Liquid super-plasticizing admixture created on the basis of polycarboxylic polymer modification, especially intended for obtaining self-compacting concrete (SCC) and high-quality concrete (HPC). The product enables the preparation of concrete suitable for very advanced processing, characterized by high adhesion and no risk of delamination or water outflow, applied and compacted under the influence of its own weight, requiring only minimal tamping.

Features

• improves the distribution of concrete on densely reinforced surfaces and its bonding on surfaces that are difficult to access for processing
• allows for maximum water reduction
• applicability longer than other superplasticizers, but not slowing down the setting
• ensures high adhesion to fresh concrete without causing its delamination and water outflow
• reduces the proportion of water and cement, which enables the creation of very durable and dense concrete with very low permeability, increasing its resistance to carbonization, penetration by chloride ions and aggressive weather conditions
• Eliminates air bubbles, reduces porosity, improves surface finish and appearance
• the minimum proportion of water and cement reduces the risk of shrinkage during drying and "creep of the material"
• does not contain chloride or any other corrosive agents
• better efficiency, faster application, less labor-intensive when spreading concrete

Application

• concrete with high fluidity and workability with the smallest proportion of water and cement
• concrete with high initial and final strength is obtained
• for precast and prestressed concrete elements
• for application with thickened reinforcement
• the highest quality concrete is produced for use in all types of land and water works
