Riteks VMA-42

Riteks VMA 42 has little effect on the compressive strength of concrete. If a lower water-cementitious ratio or higher compressive strength is necessary, the use of additional high-range water reducer is recommended. Bleed water is significantly reduced and may be eliminated in concrete mixes. A slight decrease in slump should be expected after the addition of VMA 42 due to the increase in viscosity of the mix. An additional dose of high-range water reducer may be necessary to meet the specified slump for placement. Slump retention will be similar to normal concrete mixes. When used within the recommended dosage range, VMA 42 has very little effect on set time. The air-entraining admixture dosage requirement will remain the same as typical concrete mixes. It is recommended for use at a dosage rate of 1 to 15 fluid ounces per 100 pounds (65 to 980 mL per 100 kg) of cementitious materials for most applications. Because local job conditions, materials, and applications vary, this product may require dosages outside the recommended dosage range.
