Murasan Hydrotech 883
MC-Bauchemie 推出用於半乾與濕澆混凝土產品的 Murasan Hydrotech 883 防水解決方案，借助此新型疏水性添加劑，可提高混凝土製品對水滲透的防護力，明顯減少潮濕造成的相關損壞，並大幅降低白華產生。
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.
