White flower prevention cement "Tsuge Cement"

basic information

The efflorescence phenomenon occurs immediately after construction and can also develop over the long term, significantly damaging the design in both cases. While there are additives available on the market that can somewhat suppress efflorescence, "Tsuge Cement" is the only cement that prevents this phenomenon. (Developed in collaboration with Kenji Watanabe, Professor at Chubu University and a first-class architect) The principles of "Tsuge Cement" are as follows: 1. Blocking the calcium migration pathway by mixing in crack reinforcement materials. 2. Reducing the total amount of calcium by decreasing the usage of ordinary Portland cement. 3. Incorporating calcium capture materials that are not affected by the setting or strength of the concrete. These actions form independent voids and reduce and disperse fine cracks, preventing water intrusion. The amount of calcium used is lower than that of conventional products, and in the unlikely event that calcium tries to leak out, the capture materials prevent the substances causing efflorescence from surfacing. Additionally, it is composed of inorganic materials and contains reinforcement materials, making it resistant to acids and exhibiting minimal shrinkage changes, similar to non-shrink cement. It can be used just like regular cement (1 bag/20kg). *For more details, please download the catalog PDF or feel free to contact us.*
