Polycarboxylate acid superplasticizer is currently the best-selling series of superplasticizers. It is a concrete additive in the construction industry. It plays a very important role in construction work. Today, we will mainly introduce our Polycarboxylate acid superplasticizer.
Polycarboxylic acid water reducer is a series of water reducer, it is a high performance water reducer. Usually used in cement concrete. It becomes a dispersant of cement and is widely used in various construction projects. There are many similar water reducers, such as naphthalene water reducers and aliphatic water reducers. However, compared with the above two types of water-reducing agent, polycarboxylic acid water-reducing agent has the following characteristics:
The first is that the polycarboxylic acid water reducer has good slump retention. In a short period of time, the slump basically causes no loss or the loss is relatively small. The effect is retained to the greatest extent.
The second advantage is that under the same fluidity, the Polycarboxylate acid superplasticizer has a relatively small effect on the setting time of cement, and can solve the problems of water reduction, air entrainment, and retardation to the greatest extent.
In addition, Polycarboxylate acid superplasticizer is a high-performance water reducer, and its structure can be adjusted through molecules. It can also be used to manufacture well water machines with special properties, such as low temperature, high early strength, zero slump loss, shrinkage resistance, etc. A wide range of applications has also contributed to the popularity of this series of water-reducing agents.
The next advantage of Polycarboxylate acid superplasticizer is that it can reduce the cost to the greatest extent. Because he can use more frames or fly ash instead of cement. Let cheaper materials replace the role of cement. Greatly reduce costs. This is also one of the reasons why he is the best seller
In addition, the polycarboxylate alkali water agent is a relatively environmentally friendly method in the manufacturing process. It will not release some formaldehyde, naphthalene and other harmful substances, and will not pollute the environment. It can ensure that users can guarantee their own products to the utmost extent during use. healthy.
The above are the main advantages of Polycarboxylate acid superplasticizer. Next, I will introduce the main methods and precautions of the use of Polycarboxylate acid superplasticizer.
First of all, in the process of using polycarboxylic acid water-reducing agent, it is necessary to adjust the water consumption and sand rate according to the design requirements of the concrete through experiments to determine the slump, strength and setting of the mixture. Prevent data errors from occurring.
The second is that Polycarboxylate acid superplasticizer. are usually used in high-performance concrete, high-strength concrete, and high-flow concrete. Therefore, before use, it is necessary to select the raw materials according to the relevant technical specifications, determine the appropriate mixing process, and obtain a certain amount of experimental data. When the fluidity of stone concrete meets the requirements of construction, the strength of concrete has a certain rich coefficient.
Finally, in the process of using the water reducing agent, it can be stirred with water, but after the water is stirred, the effect will be better.
The above is the main content of this introduction. Welcome all interested friends to come to consult!
