Introduction
Fosroc Chemicals India Private Limited manufactures a wide range of construction chemicals, and Fosroc Auracast 50 is one of their most prominent admixtures. Space Arc Engineering, an authorized distributor, markets and supplies the Fosroc range of products in India. This article will discuss the uses and advantages of Fosroc Auracast 50 in detail, focusing on its unique features and applications.

What is Fosroc Auracast 50 ?
Fosroc Auracast 50 is a high - performance precast superplasticizer that enables the production of consistent concrete properties at the required dosage . It's a unique combination of the latest generation superplasticizers based on polycarboxylic ether polymer with long side chains and short main chains .

Unique Features
Cement dispersion is substantially enhanced, and the hydration process can begin rapidly, thanks to this mixture. The electrostatic dispersion that happens at the start of the mixing process improves the cement particles' ability to separate and disperse, which in turn greatly lowers the water requirement in flowable concrete.

Mechanism
Auracast 50 is a strong superplasticizer that allows for the production of consistent concrete properties at the required dosage .

Main Uses of Fosroc Auracast 50
Auracast 50 is primarily used in the following applications:
Precast Concrete Elements
Fosroc Auracast 50 is perfect for precast concrete elements like hollow core slabs, cement tiles, kerbstones, edgings, and other items for garden landscape design, building blocks, and bricks.
High Early Strength Concrete
It is ideal for concrete requiring high early strength without the need for steam curing.
High-Performance Concrete
Auracast 50 is also used in high-performance concrete applications, where reduction in cycle time and early strength are required.

Advantages of Fosroc Auracast 50
Using Fosroc Auracast 50 brings several advantages to concrete production, including :
Low Viscosity : 
It is a low viscosity admixture suitable for precast elements, providing better flowability and workability.
High Early Strength : 
Auracast 50 enables high early strength without increasing cement content or reducing workability, making it ideal for precast concrete production.
Improved Surface Finish : 
Using Auracast 50 in concrete mixtures results in a smoother and more visually appealing surface finish.
Minimized Early Handling Damage : 
Due to its high early strength, Auracast 50 minimizes the risk of damage from early handling of precast elements.
Enhanced Durability : 
Concrete treated with Auracast 50 exhibits better resistance to carbonation, increasing the overall durability of the structure.
Reduced Shrinkage and Creep : 
Auracast 50 helps reduce shrinkage and creep in concrete, leading to long-lasting and stable structures .
Decreased Efflorescence : 
The use of Auracast 50 in concrete reduces efflorescence, preventing unsightly white deposits on the surface of concrete structures.

Standard Compliance
When it comes to superplasticizers, Fosroc Auracast 50 meets both IS:9103:1999 and ASTM C 494 Type F.

Technical Support
Fosroc's on-site technical advising services include help with things like mix design, admixture selection, trial evaluations, and dosing tools.

Properties
Some essential properties of Auracast 50 include:

• Appearance: Light yellow to brownish colored liquid
• pH: Minimum 6.0
• Chloride content: As per BS EN: 480-10-1997
• Relative density: 1.04 + 0.02

Dosage
The optimal dosage of Auracast 50 to meet specific requirements should always be determined by trials using the materials and conditions experienced in use. The normal dosage range is between 0.2 to 2.0 liters/100 kg of cementitious material.

Dosage Beyond Limits
Dosage beyond limits can be used to meet particular mix requirements in consultation with Fosroc technical department.

Effects of Overdosing
Overdosing may cause a delay in the setting time and segregation of the concrete mixture.


Estimating, Packaging, and Storage
Auracast 50 is available in 200 kg and 20 kg drums and bulk tankers . It has a minimum shelf life of 12 months, provided the temperature is kept within the range of 2°C to 50°C .

Precautions

Health and Safety Instructions
Current standards do not classify Auracast 50 as a hazardous material. It's important to keep it away from your skin and eyes, so don't ingest it. Gloves and eye protection of the appropriate type should be worn.

Fire
Water and fire are not issues with Auracast 50.

Cleaning and Disposal
In the event of an Auracast 50 spill, the substance should be contained by absorbing it into sand, dirt, or vermiculite.. Remnants should be hosed down with a large quantity of water. Dispose of excess or waste material according to local legislation under the guidance of the local waste regulatory authority.

Conclusion
Fosroc Auracast 50 is a high-performance precast superplasticizer that offers a range of benefits for concrete production, including improved workability, high early strength, enhanced durability, and reduced shrinkage and creep. Manufactured by Fosroc Chemicals India Private Limited and marketed by Space Arc Engineering, this product is an essential solution for precast concrete elements and high-performance concrete applications.
