Water Reducer

Water Reducer 420 is a plasticizer designed to be especially effective with mixes that have a high content of finer sands and particles. It can be used to achieve a homogeneous flow in mixes with high fines, a softer flow in mixes like GFRC, and can soften a mix slightly without imparting too much sag or slump. Water Reducer 420 is often used to temper mixes that have been plasticized with Water Reducer 310 or Water Reducer 205. This combination of water reducers allows the fabricator a wide range of possibilities in responding to environmental conditions.

Dosage Rate: 0.1- 2% of Cement Weight

The ultimate indicator of an overdosage of plasticizer is segregation of the mix. Make test batches prior to production to ensure optimum dosage.

Adding Water Reducers will increase workability of concrete mixes that have a low water to cement ratio. Maintaining a low water to cement ratio is critical for reaching optimal strength in the cured matrix.

Water Reducer 555 is a high efficiency polycarboxylate-based superplasticizer in liquid form. It is ideally suited for use when making Self-Consolidating Concrete (SCC). Water Reducer 555 has been formulated to provide maximum workability without segregation to concrete.

Recommended Dosage Rate: 8 to 20 fluid oz per 100 lbs. of cement (540 to 1400 mL per 100 kg). This is equivalent to a dosage range of 0.5% to 1.4% of cement weight. Dosage rates will vary depending on the materials used, mix design, ambient conditions and the requirements of a specific project. Make test batches of 10-20 lbs (5-10 kg) of concrete until you are familiar with Water Reducer 555's effect on your mix.

Mixing: Water Reducer 555 can be added with the initial batch water, but delayed addition will generally result in optimal water reduction. Mixing Water Reducer 555 with the batch water first yields improved mixing efficiency, while delayed addition allows for fine-tuning of the mix consistency. When adding incrementally, mix the concrete for 2 to 5 minutes before adding more. Adding too much superplasticizer is easy to do, and it can result in segregation.
