Sika® Stabilizer-440 RCR is an innovative admixture designed to convert returned concrete in its fresh state into solid granules, which can be repurposed as other building materials. This breakthrough solution is conveniently packaged in water-soluble bags, allowing for easy and direct discharge into concrete trucks. It is compatible with all cement types and mix designs, making it a versatile option for ready-mixed concrete returned from construction sites across various projects.

The application process is simple and efficient: after adding the admixture to the returned concrete, a mixing time of just 3–8 minutes is required. Once mixed, the treated concrete can be unloaded and reprocessed using standard machinery available at any concrete plant. This streamlined process enables quick conversion of what would otherwise be waste concrete into reusable materials, significantly reducing downtime and enhancing productivity.

A key advantage of Sika® Stabilizer-440 RCR is its ability to drastically cut costs and save time for concrete users and manufacturers. By treating returned concrete before it hardens, the need for expensive and time-consuming disposal processes is eliminated. This not only results in financial savings but also optimizes resource usage, promoting greater efficiency and sustainability within construction projects. Sika® Stabilizer-440 RCR is a valuable tool for reducing waste and enhancing the eco-friendliness of construction operations.
