Synthesis And Properties Of Cement Waterproofing Agent

In the building structure project, the infiltration question has been a difficult disease of perplexing in the project circle all the time, it has been the important subject that the scientific research personnel have put forth effort to research on and solve over the years, but the results have little. The development of the waterproof material of our country starts relatively late, but its development is very fast .Up till now, the waterproof material of our country has been already developed into two great main classifications: Flexible material and rigidity material. It is a kind of waterproof technology called "giving temporary relief in the flexible material. Its shortcoming is that the term of validity service time is relatively short, easily loss and damage, difficult to repair, mostly poisonous, costliness, and this kind of waterproof being apt to come off because of its bigger shape transmogrification. The rigidity material utilizes the materials with the cement, sand, stone, mix and add a small amount of inorganic or organic admixture. It is a kind of waterproof technology called "getting a permanent cure". The waterproof material of new and high-efficient rigidity has become the development trend of the waterproof material in the future.The paper has studied on and developed a subject of high-efficient waterproof material complying with trend of waterproof material development, according to the current development state of waterproof material of our country .We got new-style and high-efficient organic waterproof material with self-healing effect. According to JC474-99 standard, this kind of waterproof material performances have met and exceeded the requests of Grade A in the waterproof and strength performances, and it is cheap and easy to construct. It is a kind of waterproof material of new-style rigidity which will be used well in the future.
