SikaPlast®-500
SikaPlast®-500 is a mid range water reducing admixture utilizing Sika’s ViscoCrete® Technology. It’s unique formulation is based on latest polycarboxylate technology.
- Higher early and ultimate strengths
- Increased slump improves ease of placement and reduces labor costs
- Reduced water/cementitious ratio reduces permeability and increases durability
Usage
- SikaPlast®-500 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 SikaPlast®-500 provides excellent workability at reduced water cement ratios. SikaPlast®-500 is specifically suitable in following applications:
- Concrete slabs
- Concrete footings
- Concrete paving
- Harsh mix designs with low cement content
Advantages
Low Range Water Reducing Applications: SikaPlast®-500 can be used as an economical low dosage admixture for conventional slump concrete, where water reduction up to 5 % is required. SikaPlast®-500 shows similar setting properties as a reference concrete. By reducing water, SikaPlast®-500 improves durability and increases compressive strength. Mid Range Water Reducing Applications: Mid range application will be beneficial especially in ready mix applications. At a medium dosage, SikaPlast®-500 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 12 % can be obtained. This application is ideal for use with lean, harsh ready mix concrete mixes or concrete containing fly ash. SikaPlast®-500 will improve workability and finishability. High Range Water Reducing Applications: When used as a high range water reducing admixture, water reduction up to 20 % 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 SikaPlast®-500 maximizes cement hydration efficiency and improves concrete’s early and long term compressive strengths. The combined water reducing and superplasticizing action in all three cases provide the following benefits:- Higher early and ultimate strengths
- Increased slump improves ease of placement and reduces labor costs
- Reduced water/cementitious ratio reduces permeability and increases durability

Application
Mixing
For best plasticizing results, SikaPlast®-500 should be added directly to freshly mixed concrete in the concrete mixer at the end of the batching cycle. SikaPlast®-500 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: SikaPlast®-500 is highly effective as a single admixture or in combination with other admixtures. Contact your local Sika Sales Representative for further information.
Combination with pozzolanic materials: SikaPlast®-500 can be successfully used in mix designs utilizing pozzolanic materials such as fly ash and GGBFS
Recommended Dosage
For general concreting applications, recommended dosage rate is 195-780 mL/100 kg (3-12 fl.oz /100 lb) of cement. Dosage rates will vary depending on the material used, ambient conditions and the requirements of a specific project.
Where maximum water-reduction is required, dosage of up to 1170 mL per 100 kg (18 fl.oz/100 lb) of cementitious material may be used. In this case, delayed setting times will likely 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. In these cases, contact your Sika Canada Technical Sales Representative for further information.
