Chryso®WRDA

Water-Reducing Admixture: Better concrete, without downsides.

Chryso®WRDA Water Reducers

Increased Workability, Durability & Finishability

Producers can enjoy more workability without adding more water? The products comprising of Chryso®WRDA Water Reducers are designed to increase the workability, finishability and durability of concrete. Better still, these products are made with pure chemicals and not by-products, and have no impact on air entrainment.

The Chryso®WRDA family of water reducers provide superior water reduction, compressive strength, and set time control. Designed for versatility, these products work synergistically with other polycarbonate based mid- and high-range water reducers.

Additional formulations allow for more specialized applications. Chryso®WRDA admixtures are fully compatible with other polycarboxylate based admixtures.

Products

WRDA® PA

WRDA® PA is a non-chloride, highly purified and polymer based water-reducing set-accelerating admixture formulated to produce concrete with enhanced water reduction.

WRDA® PA 100

WRDA® PA 100 is a non-chloride, PC-based water-reducing set-accelerating admixture that combines the benefit of water reduction, shorter finishing time and superior strength development.

WRDA® PN

WRDA® PN is an aqueous solution of highly purified polycarboxylate and carbohydrates. WRDA® PN is a dispersing agent which provides uniform, predictable performance. As a dispersing agent, WRDA® PN lessens the natural inter-particle attraction between cement grains in water. It does this by absorbing itself onto the cement particle reducing their tendency to clump together, resulting in the mix being more workable with less water. WRDA® PN is also formulated with set and strength catalysts which promote more complete hydration of cement and Pozzolan materials. WRDA® PN contains finishability agents that provide enhanced “slickness” to the surface of the concrete. This allows for easier trowelling, resulting in a greatly improved finish to the concrete as compared to what can be achieved using conventional water reducers. WRDA® PN will also assist in producing concrete that will pump better due to the finishability agents that are used. WRDA® PN complies with AS 1478.1-2000, type WR.

WRDA® PN 20

WRDA® PN 20 is an aqueous solution of polycarboxylate polymers and hydrocarbons. It is a dispersing agent which provides uniform, predictable performance.

WRDA® PN 40

WRDA® PN 40 is an aqueous solution of highly purified polycarboxylate and carbohydrates that contains finishability agents that provide enhanced “slickness” to the surface of the concrete.

WRDA® PWN

WRDA® PWN is an aqueous solution of polycarboxylate polymers and hydrocarbons. It is a dispersing agent which provides uniform and predictable performance.
