Lubricant and concrete water reducer with retarding mode of concrete
In the definition of water-reducing concrete additive, lubricant refers to a substance that significantly reduces the amount of water in the mixture without changing the fluidity, or increases the amount of slump water or fluidity significantly, or both effects. creates at the same time. LR80 is a lubricant and water reducer based on calcium lignosulfonate and polynaphthalene sulfonate as a substance that reduces and increases the efficiency of concrete, it has the ability to increase the working time in the paste state and provides the possibility of creating a little retarding property. It is suitable for concretes with a ratio of water to cement above 45% and hot air, with high spreading of cement, it makes the final concrete uniform. This additive complies with ASTM C494 and 2930 ISIRI and ASTM C1017 standards.
Physical and chemical state:
Properties and effects:
– Increase slump or efficiency of concrete – Reducing the water-cement ratio of concrete by about 5% to 12% and improving the final strength of concrete. – Improves cohesion and uniformity of concrete. – Increasing the density of concrete and thus increasing the durability of concrete. – Improvement of concrete sealing in high consumption ranges. – Increasing the time of primary and secondary setting of concrete. – Ease of pumping
It can be mixed with a small part of concrete mixing water and added to concrete. It can be added to the ready mix of concrete and concreting can be done after complete mixing. This material can be added during batching or to ready concrete in the mixer.
The consumption range of this product is between 1 and 1.5% per kilogram of cement materials, including Portland cement (PC), fly ash (PFA), slag cement (GGBFS) and microsilica. The optimal amount of this product is determined by trial and error. Using too much of normal will cause the concrete to set, which is more severe for type 2 and 4 anti-sulfate cements. This additive can be used with other Grana Concrete products, but each additive must be added to concrete separately and should not be mixed together before use
– Types of concreting in hot weather. – Prefabricated parts. – Production of high quality mortars. – Making reinforced and non-reinforced concretes at normal and hot temperatures. -Increasing efficiency and maintaining service life in ready-mixed concrete. – Concreting beams, slabs, bridge decks, columns, shear walls.
The desired product is offered in 20, 200 and 1100 kg gallons.
The above product can be stored for one year under standard storage conditions.
This product is not dangerous, but when using it, be sure to use appropriate gloves, glasses, and masks to prevent allergic reactions.
Note: consumption less and more than the permitted range of this additive or the simultaneous consumption of multiple concrete additives must be done with the permission of the experts of the technical department of Granabtan Chemical Industries Company.
