Water Retainers (also known as water-retaining agents or admixtures) in the context of concrete and mortar, based on industry and technical literature.

This product is different from the commonly used cellulose, dextrin and other water-retaining viscosity products on the market, has good compatibility, and polycarboxylate superplasticizer can be mutually soluble, easy to use and can maintain long-term stability.

The product adsorbs excess water through high molecular structure and forms space interconnection mesh structure, which effectively improves the compatibility of concrete and reduces the sensitivity of polycarboxylate superplasticizer to concrete raw materials, water consumption and dosage.

This product can also solve the problem of sticky, bottom picking and poor fluidity of high grade commercial concrete.

Features:

1.Good water retention properties, can greatly improve the cohesion of concrete.

2.Low sensitivity and stability, perfect solution to the problem of mechanism sand concrete.

3.Mutually soluble with polycarboxylate superplasticizer, with high water solubility and adaptability.

4.It can effectively control water secretion, improve the ease and fluidity of concrete.

Application 

Water retainers are particularly valuable in situations where water loss is a major concern:

• Pumped Concrete: To maintain workability and prevent blockages during pumping .

• Ready-Mixed Concrete: To control slump loss during transport and placement, especially in hot weather .

• Self-Leveling and Repair Mortars: To ensure proper flow and adhesion on absorbent substrates.

• Concrete with Manufactured Sand: To compensate for the poor water retention and cohesiveness often caused by the irregular gradation and high fines content of manufactured sand .

Doping:

In the water reducing agent in the finished product dosage of 0.2%-1.5%, naphthalene aliphatic 0.1%-0.5% or less, according to the use of the requirements and application of the effect through the test to determine the dosage.

Packaging and storage matters:

1.The product is non-toxic, non-corrosive, no pollution to the environment, stored in a cool place.

2.This product is packed in 200KG plastic drums or transported by bulk tanker.

Water Retainer is an essential tool for controlling the rheology and hydration of cementitious systems. It prevents segregation, maintains workability, and ultimately contributes to the strength and durability of the hardened concrete or mortar. The choice of water retainer depends on the specific application, the type of binder, and the desired performance characteristics.
