Introduction
Fosroc Chemicals India Private Limited, a leading manufacturer of construction chemicals, has introduced the Fosroc Auramix 350 DIS. This high-performance admixture is marketed and supplied in India by their authorized distributor, Space Arc Engineering, which offers the entire Fosroc range of products. In this article, we will discuss the uses and advantages of the Fosroc Auramix 350 DIS .

Product Description
The Fosroc Auramix 350 DIS is a high-range water-reducing and retarding admixture designed for a wide range of concrete grades. It is a high-performance super plasticizer that is suitable for both low and high-grade concrete applications.

Main Uses
The Fosroc Auramix 350 DIS is developed for several applications, including:

• Long workability retention concrete
• Pumpable concrete
• High-performance concrete

Advantages
The Fosroc Auramix 350 DIS offers numerous advantages:

1. It is a low viscosity admixture, suitable for pumping different grades of concrete to greater heights.
2. It is compatible with concrete having cement replacements and low water-cement ratios.
3. The admixture provides higher strength without increasing cement content or reducing workability, making it ideal for precast concrete production.
4. It reduces the rate of workability loss typically associated with super plasticizers, decreases shrinkage cracking due to lower water-cement ratios, and makes the concrete water-impermeable.
5. The product offers better resistance to carbonation.
6. It reduces shrinkage and creep.
7. It increases the durability of the concrete.

Standard Compliance
Fosroc Auramix 350 DIS complies with IS:9103:1999 as a water-reducing and retarding type admixture and ASTM C 494 Type F and G, depending on dosage.

Technical Specifications
The Fosroc Auramix 350 DIS is a light brown liquid with a minimum pH of 6.0 and a volumetric mass of 1.08 ± 0.02 kg/liter at 25°C. It is instantly dispersible in water and does not contain any chloride content as per IS:456 standards.
The admixture is based on a unique combination of new generation super plasticizers that use polycarboxylic ether polymer with long lateral chains. Its electrostatic dispersion mechanism considerably reduces water demand in flowable concrete.
Auramix 350 DIS effectively disperses cement particles in the concrete mix, exposing a larger surface area to the hydration process. This effect can be utilized to increase the strength of the concrete, produce high workability concrete, reduce cement content, or retard the setting time of the concrete.

Dosage Recommendations
The optimum dosage of Auramix 350 DIS should be determined by conducting laboratory and batch trials to meet specific requirements. However, the normal dosage range is between 0.3 to 1.3 percent by weight of the total cement or binder content.
In some cases, dosage beyond the limits may be used to meet particular mix requirements in consultation with Fosroc's technical department. Overdosing may cause a delay in setting and potential segregation.

Estimating and Packaging
Auramix 350 DIS is available in 200 kg, 250 kg, and bulk packaging options to suit various project needs.

Storage Conditions
The product has a minimum shelf life of 12 months, provided it is stored within a temperature range of 20°C to 50°C.

Precautions
Although Auramix 350 DIS does not fall into hazard classifications under current regulations, it should not be swallowed or allowed to come into contact with skin and eyes. Protective gloves and goggles should be worn when handling the product. Skin contact should be washed off with water, and in case of eye contact, rinse immediately with plenty of water and seek medical advice. If swallowed, seek medical attention immediately and do not induce vomiting.

Auramix 350 DIS is water-based and non-flammable.

Cleaning and Disposal :
Spillages should be absorbed onto sand, earth, or vermiculite and transferred to suitable containers. Remnants should be hosed down with large quantities of water. Excess or waste material disposal should comply with local legislation and be under the guidance of the local waste regulatory authority.
