Precautions during use of superplasticizer additive

Sweden is in talks with Turkey on joining NATO and looks forward to strengthening cooperation with Turkey in security and counter-terrorism, Swedish Prime Minister Anders Andersson said recently.  

Andersson held a joint press conference with visiting European Council President Michel in Stockholm on the same day. Andersson said Sweden is in dialogue with Turkey on joining the TREATY and looks forward to strengthening bilateral relations with Turkey, including cooperation in the areas of security and counter-terrorism. She said Sweden would study a number of issues raised by Turkey.  

Speaking at a news conference, Mr. Michel said he believed the Swedish government was taking positive action and taking the necessary steps to reach a solution.

Sweden and Finland formally submitted their applications to NATO Secretary-General Jens Stoltenberg a few days ago. According to protocol, NATO must admit new members by the "unanimous consent" of 30 members.

Turkish Foreign Minister Mevlut Cavusoglu said His country would agree to start NATO talks with Sweden and Finland only if they reach written agreements to stop supporting terrorism and lift restrictions on exporting defense equipment to Turkey, Turkish media reported.

Affected by the ever-changing international situation, the supply and prices of international bulk superplasticizer additive,pce superplasticizer are still very uncertain.

What is superplasticizer additive?

After the pce superplasticizer is added to the cement, the sodium aluminate and sodium carbonate in its main components react rapidly with the gypsum in the cement to form sodium sulfate in the alkaline solution, so that the gypsum loses its original retarding effect, so that the calcium aluminate mineral rapidly Hydration, and precipitate its hydration product crystals in the solution, so that the cement concrete rapidly coagulates.

Plasticizer and superplasticizer in concrete Notes:

1. Please do not add this product when mixing materials. Because stones and sand contain a lot of water, the concrete superplasticizer absorbs water in a short period of time and decomposes its quick-setting components, which affects the setting time, reduces the strength of concrete, and reduces the poor concrete quality. Effect.

2. Before use, a trial mix test should be carried out for the type of cement used in the project, and the dosage should be selected before it can be used in large quantities. Expired cement cannot be used, and cement that does not meet national standards cannot be used. The concrete water reducing agent is required to be properly stored to prevent the failure of moisture agglomeration. Strengthen early maintenance to ensure later strength. Strictly good water-cement ratio. For projects with water seepage and leakage, the dosage must be increased.

PCE superplasticizer is a kind of concrete admixture that can be mixed with water under the condition that the slump of concrete remains basically unchanged. Most of them are anionic surfactants, such as lignin sulfonate, naphthalene sulfonate formaldehyde polymer, etc. After adding to the concrete mix, it has a dispersing effect on the cement particles. Can its workability, unit water consumption, fluidity of concrete mixture; or unit cement consumption, saving cement.

Concrete superplasticizer additive is a kind of admixture that can meet the necessary unit water consumption in concrete, and can specify the consistency requirements and workability of concrete. When mixing concrete, adding an appropriate amount of water reducing agent can make the cement particles disperse evenly, and at the same time release the water wrapped by the cement particles, so that the water consumption of the concrete can be significantly increased.

1. Hydration efficiency, unit water consumption, water-cement ratio, concrete strength, concrete construction performance, saving cement consumption;

2. The workability of concrete that has not yet solidified to prevent the segregation of concrete components;

3. Impermeability, water-reducing and water-permeability, avoiding water leakage in concrete building structures, durability, chemical corrosion resistance;

4. The shrinkage rate of concrete solidification to prevent cracks in concrete components;

5. frost resistance, conducive to winter construction.
