is not possible to use the above product outside the range. And the use above the range causes delay in concrete and does not lead to higher performance. Therefore, each additive should be used separately and should not be mixed together

Note: The use of less and more than the permitted range of this additive or the simultaneous use of several concrete additives must be done with the permission of the experts of the technical

Application:

Concreting in hot weather -Concreting in narrow and reinforced sections – Making concrete with high density – Making powerful and strong concretes – Long time between making and unloading concrete in hot weather

Safety items:

This product is not dangerous, but when using it, gloves, glasses and mask should be used to prevent allergic reactions. If an additive is splashed into the eye, the eye should be washed with clean water for 15 minutes. If the clothing is contaminated, it should be washed with detergent.
