New waterproofing admixture for concrete goods

Oct 28, 2020

With Murasan Hydrotech 883, MC-Bauchemie has launched a waterproofing solution for the production of both semi-dry and wet-cast concrete goods. With this new hydrophobic admixture, concrete goods manufacturers can improve the resistance of their products to water penetration, significantly reduce moisture-related damage, and minimize efflorescence. 

During concrete hardening, any water that is not used for cement hydration evaporates.  This process leaves the cement matrix filled with a network of interconnected pores and capillaries, through which water can be absorbed by capillary forces – not unlike a sponge. When it comes to concrete, penetrating moisture can cause several problems. When water freezes, for example, its volume increases by about 9%. The resulting internal pressure can lead to mechanical damage such as spalling and development of fine cracks, which further accelerates concrete degradation. Besides, diffusing water can carry a variety of aggressive chemicals and significantly contributes to secondary efflorescence.

 

With Murasan Hydrotech 883, the new high-performance waterproofing admixture from MC-Bauchemie, concrete goods manufacturers can avoid such risks. As a silane-based product, it is tailored to the requirements of the concrete goods industry, specifically to the machine production of high-quality concrete goods such as paving stones, kerbstones, pathway slabs, channel blocks, and others.

 

Murasan Hydrotech 883 reduces the risk of water damage and ensures greater resistance to frost and de-icing salts. Introduced into the concrete mix with or after the addition of the mixing water, the hydrophobic agent provides for a better visual appearance both by minimizing efflorescence and by improving the colour uniformity, brightness, and surface texture of the concrete goods.
