HIGH RANGE WATER REDUCING ADMIXTURE FOR CONCRETE High range water reducing admixture (ASTM C494 types F and G) decreases the water/cement ratio and provides high-performance, particularly at early ages. Matching the chemical admixture to the cementitious materials, both in type and dosage rate is important. Slump loss characteristics of the concrete will determine whether the high range water reducer should be introduced at the plant, at the site, or both locations. However, with the advent of newer generation products, sufficient slump retention can be achieved through plant addition in most cases. High range water reducers can be used in one or a combination of the following ways while minimally affecting setting time: 1. Reduce the water-cement ratio while maintaining slump. 2. Increase slump while maintaining a constant water-cement ratio. 3. Reduce the cementitious materials content and water content while maintaining constant slump and strength. High range water reducers may serve the purpose of increasing strength through a reduction in the water-cement ratio while maintaining equal slump, increasing slump while maintaining equal water-cement ratio or a combination thereof. The method of addition should distribute the admixture uniformly throughout the concrete. Adequate mixing is critical to uniform performance. Problems resulting from non-uniform admixture distribution or batch-to-batch dosage variations include inconsistent slump, rate of hardening, and strength development. Most of the commercial formulations of high-range water-reducers belong to one of the following categories: · Sulfonated melamine-formaldehyde condensates. · Sulfonated naphthalene-formaldehyde condensate · Modified lignosulfonates. · Polycarboxylate derivatives. Sika® ViscoCrete® 2100 High Range Water Reducing Admixture Description Sika ViscoCrete 2100 is a high range water reducing and superplasticizing admixture utilizing Sika‟s „ViscoCrete‟ polycarboxylate polymer technology. Sika ViscoCrete 2100 meets the requirements for ASTM C-494 Types A and F. Applications Sika ViscoCrete 2100 may be used in both ready mix and precast applications, as a plant added high range water reducer to provide excellent plasticity while maintaining slump for up to 90 minutes. Controlled set times make Sika ViscoCrete 2100 ideal for horizontal and vertical applications. Sika ViscoCrete 2100 is ideal for production of Self Consolidating Concrete (SCC). Advantages Water Reduction: Sika ViscoCrete 2100 can be dosed in small amounts to obtain water reduction from 10-15%, and will achieve water reduction up to 45% at high dosage rates. Sika ViscoCrete 2100 is suitable for all levels of water reduction. High Plasticity: The superplasticizing action of Sika ViscoCrete 2100 provides high-slump, flowing concrete that maintains excellent workability and may be placed with minimal vibration even at very low water cement ratio‟s as low as 0.25. Sika ViscoCrete 2100 plasticized concrete is highly fluid while maintaining complete cohesion within the concrete matrix to eliminate excessive bleeding or segregation. Extended Slump Life and Set Control: Sika ViscoCrete 2100 has been formulated to provide controlled and predictable extended slump life for periods of 60 to 90 minutes with normal set times. The combined high range water reduction and superplasticizing action of Sika ViscoCrete 2100 provide the following benefits in hardened concrete: n Higher ultimate strengths allow for greater engineering design flexibility and structural economies. n Reduced water cement ratios produce more durable, dense concrete with reduced permeability. n Highly effective plasticizer reduces surface defects in concrete elements and improves aesthetic appearance. It has been formulated to provide maximum water reduction and extended slump retention at low dosages. How to Use Dosage Dosage rates will vary according to materials used, ambient conditions and the requirements of a specific project. Sika recommends dosage at 1-6 fl. oz. per 100 lbs. (65-390 ml/100 kg) of cementitious materials for conventional concrete applications. If high slump or Self Consolidating Concrete (SCC) is required, typically dosage from 5-12 fl.oz./100 lbs. (325-780 ml/100 kg.) of cementitious materials may be used. Dosage rates outside the recommended range may be used where specialized materials such as microsilica are specified, extreme ambient conditions are encountered or unusual project conditions require special consideration. In this case, Please contact your local regional Sika office or Sika Technical Service Department 1-800- 933-7452 for more information and assistance.
