감수제

감수제는 물 사용량을 줄이고 콘크리트의 내구성과 기능성을 향상시키는 데 도움을 주는 혼화제입니다.. The first 감수제 was used in the United Kingdom in the 1930s. Other countries like Japan and the United States have developed the technology of using this admixture.

일반적으로, water reducing admixtures fall into three categories: 낮은, 중간, 그리고 높다. Low range reduces the amount of mixing water by more than twelve percent; medium range reduces it by more than fifty percent; and high range increases it by more than ten percent.

Lignosulfonates were the first class of 감수제에스. They are a mixture of a polymer electrolyte and a water-soluble multifunctional substance. These two compounds have the property of dispersing dirt and calcium phosphate, and they can also disperse biological slime and zinc ions. In addition to being used as a 감수제, these substances are also commonly used as waterproofing agents.

Water reducing agents are usually made of an anionic surfactant. It has two parts: a hydrophilic group and a hydrophobic group. These are typically mixed with other chemicals.

Sodium lignosulfonate is a common 감수제. Lignosulfonates can be used as a sulphonating agent and alkali neutralizing agent. They can also be used as a catalyst.

Melamine is a high-efficiency 감수제. Melamine is prepared from a sulfonating agent and an aldehydic acid molecule. This type of 감수제 has very high efficiency and is suitable for engineering with a good flowability and excellent durability.
