Method 1: Enhance technological degree, stabilize item top quality, and strengthen technical gets:
According to the study, just a few suppliers of polycarboxylic acid water reducer products in my country are independently developed, and most various other suppliers introduce modern technology from college study institutions or research study institutes or straight introduce technology from various other firms to start production. Because of the minimal technological strength of the suppliers themselves, they do not have a deep understanding of the polycarboxylic acid water reducer technology they generate, and it is challenging to adapt to various changes in raw materials and processes, and there is no other way to discuss the security of item high quality. For that reason, it is advised that polycarboxylic acid water-reducing agent producers proactively cooperate with colleges and study institutes to completely comprehend the different elements affecting the efficiency of polycarboxylic acid water-reducing agent items, change the synthesis process parameters in a timely fashion to maintain product quality, and enhance technological reserves via joint or independent r & d to adapt to market need. On top of that, the very early release of polycarboxylic acid water-reducing agent raw material standards and the stability of polycarboxylic acid water-reducing agent raw material prices are additionally very important to ensure the stability of polycarboxylic acid water-reducing agent item efficiency.
Method 2: Belief in examination results rather than item specifications
Some products that are remarkable in the water-reducing representative specifications, or perhaps products with excellent test outcomes, might not appropriate for a specific task. However, some items may fulfill the requirements of concrete material prep work for a certain project although the test outcomes are not very superior. On top of that, due to changes in raw materials, the examination results during job bidding process can not represent the actual application of the project. GB50119-2003 “Technical Specs for Application of Concrete Admixtures” “2.1.4” plainly stipulates: The raw materials used in concrete with admixtures, such as concrete, sand, stone, admixtures, and admixtures, shall comply with the arrangements of the pertinent nationwide standards effective; when trial-mixing concrete with admixtures, the raw materials utilized in the project shall be made use of, and the examination things will be established according to the style and building requirements. The test conditions shall coincide as the construction conditions. When the raw materials used in the project or the concrete efficiency needs change, the trial-mixing examination will be performed once more.

Method 3: Stay clear of contact between polycarboxylic acid water reducers and iron materials
For polycarboxylic acid water reducer manufacturers and distributors, unique manufacturing equipment and assembly line will be utilized to manufacture and intensify polycarboxylic acid water reducers, and polycarboxylic acid water reducers shall not be manufactured or compounded using the very same production line as various other water reducers. Furthermore, the transportation and storage space of polycarboxylic acid water reducers shall not use iron products (except stainless-steel) yet plastic, glass and other products. Contact with iron in some cases triggers adjustments in the efficiency of polycarboxylic acid water reducers.
Approach 4: Resolutely stay clear of blending other kinds of admixtures
It is purely forbidden to blend various other water reducers or various other types of admixtures. There are 2 meanings. Initially, the compounding of polycarboxylic acid water reducers (such as with lignin sulfonate, air entrainment, defoaming, retarding and other elements) can just be executed by admixture suppliers or providers. The individual of the water reducer, that is, the concrete preparer, just needs to evaluate and store its appropriate performance. No other elements might be intensified in it, nor may various other components be blended in it due to oversight. It is absolutely forbidden to utilize pumps and metering equipment for pumping and metering various other admixtures without cleansing. Another meaning is that concrete mixing devices, transportation lorries, and pumping tools are best used for concrete combined with polycarboxylic acid water reducers. When sharing blending devices, transport cars and pumping devices, these devices needs to be extensively cleansed prior to they can be made use of for concrete mixed with other types of admixtures, and vice versa.
Approach 5: Purely measure the water reducer and mix water
When preparing concrete mixes with polycarboxylic acid water reducers, the optimal water reducer dosage and water usage established by the lab should be purely gauged. Do not enhance the water reducer dosage or water usage at will certainly to avoid damaging sensations such as partition, blood loss, hardening, and increased air content in the mixed concrete, which will certainly impact the regular pumping building and construction and putting high quality of the concrete.
The dampness had in the raw products sand and rock aggregates must be precisely determined and subtracted from the overall water intake to stop negative effects brought on by inaccurate discovery of the dampness included in the sand and rock aggregates.

Method 6: Correctly face the compatibility trouble of polycarboxylic acid water reducers and cement/admixtures
The compatibility trouble of admixtures and cement/admixtures has a lengthy background. For many years, the adaptability research deal with naphthalene-based high-efficiency water-reducing agents and their compound items has achieved great results:
Through the hard work of scientists, concrete preparers, admixture manufacturers, concrete and admixture suppliers, concrete erectors and managers have actually jointly identified this trouble, changing the circumstance in which admixture suppliers and suppliers have always presumed all responsibilities.The conflict of admixtures and cement/admixtures is credited to several influencing factors, and in-depth study has actually been carried out on their influencing regulations. A collection of reliable options have been checked out for the specific conflict in between admixtures and cement/admixtures.
Approach 7: Purely control the vibration distance and resonance time
Since the slump of concrete prepared with polycarboxylic acid-based water-reducing agents is normally big and the thickness of the mix is low, the resonance distance and resonance time after the concrete blend is poured need to be identified via experiments or must be assisted by professionals. Expect the vibration radius is too tiny or the resonance time is as well long. In that situation, it is easy to create architectural flaws such as a major decrease in concrete air web content and significant stratification of the accumulated stage and paste phase.
Technique 8: Reinforce initial maintenance and prevent cracking.
On any kind of event, for any concrete mix, first and later upkeep after pouring is extremely crucial.
Polycarboxylic acid water reducer has little effect on the shrinking performance of concrete; simply put, the enhancement of polycarboxylic acid water reducer does not excessively increase the shrinkage 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 second surface area smearing, movie covering or spraying of concrete with polycarboxylic acid water reducer after putting and vibration is really effective in stopping its plastic shrinking fractures. Continuous 7d or 14d moisturizing upkeep is not just necessary for the regular growth of concrete toughness but likewise a guarantee to stop its drying shrinking splits.

In order to boost the crack resistance of concrete with polycarboxylic acid, it is additionally essential to add a specific quantity of fiber, and this type of concrete still requires great damp healing to ensure that the structure does not split.
Technique 9: Construction and management units need to function carefully with concrete prep work and admixture vendors
In the task, it is inescapable to run into various technical difficulties, technological disputes and also disputes and disputes triggered by design crashes. The ultimate objective of all celebrations involved in the project is to ensure the smooth progression of the job and the top quality of the job. The history of polycarboxylic acid water reducers in production and application in real jobs is really short, and the accumulated engineering experience might be far better. It is very easy to come across application issues and even cause engineering mishaps right now, the building device or administration unit requires to function carefully with the concrete prep work, polycarboxylic acid water reducer manufacturing and supply, and cement/admixture production and supply from a technical viewpoint and conduct thorough evaluation to propose reliable solutions.
