Product Name: Sulphonated Aminophenol Based Superplasticizer (AS)
Type: AS
Package: 30kg/bag

Sulphonated Aminophenol Based Superplasticizer

■ Description

Amino-Arylsulphonate Phenol Formaldehyde Condensate(AS)is a high range water reducer, commonly referred to as superplasticizer. It is composed with modified amino sulphonate and organic compounds. It contains no chloride .

AS is non air-entraining, low addition rate, low slump loss, thus decrease the concrete viscosity. At normal condition, it can be prepared for flowable concrete of C60-C80 without using strength enhancing agent.

■ Standards Compliance
AS complies with ASTM C494, Type F standard for high range water reducer.

■ Uses
■ To obtain a high quality concrete mix with accelerated strength development and extended workability without delayed setting characteristics.
■ To provide a concrete mix with exceptional placing characteristics and accelerated cement hydration for early strength development and high quality concrete.
■ To provide improved durability by increasing ultimate strengths and reducing concrete permeability.

■ Typical Applications & Advantages
1.AS is compatible with Portland Cement, Portland Slag Cement, Fly-ash Cement, Portland   Pozzolanic Cement, etc.

2. Applicable in precast, ready-mixed concrete, flowable and self-compacting concrete and steam-curing concrete for both industrial and civil construction project.

3.  It can be applied on bridge deck projects or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy rendering and consolidation.

4.  It is also available as base material for compound admixtures, especially when mixed with Naphthalene-based superplasticizer, it can achieve better water reducing rate and high strength performance.

5. High water reducing rate: The water reducing rate is over 30%.

6. Low slump loss: It can satisfy the requirement of long time transportation. It is ideal for ready-mix and pumping concrete.

7. Early strength: It may reach to 70% of the designed strength grade in 3 days.

8. High durability: High volume stability, impermeability, anti-freezing and thawing ability makes concrete more durable.

9. Low alkali content: It can prevent alkali-aggregate reaction. When it is used in winter, there is no crystallization.

10. AS can make high-slump flowing concrete. It allows concrete to be produced at low water/cement ratios with low or normal slump loss.

■ Technical Support and Services

MUHU offers one-stop type services and turn-key project.

MUHU is well known in admixture manufacturing researching and developing. We have excellent professional technical team, providing our customers with on-site instruction on concrete admixture compounding techniques. Meanwhile, we also provide long-term training on admixture compounding techniques. In order to ensure that customers have no worries, we supply our customers who have purchased our equipment with various technical supports, including training on admixture compounding techniques, know-how transfer, and technical cooperation, etc. 

■ Instructions for Use
AS must preferably be added in the mixing water and in case of readymix concrete where the product can be added on fresh concrete and in a mixing truck, it is necessary to mix at a high speed for about 6 – 8 minutes.

■ Dosage
The optimum dosage of AS to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. When AS is applied in the form of powder, normal dosage ranges from 0.3% to 1.0% of the weight of cementitious material, while the suggested rate is 0.45% taking technical and economic factors into consideration.
Dosages outside the normal range quoted above can be used to meet particular mix requirements.
Contact MUHU for advice in these cases.

■ Setting
AS affords excellent control over initial and final setting times. Setting times of concrete mixes are related to cement type, mix design and ambient temperature.

■ Compatibility
AS should not be used in conjunction with any other admixture unless prior approval is obtained from MUHU.

■ Packaging & Storage
For powder: Woven fabric bag with plastic liner. Net weight: 30kg.
AS has a minimum shelf life of 12 months provided it is stored under cover, out of direct sunlight.

■ Health & Safety Precautions
AS does not fall into the hazard classifications of current regulations. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable protective gloves and goggles should be worn. Splashes on the skin should be removed with water. In case of contact with eyes rinse immediately with plenty of water and seek medical advice. If swallowed seek medical attention immediately –do not induce vomiting.
