What is PC based polycarboxylate superplasticizer? 10

There is a difference, the superplasticizer contains a polycarboxylate superplasticizer, and the size of the concept is different.

Superplasticizer is a large category, which includes lignin-based superplasticizer, naphthalene superplasticizer, melamine superplasticizer, polycarboxylate superplasticizer, etc., polycarboxylate superplasticizer is one of the subcategories.

At present, the most widely used is polycarboxylate superplasticizer. The water reduction rate of polycarboxylate superplasticizer can be as high as 35%, which can effectively improve the workability of concrete, improve the early strength of concrete, and increase the slump holding time of concrete.

Polycarboxylate superplasticizer belongs to a kind of superplasticizer, which includes aliphatic superplasticizer, naphthalene superplasticizer, sulfamate and many other types

They are all superplasticizers, different raw materials, different processes, the effect of superplasticizers is slightly different, the cost of melamine superplasticizer is higher, and the superplasticizer is easy to leak water.

Questions. Can melamine superplasticizer be mixed with polycarboxylate superplasticizer?

No. It's better not to.

Questions. What are the adverse reactions?

Polypeptide superplasticizer is different from traditional superplasticizer, the dosage is small, efficient, temperature sensitive, dosage sensitive, material sensitive, and the same formula of polypeptide superplasticizer production in the working characteristics of each batch of polypeptide may have a lot of differences, the original superplasticizer is almost a concrete can not be mixed.

Questions. There is no reaction between the two.

Yes, you can go to a small dose experiment by yourself, which is more intuitive.

Questions. What is used to increase fluidity with cement-based self-leveling, and several chemical names are recommended.

1. Increase the collapse of concrete, generally 140-180, you can increase it to 200 and above. 2. Improve the mix ratio, increase some powder without affecting the strength, and of course, the amount of cement will also change. 3. Improve grading, reduce the coarse aggregate by one grade or increase the use of small granules.

4. Use admixtures. It should be noted that the increase in fluidity will reduce the strength and performance of concrete, so the amount of cement should generally be adjusted. Therefore, the adjustment of liquidity should be done in moderation and not blindly increased.

Questions. Zuo Yi].

There are many types of water reducers.

Including naphthalene, aliphatic, sulfonated melamine.

Polycarboxylic acid is one of them.

Now polycarboxylic acid superplasticizers are generally used.

Comparatively speaking, the performance is superior.

Better value for money.

Summary. Polycarboxylic acid high-performance superplasticizer is a kind of superplasticizer, and the water reduction rate is usually required to reach more than 25%. Polycarboxylic acid high-performance superplasticizer:

It is a series of superplasticizers composed of unsaturated monomers containing carboxyl groups and other monomers that copolymerize to make concrete have excellent properties in water reduction, collapse retention, reinforcement, shrinkage and environmental protection. (According to the industry standard JG T223-2007 "Polycarboxylic Acid High-performance Superplasticizer") construction industry.

Polycarboxylic acid high-performance superplasticizer is a kind of superplasticizer, and the dry rate of Bi Xiandong water reducer is usually required to reach more than 25%. Polycarboxylic acid high-performance superplasticizer: a series of superplasticizers composed of unsaturated monomers containing carboxyl groups and other monomers copolymerized, so that concrete has excellent properties in water reduction, collapse, reinforcement, collection, transportation and burial and environmental protection.

Polycarboxylate superplasticizer belongs to the chemical industry? Hmmm.

Hello, dear <>

According to the questions you provide, we will find the following: Polycarboxylate superplasticizer is a high molecular weight polymer, and its chemical properties mainly include the following aspects: 1

Physical properties: Polycarboxylate superplasticizer is a linear polymer with repeating units in its molecular structure. Its molecular weight distribution is relatively wide and can be in a variety of forms, such as high density, medium density and low density.

2.Chemical reactivity: Polycarboxylate superplasticizer molecules contain hydroxyl and carboxyl functional groups that can react chemically with other molecules.

However, its reactivity with metals is limited due to the limitations of its chemical structure. 3.Biodegradability:

Polycarboxylate superplasticizer is easily hydrolyzed by microorganisms in the natural environment, and its biodegradable products can be further converted into water and carbon dioxide. The chemical properties of polycarboxylate superplasticizer mainly involve physics, chemical reactivity and biodegradability.

Polycarboxylate superplasticizer, what can be flushed and solidified.

The solid content of polycarboxylate superplasticizer refers to the solid content in the liquid. The test method for solid content is generally used routinely, and this method is suitable for determining the percentage of solids of concrete admixtures. Instrument A

Analytical balance (weighing 200g, graduation value 0?).1mg);b.Blower Wind Heating Constant Temperature Drying Oven (1 200 ); c.

Weighing flasks with caps (25 65mm); d.Dryer (filled with color-changing silica gel). 1. Test steps (1) Put the clean weighing flask with lid into the oven, bake at 100 105 for 30min, take it out and put it in the dryer, cool it for 30min and weigh it, and repeat the above steps until constant weight.

2) Load the test sample into a weighing flask that has a constant weight, and close the lid to weigh out the total mass of the sample and the weighing flask as m1. (3) Put the weighing flask containing the sample into the oven, open the cap, raise the temperature to 100 105 to dry, cover the lid and place it in the dryer to cool for 30min before weighing, repeat the above steps until the constant weight, and its mass is m2.
