MTOAIR 220 concrete foaming additive Clinic Beton Iran

MTOAIR 220 concrete aerating additive is very stable in producing air bubbles, these bubbles are strong, small and close together. Concrete encapsulating additive to produce very stable, strong, small and close air bubbles based on ASTM C260-86, AASHTOM-154 standards.
A high performance concrete superplasticizer based on modified polycarboxylate

Applications of MTOAIR 220 concrete aerating additive:

1. Entering controlled air in a wide range in all types of concrete
2. Typical mixing scheme
3. Lack of mental
4. High carbon fly ash content
5. The content of large amounts of fine-grained materials
6. High cement or alkali content
7. Concreting in hot weather
8. Long mixing time

Properties and effects of MTOAIR 220 concrete foaming additive

MTOAIR 220 aerating concrete admixture is especially useful for concretes that require some air to enter and maintain due to re-curing problems. Introducing the optimal limit of air bubbles in concrete leads to the following qualitative improvements:

• Increased resistance to freeze and thaw cycles
• Reducing permeability and thus increasing waterproofing properties
• Reducing separation and shedding
• Mental improvement and functionality
• Ready solution makes it spread better

MTO AIR 220 concrete encapsulating additive is compatible with all concretes containing other additives such as extreme water reducer, quick setting, thickener and water barrier. It also increases the amount of air introduced by Portland cement with aerating properties. The use of MTO AIR 220 concrete bubbler additive along with other additives of Iran Concrete Clinic form a suitable combination for the production of ordinary and lightweight concrete with excellent quality.

Additive packaging of MTOAIR 220 concrete bubbler:

MTOAIR 220 is available in 25 kg gallons, 220 kg drums and large tanks.

Physical and chemical characteristics of MTOAIR 220 concrete foaming additive:

• Specific gravity: 0.986 to 1.036 grams per cubic centimeter
• Color: amber or pale brown
• Chloride content: less than 0.1%
• Flammability: non-flammable
• Freezing degree: -1°C
• Alkaline number: 7 to 8

MTOAIR 220 concrete foaming admixture considerations

1. According to ASTM C-182 standard, 3 minutes of rest and 2 minutes of final mixing
2. 13 minutes of gentle stirring and 2 minutes of mixing
3. Shake and mix for 2 minutes

Applications of MTO AIR 220 concrete foaming additive:

According to ACI, when 2 or more additives are used, they must be added separately to the mixture. (By means of a distributing device or by hand and they should not be mixed together before adding concrete.)

MTO AIR 220 concrete foaming additive performance

For optimal performance, it is better to add aerating material to wet soft sand. Add MTOAIR 220 to the mixture using a special bubbler dispenser and a hand measuring tool that has an accuracy of plus or minus 3%.

Amount of MTO AIR 220 concrete foaming additive consumption:

There is no standard for the amount of bubble maker to use. The required amount of foaming additive should be determined by conducting workshop tests. The effective factors are: temperature - cement - material grading - percentage - composition - aggregates - slump - methods of transferring and spreading concrete and consumption of fine particles such as fly ash and microsilica.
The consumption amount of MTOAIR 220 is dependent on the amount of air needed in the working conditions and in the experimental design, amounts of 60 to 200 ml per 100 kg of cement were used and then its adjustment was done based on the results obtained. In designs with water-reducing or setting-controlling additives, the value of MTOAIR 220 is lower than that required for normal concrete.

How to store MTOAIR 220 concrete foaming additive:

MTOAIR 220 concrete foaming additive must be stored and used at a temperature higher than +2 degrees Celsius. Although freezing does not harm this product, caution is necessary to prevent freezing. If it freezes, heat it and stir slowly until it is completely recycled. Use compressed air to mix. If the above conditions are met, the useful life of this product is 12 months.
