integral waterproofing การใช้

Another important type of admixture for VDT concrete is integral waterproofing formulas.
There are two main types of integral waterproofing systems : the hydrophilic and the hydrophobic systems.
Tests have shown that some of these integral waterproofing admixtures have improved strength by as much as 20 % while reducing the absorption by 40 %.
On recent commercial testing laboratory results, the freeze-thaw for VDT concrete using integral waterproofing admixtures was 0.23 % weight loss after 300 cycles.
From the late 1990s to the 2010s, the construction industry has had technological advances in waterproofing materials, including " integral waterproofing systems " and more advanced membrane materials.
