Ura murrizteko agentea

Ura murrizteko agente nahasketa bat da, uraren kontsumoa murrizten eta hormigoiaren iraunkortasuna eta funtzionaltasuna hobetzen lagun dezakeena.. The first ura murrizteko agentea 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.

Normalean, water reducing admixtures fall into three categories: baxua, medium, 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 ura murrizteko agenteas. 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 ura murrizteko agentea, 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 ura murrizteko agentea. 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 ura murrizteko agentea. Melamine is prepared from a sulfonating agent and an aldehydic acid molecule. This type of ura murrizteko agentea has very high efficiency and is suitable for engineering with a good flowability and excellent durability.
