MTOCRETE N-540
Super-lubricating and super-reducing concrete water additive
Explanation:
MTOCRETE N-540 is a superplasticizer and water reducer additive with delayed setting properties, designed for producing high-performance flowing concrete with minimal water-to-cement ratio while maintaining slump for a short period. It has the capability to reduce water in concrete mixtures by up to 25% while keeping the slump constant, leading to increased compressive strength and durability of the concrete.
It is effective in dispersing cement particles, fly ash, and microsilica, preventing their tendency to clump together. This results in a homogeneous distribution of cement paste in the mix, allowing trapped water between particles to be released. This action enhances the effective surface area of cement during the hydration process.
Application and uses:
The MTOCRETE N-540 is designed for producing flowing concrete without increasing water for:
Concrete with high steel fiber content
Special architectural concrete
Precast concrete
High-rise buildings
The MTOCRETE N-540 is a superplasticizer that can be used to make high-performance concrete with reduced water-to-cement ratio for:
Pre-tensioned concrete
Precast concrete
High-rise buildings
Advantages of using MTOCRETE N-540
Improving the rheological and mechanical properties of concrete such as
Efficiency, compressive and bending strength and modulus of elasticity
The physical and chemical properties of sodium sulfonate-based compounds are as follows:
Chemical composition: Sodium sulfonate-based compounds
Improved chemical composition
Brown color
Ionic nature: Anionic
Physical state: Liquid
pH range: 1-8
Chloride (PPM) maximum limit: 500
Specific gravity (kilogram per liter) at 20 degrees Celsius: 0.02-1.2
Consumption:
The recommended dosage of MTOCRETE N-540 is between 0.5 to 2.5% of the weight of the cementitious materials, depending on the mixing design and required properties. It is suggested to conduct tests at the job site with the available materials and conditions to determine the optimal dosage of MTOCRETE N-540 and its impact on the properties of fresh and hardened concrete, such as workability, durability, and initial and final test results.
Usage:
It can be mixed ready for use with water in any ratio.
It can be added simultaneously with the mixing water to the mixer.
It should not be directly added to cement and dry components.
At the end of the mixing process, it can be added to the batching mixer or inside the transit mixer. In this case, for each cubic meter, one minute of mixing at high speed should be performed.
Compatibility with cement compounds:
The compatibility of MTOCRETE N-540 with cementitious materials is suitable for use with various types of cement and alternative cementitious materials, including fly ash, microsilica, and ground granulated blast furnace slag.
The compatibility of MTOCRETE N-540 with other additives is as follows:
- It should not be pre-mixed or used with other additives unless authorized by the manufacturer.
- It is recommended to consult with the technical unit of the Green Concrete Aroma Company (Iran Concrete Technical and Specialized Clinic) in such circumstances.
Packaging:
MTOCRETE N-540 is supplied in 20-gallon containers and 250-kilogram barrels.
Storage recommendation:
It is recommended to store MTOCRETE N-540 in a temperature range of 5 to 40 degrees Celsius, away from direct sunlight. If the material freezes, raise the temperature until it melts and then mix it with a mixer.
Shelf life:
If preserved and stored in the recommended condition and in the package
The initial packaging can be stored for up to 12 months.
Safety:
MTOCRETE N-540 is a low-risk material. In condition
Normal does not harm the skin. But as a chemical compound
And observing precautions to avoid contact with the skin and with
Eye protection gloves and glasses should be used or after contact
Wash directly with skin or eyes with water.
