New grouting mortars Emcekrete 70 F and Emcekrete 100 F
Dec 04, 2017
Nowadays, grouting mortars are regularly used on building sites, whether for grouting machine baseplates on a concrete foundation or rigid joints between precast concrete components and/or in-situ concrete. Now, MC-Bauchemie has launched two new high-performance grouting mortars onto the market in the form of Emcekrete 70 F and Emcekrete 100 F, both offering outstanding flowability combined with high strength values, low shrinkage and exceptional resistance.
Emcekrete 70 F and Emcekrete 100 F are based on an innovative binder matrix developed by MC-Bauchemie that promotes high flexural and compressive strength together with exceptional resistance and durability. The ideally coordinated, micro-fine particle grading of the two grouting mortars results in optimised packing densities down to the micron range. Both these high-performance grouting mortars are chloride-free. They just have to be mixed with water to be ready to use. They are pumpable and, once solidified, water-impermeable, resistant to frost and de-icing salt, fully shrinkage-compensated and non-combustible in accordance with EN 13501 (building material class A1). Grouting depths of 10 to 75 mm can be achieved with both products.
Emcekrete 70 F for high early and final strength values combined with an attractive surface finish
Emcekrete 70 F is a highly flowable, low-shrinkage grouting mortar which achieves both high early and high final strength values. After just two to four hours, it develops compressive strength levels in excess of 10 N/mm²*. After 28 days, this figure will have increased to more than 70 Nmm2*. It is ideal for the grouting of precision machinery, power generating plant and machine foundations for units such as turbines, generators, compressors and motors that are exposed to high dynamic loads, plus anchors, supports, steel and concrete columns and bridge bearings. It can also be used for the grouting of steel constructions, fixing bolts, steel fasteners and reinforcing bars in concrete (in compliance with the strict requirements of EN 1504: Part 6) and also of rigid joints between precast components and/or in-situ concrete, not to mention wind power generators.
This grouting mortar likewise offers extensive scope for design in a wide range of applications: exhibiting easy workability, a fine and aesthetically attractive surface quality and ready suitability for pigmentation, Emcekrete 70 F is also suitable for the manufacture of small crafted concrete products such as washbasins, lamps, candelabras and even concrete jewellery.
Emcekrete 100 F for ultra-high final strength values
Emcekrete 100 F is ideal for applications requiring ultra-high final strength values. In the first 24 hours, Emcekrete 100 F already achieves standard levels of flexural and compressive strength of 7.5 and 42 N/mm2* respectively. Exceptionally high compressive strength values of 100 N/mm2* are achieved after seven days, rising to over 120 N/mm2* after 28 days. Emcekrete 100 F, like Emcekrete 70 F, can be used for grouting precision machinery, machine foundations, steel components and similar. In addition, this high-performance mortar is particularly suitable for the grouting of wind power generators. Emcekrete 100 F further fulfils the requirements of the German Committee for Structural Concrete (DAfStb) guideline for the “Production and use of cement-bound grouting concrete and grouting mortar” in Germany.
