Mid Range Water Reducers - Sikament® AFM
Mid Range Water Reducing Admixture
Sikament® AFM is a mid range water reducing admixture utilizing Sika’s ViscoCrete® Technology. It’s unique formulation is based on latest polycarboxylate technology. Sikament® AFM is designed to meet the requirements for ASTM C-494 Types A and F.
Mid Range Water Reducing Applications: Mid range application will be beneficial especially in ready mix applications. At a lower dosage, Sikament® AFM can be used as a cost effective mid range water reducing admixture or simply as a water reducing admixture for production of conventional slump concrete. When used as a mid range water reducing admixture, water reduction up to 15 % can be obtained. This application is ideal for use with lean, harsh ready mix concrete mixes or concrete containing flyash. Sikament® AFM will improve workability and finishability.
High Range Water Reducing Applications: When used as a high range water reducing admixture, water reduction up to 25 % can be obtained. The superplasticizing action allows for the production of high slump flowing concrete with excellent workability that can be placed with minimum vibration even at a low water/cement ratio. The dispersing action of Sikament® AFM maximizes cement hydration efficiency and improves concrete’s early and long term compressive strengths. The combined water reducing and superplasticizing action provide the following benefits:
- Higher early and ultimate strengths for cost effective high strength concrete and earlier structural use of concrete.
- Increased slump improves workability and reduces labor costs.
- Full flow action aids in pumping and reduces need for vibration.
- Greater concrete density reduces permeability and increases durability.
Sikament® AFM does not contain calcium chloride or any other intentionally added chlorides and will not contribute to corrosion on steel reinforcement present in the concrete.
Usage
Sikament® AFM is recommended for use in the production of conventional ready mixed concrete, whenever high plasticity and increased early and ultimate strengths are desired. The superplasticizing action of Sikament® AFM provides excellent workability at reduced water cement ratios. Mid Range applications:
- Concrete slabs
- Concrete footings
- Concrete paving

Application
Application Information
MixingMixing for best plasticizing results, Sikament® AFM should be added directly to freshly mixed concrete in the concrete mixer at the end of the batching cycle. Sikament® AFM may also be dispensed as an integral material during the regular admixture batching cycle, or into freshly mixed concrete in a Ready-Mix truck at the concrete plant or job site. To optimize the superplasticizing effect, Sika recommends that the combined materials be mixed for 80-100 revolutions, either in the concrete mixer or in the Ready-Mix truck.
Combination with Other Admixtures: Sikament® AFM is highly effective as a single admixture or in combination with other admixtures. If used in combination with certain Sikament® high range water reducers, it may affect the plastic properties of fresh concrete.
Combination with Pozzolanic Materials: Sikament® AFM is particularly well suited for use with pozzolanic materials such as fly ash and GGBFS because of its water reduction capability.
Consumption
Recommended DosageDosage rates will vary depending on the material used, ambient conditions and the requirements of a specific project. For general concreting applications, Sika recommends a dosage rate between 3-12 fl. oz. / 100 lbs. (195-780 ml / 100 kg) of cementitious materials. If maximum water reduction is required, dosage up to 18 fl.oz. / 100 lbs. (1170 ml / 100 kg) of cementitious materials may be used. In this case, delayed setting times may occur.
Dosage rates outside the recommended range may be used where specialized materials such as microsilica are specified, extreme ambient conditions are encountered or unusual project conditions require special consideration.
