Master Builders Solutions® introduces an innovative admixture to extend service life of concrete

MasterLife SRA 900 effectively reduces shrinkage and crack formation to produce high-quality, durable concrete

• Extends the service life of concrete by reducing crack widths
• Reduces shrinkage by up to 60 percent
• Ensures high-quality concrete

LUDWIGSHAFEN, Germany, 09-Oct-2018 — /EuropaWire/ — With MasterLife SRA 900, Master Builders Solutions^® is introducing an innovative admixture to extend the service life of concrete. The premium solution in the new MasterLife SRA series effectively reduces shrinkage and crack formation to produce high-quality, durable concrete.

Shrinkage normally describes a reduction in the volume of concrete independent of loading as a result of changes in its moisture content. Two well-known types of shrinkage are drying as a result of the progressive hydration of the cement (autogenous shrinkage) and drying shrinkage as a result of the release of moisture to the surroundings. All types of shrinkage may lead to cracking which can pose a risk to the durability of the concrete.

MasterLife SRA 900: solution for effective shrinkage reduction
For the effective reduction of shrinkage, Master Builders Solutions has developed the innovative admixtures in the MasterLife SRA series: “They reduce both the autogenous and the drying shrinkage of ready-mixed and pre-cast concrete. The other mechanical properties of the concrete are not impaired as the chemical mechanism only reduces internal capillary forces”, explained Raphael Breiner, Product Manager for Concrete Admixture Systems at BASF.

The benefit to the customer: even with a dosage of only one percent referred to the cement weight, the highly effective liquid concrete admixture MasterLife SRA 900 reduces the shrinkage of concrete by up to 60 percent. This makes for reduced crack formation and a longer service life. The admixture is compatible with a variety of different types of cement, has no impact on superplasticizer dosage and reaches class A+ in VOC emissions for all relevant samples.

MasterLife SRA is especially recommended for concrete mixtures with a high cement content, for applications under unfavourable weather conditions including heat, wind and sunlight, and for elements with large cross sections. The admixtures are suitable both for ready-mixed concrete and for the production of pre-cast and pre-stressed elements. The end product is high-quality, durable concrete, for example for facade cladding, structures subject to hydraulic stress, road surfaces and all applications where minimum crack formation and wide joint spacing are required.
