Sikament 686 High Range, Water Reducer and Superplasticizer, Normal Slump, 55 Gallon Drum
Sikament®-686 is a high-range water-reducing admixture utilizing Sika’s ViscoCrete® Technology. Its unique formulation is based on polycarboxylate technology. Sikament®-686 meets the requirements for ASTM C-494 Types A and F admixture.
Uses:
Sikament®-686 is recommended for use in the production of all high-strength concrete products, whenever high plasticity and increased early and ultimate strengths are desired. The superplasticizing action of Sikament®-686 provides excellent workability at low water cementitious ratios.
Advantages:
High Range Water Reducing Applications: When used as high range water reducing admixture, water reduction of up to 30 % can be obtained. The superplasticizing action allows for the production of high slump-flowing concrete with excellent workability that can be placed with minimum vibration even at a low water/cementitious ratio. The dispersing action of Sikament®-686 maximizes cement hydration efficiency and improves concrete’s early and long-term compressive strengths.
Mid Range Water Reducing Applications: At a lower dosage, Sikament®-686 can be used as a cost-effective mid-range water-reducing admixture or simply as a water-reducing admixture for the production of conventional slump concrete. When used as mid-range water reducing admixture, water reduction up to 15 % can be obtained. This application is ideal for use with lean, harsh concrete mixes or concrete containing fly ash. Sikament®-686 will improve workability and finishability. The combined water reducing and superplasticizing action provide the following benefits:
Sikament®-686 does not contain calcium chloride or any other intentionally added chlorides and will not initiate or contribute to corrosion on steel reinforcement present in the concrete.
