Durable concrete is defined by the quality and density of its binder matrix, which directly influences long term performance, resistance and sustainability. Durable concrete is defined not only by high compressive strength but by long term resistance to external influences. Achieving this requires expert concrete technology and the correct use of high-performance admixtures that improve impermeability, reduce porosity and enhance the density of the cement matrix. Protecting fresh concrete from premature drying, temperature extremes, rain, physical shock and chemical attack is essential to creating a consistent and cohesive hardened concrete structure. With advanced admixture technologies such as superplasticisers, air entraining agents, shrinkage reducing solutions and silica fume, it is possible to minimise defects, extend service life and support the sustainability of the concrete.
Advantages of Using Sika Concrete Admixtures for Durable Concrete
