Approach 1: Improve technological level, support item quality, and strengthen technological books:

According to the study, only a few producers of polycarboxylic acid water reducer products in my country are individually developed, and a lot of various other producers introduce technology from college study institutions or study institutes or directly present technology from various other firms to begin manufacturing. Because of the restricted technical strength of the manufacturers themselves, they do not have a deep understanding of the polycarboxylic acid water reducer modern technology they generate, and it is hard to adapt to numerous adjustments in raw materials and procedures, and there is no way to speak about the security of product top quality. As a result, it is recommended that polycarboxylic acid water-reducing representative manufacturers actively accept universities and research study institutes to completely recognize the numerous factors affecting the performance of polycarboxylic acid water-reducing representative items, change the synthesis process parameters in a prompt way to stabilize product quality, and strengthen technical reserves through joint or independent research and development to adjust to market demand. In addition, the very early launch of polycarboxylic acid water-reducing representative basic material criteria and the stability of polycarboxylic acid water-reducing representative basic material rates are also very essential to guarantee the security of polycarboxylic acid water-reducing representative product efficiency.

Technique 2: Idea in examination outcomes instead of item specs

Some products that are impressive in the water-reducing representative requirements, or even items with outstanding test results, may not be suitable for a details job. On the contrary, some items may fulfill the needs of concrete material prep work for a specific task despite the fact that the test outcomes are not very impressive. On top of that, as a result of modifications in raw materials, the examination results throughout task bidding process can not represent the actual implementation of the project. GB50119-2003 “Technical Specifications for Application of Concrete Admixtures” “2.1.4” clearly states: The raw products utilized in concrete with admixtures, such as concrete, sand, stone, admixtures, and admixtures, shall adhere to the arrangements of the appropriate national criteria effective; when trial-mixing concrete with admixtures, the raw materials utilized in the task will be made use of, and the examination products shall be determined according to the layout and construction needs. The test conditions shall be the same as the building conditions. When the raw materials used in the project or the concrete performance demands transform, the trial-mixing test shall be carried out once more.

Approach 3: Stay clear of get in touch with in between polycarboxylic acid water reducers and iron products

For polycarboxylic acid water reducer manufacturers and providers, special production tools and production lines shall be used to manufacture and intensify polycarboxylic acid water reducers, and polycarboxylic acid water reducers shall not be synthesized or worsened using the same assembly line as other water reducers. Additionally, the transportation and storage of polycarboxylic acid water reducers shall not utilize iron materials (other than stainless-steel) but plastic, glass and various other materials. Call with iron sometimes creates adjustments in the efficiency of polycarboxylic acid water reducers.

Technique 4: Resolutely prevent blending various other kinds of admixtures

It is strictly prohibited to blend other water reducers or various other kinds of admixtures. There are two significances. First, the compounding of polycarboxylic acid water reducers (such as with lignin sulfonate, air entrainment, defoaming, hampering and other elements) can just be performed by admixture manufacturers or providers. The individual of the water reducer, that is, the concrete preparer, just requires to check and store its appropriate performance. No other parts might be worsened in it, nor may various other components be blended in it due to neglect. It is definitely forbidden to make use of pumps and metering tools for pumping and metering various other admixtures without cleaning. One more definition is that concrete mixing devices, transportation cars, and pumping tools are best used for concrete combined with polycarboxylic acid water reducers. When sharing mixing devices, transport vehicles and pumping tools, these equipment should be thoroughly cleansed prior to they can be used for concrete mixed with various other types of admixtures, and vice versa.

Method 5: Purely determine the water reducer and mix water

When preparing concrete blends with polycarboxylic acid water reducers, the ideal water reducer dose and water consumption established by the laboratory ought to be purely determined. Do not enhance the water reducer dosage or water intake at will to prevent adverse sensations such as partition, blood loss, setting, and increased air content in the blended concrete, which will affect the typical pumping building and putting high quality of the concrete.

The dampness contained in the raw products sand and stone aggregates must be precisely determined and deducted from the total water usage to avoid adverse consequences caused by unreliable detection of the moisture consisted of in the sand and rock accumulations.

Technique 6: Appropriately deal with the compatibility issue of polycarboxylic acid water reducers and cement/admixtures

The compatibility problem of admixtures and cement/admixtures has a long background. Over the years, the flexibility research study deal with naphthalene-based high-efficiency water-reducing representatives and their compound items has accomplished great results:

Through the effort of scientists, concrete preparers, admixture makers, concrete and admixture manufacturers, concrete erectors and managers have actually collectively recognized this trouble, altering the circumstance in which admixture suppliers and distributors have actually always presumed all responsibilities.The incompatibility of admixtures and cement/admixtures is credited to numerous influencing aspects, and extensive research has actually been carried out on their influencing laws. A series of effective remedies have been explored for the particular conflict in between admixtures and cement/admixtures.

Approach 7: Purely manage the resonance radius and resonance time

Considering that the downturn of concrete prepared with polycarboxylic acid-based water-reducing agents is normally huge and the viscosity of the mix is low, the vibration distance and vibration time after the concrete mixture is put should be figured out through experiments or should be directed by specialists. Intend the resonance distance is too small or the resonance time is also long. In that instance, it is simple to cause structural problems such as a serious decrease in concrete air material and major stratification of the aggregate phase and paste phase.

Technique 8: Reinforce initial upkeep and avoid fracturing.

On any celebration, for any kind of concrete mix, initial and later maintenance after putting is extremely crucial.

Polycarboxylic acid water reducer has little effect on the shrinkage performance of concrete; simply put, the enhancement of polycarboxylic acid water reducer does not excessively enhance the contraction of concrete, which does not suggest that the concrete with polycarboxylic acid water reducer can loosen up or perhaps terminate the upkeep.

Like concrete with other admixtures, the second surface smearing, film covering or spraying of concrete with polycarboxylic acid water reducer after pouring and resonance is really effective in avoiding its plastic contraction fractures. Constant 7d or 14d moisturizing maintenance is not just necessary for the typical growth of concrete toughness yet likewise a guarantee to stop its drying shrinkage cracks.

In order to improve the split resistance of concrete with polycarboxylic acid, it is likewise essential to add a particular amount of fiber, and this type of concrete still needs good damp curing to make certain that the framework does not crack.

Technique 9: Building and construction and management systems ought to work very closely with concrete preparation and admixture distributors

In the project, it is unpreventable to come across numerous technological troubles, technological disputes and also disputes and disputes caused by engineering accidents. The best goal of all parties associated with the project is to ensure the smooth progression of the job and the quality of the project. The history of polycarboxylic acid water reducers in manufacturing and application in real projects is really short, and the accumulated engineering experience can be better. It is very easy to experience application problems and also result in engineering accidents at this time, the building and construction device or administration device needs to work carefully with the concrete preparation, polycarboxylic acid water reducer production and supply, and cement/admixture manufacturing and supply from a technological point of view and carry out in-depth analysis to propose efficient remedies.
