Method 1: Enhance technical level, support item high quality, and strengthen technological reserves:

According to the study, only a few producers of polycarboxylic acid water reducer items in my country are individually established, and most other producers introduce technology from college research study establishments or study institutes or directly introduce modern technology from various other firms to begin manufacturing. As a result of the limited technical toughness of the producers themselves, they do not have a deep understanding of the polycarboxylic acid water reducer modern technology they create, and it is hard to adapt to different modifications in basic materials and procedures, and there is no other way to talk about the security of item top quality. Therefore, it is recommended that polycarboxylic acid water-reducing representative manufacturers proactively cooperate with universities and study institutes to completely recognize the different variables influencing the efficiency of polycarboxylic acid water-reducing agent products, readjust the synthesis procedure parameters in a prompt way to maintain product top quality, and strengthen technological reserves with joint or independent r & d to adjust to market need. Additionally, the very early launch of polycarboxylic acid water-reducing agent raw material requirements and the stability of polycarboxylic acid water-reducing representative basic material prices are additionally extremely crucial to make sure the security of polycarboxylic acid water-reducing agent product performance.

Approach 2: Belief in test results as opposed to product specs

Some items that are amazing in the water-reducing representative specs, or even products with superb test results, may not be suitable for a certain task. On the contrary, some products might satisfy the requirements of concrete material prep work for a particular task despite the fact that the test results are not really impressive. Furthermore, because of changes in resources, the examination results during task bidding process can not represent the real implementation of the project. GB50119-2003 “Technical Specifications for Application of Concrete Admixtures” “2.1.4” clearly stipulates: The raw materials made use of in concrete with admixtures, such as cement, sand, stone, admixtures, and admixtures, shall adhere to the provisions of the relevant national standards effective; when trial-mixing concrete with admixtures, the raw materials made use of in the task will be used, and the test products shall be identified according to the design and construction needs. The test conditions shall coincide as the construction problems. When the raw products made use of in the job or the concrete efficiency demands alter, the trial-mixing test shall be conducted once again.

Approach 3: Avoid call in between polycarboxylic acid water reducers and iron products

For polycarboxylic acid water reducer suppliers and providers, special manufacturing equipment and production lines will be made use of to synthesize and intensify polycarboxylic acid water reducers, and polycarboxylic acid water reducers will not be synthesized or compounded using the same production line as various other water reducers. Furthermore, the transportation and storage of polycarboxylic acid water reducers shall not utilize iron materials (except stainless steel) however plastic, glass and other materials. Call with iron sometimes creates changes in the efficiency of polycarboxylic acid water reducers.

Method 4: Resolutely prevent mixing other types of admixtures

It is purely prohibited to blend other water reducers or other types of admixtures. There are two definitions. Initially, the compounding of polycarboxylic acid water reducers (such as with lignin sulfonate, air entrainment, defoaming, slowing down and various other components) can only be performed by admixture producers or suppliers. The individual of the water reducer, that is, the concrete preparer, only needs to examine and save its relevant efficiency. Nothing else components might be intensified in it, neither might various other components be blended in it as a result of carelessness. It is definitely prohibited to make use of pumps and metering devices for pumping and metering other admixtures without cleansing. Another meaning is that concrete mixing devices, transportation lorries, and pumping tools are best made use of for concrete blended with polycarboxylic acid water reducers. When sharing blending tools, transport vehicles and pumping devices, these devices needs to be thoroughly cleaned up before they can be utilized for concrete mixed with other kinds of admixtures, and vice versa.

Method 5: Strictly gauge the water reducer and mix water

When preparing concrete mixes with polycarboxylic acid water reducers, the optimum water reducer dose and water consumption figured out by the research laboratory should be strictly determined. Do not boost the water reducer dose or water intake at will certainly to stay clear of negative sensations such as segregation, blood loss, setting, and enhanced air material in the combined concrete, which will certainly impact the regular pumping building and putting high quality of the concrete.

The moisture contained in the raw products sand and rock accumulations need to be accurately determined and deducted from the total water usage to prevent damaging consequences triggered by inaccurate discovery of the wetness contained in the sand and rock accumulations.

Approach 6: Correctly deal with the compatibility problem of polycarboxylic acid water reducers and cement/admixtures

The compatibility problem of admixtures and cement/admixtures has a lengthy background. Over the years, the flexibility study work with naphthalene-based high-efficiency water-reducing agents and their compound products has attained great outcomes:

With the hard work of scientists, concrete preparers, admixture manufacturers, cement and admixture makers, concrete manufacturers and supervisors have collectively recognized this problem, altering the circumstance in which admixture producers and suppliers have constantly assumed all responsibilities.The conflict of admixtures and cement/admixtures is attributed to several influencing factors, and comprehensive research study has been carried out on their influencing laws. A collection of efficient remedies have been explored for the particular incompatibility in between admixtures and cement/admixtures.

Technique 7: Purely regulate the vibration radius and resonance time

Because the depression of concrete prepared with polycarboxylic acid-based water-reducing agents is typically big and the viscosity of the blend is low, the resonance radius and resonance time after the concrete mixture is put ought to be established via experiments or need to be directed by professionals. Suppose the vibration radius is too little or the vibration time is also long. Because case, it is easy to create structural flaws such as a significant decrease in concrete air content and major stratification of the accumulated stage and paste phase.

Technique 8: Strengthen preliminary upkeep and protect against cracking.

On any kind of event, for any type of concrete mix, initial and later maintenance after pouring is extremely essential.

Polycarboxylic acid water reducer has little result on the shrinkage performance of concrete; in other words, the addition of polycarboxylic acid water reducer does not exceedingly enhance the contraction of concrete, which does not mean that the concrete with polycarboxylic acid water reducer can kick back and even cancel the maintenance.

Like concrete with other admixtures, the secondary surface denigration, film covering or spraying of concrete with polycarboxylic acid water reducer after pouring and vibration is really reliable in preventing its plastic shrinking cracks. Constant 7d or 14d hydrating maintenance is not only essential for the regular development of concrete strength however likewise an assurance to prevent its drying contraction fractures.

In order to improve the fracture resistance of concrete with polycarboxylic acid, it is also necessary to include a particular amount of fiber, and this sort of concrete still needs excellent wet treating to make sure that the framework does not crack.

Method 9: Construction and monitoring units ought to work carefully with concrete preparation and admixture suppliers

In the task, it is inescapable to experience numerous technological troubles, technological conflicts and even problems and disputes brought on by design crashes. The supreme objective of all parties involved in the project is to ensure the smooth progression of the project and the high quality of the task. The background of polycarboxylic acid water reducers in manufacturing and application in actual tasks is really short, and the built up design experience might be much better. It is simple to run into application troubles and also lead to engineering mishaps at this time, the construction system or administration unit requires to function very closely with the concrete prep work, polycarboxylic acid water reducer manufacturing and supply, and cement/admixture manufacturing and supply from a technical point of view and conduct extensive analysis to suggest efficient services.
