پانی کو کم کرنے والا ایجنٹ

پانی کو کم کرنے والا ایجنٹ ایک ایسا مرکب ہے جو پانی کے استعمال کو کم کرنے اور کنکریٹ کی استحکام اور فعالیت کو بہتر بنانے میں مدد کر سکتا ہے۔. The first پانی کو کم کرنے والا ایجنٹ 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.

عام طور پر, water reducing admixtures fall into three categories: low, درمیانہ, and high. 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 پانی کو کم کرنے والا ایجنٹs. 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 پانی کو کم کرنے والا ایجنٹ, 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 پانی کو کم کرنے والا ایجنٹ. 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 پانی کو کم کرنے والا ایجنٹ. Melamine is prepared from a sulfonating agent and an aldehydic acid molecule. This type of پانی کو کم کرنے والا ایجنٹ has very high efficiency and is suitable for engineering with a good flowability and excellent durability.
