Mid Range Water Reducing Admixture
SikaPlast®-500 is a mid range water reducing admixture utilizing Sika’s ViscoCrete® Technology. It’s unique formulation is based on latest polycarboxylate technology. SikaPlast®-500 is designed to meet the requirements for ASTM C-494 Types A and F.
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.
SikaPlast®-500 does not contain calcium chloride or any other intentionally added chlorides and will not contribute to corrosion on steel reinforcement present in the concrete.
