Approach 1: Boost technical level, support product quality, and enhance technical reserves:
According to the survey, just a couple of makers of polycarboxylic acid water reducer items in my country are independently developed, and the majority of other makers present technology from university study establishments or research institutes or directly present innovation from other business to start production. Because of the minimal technological toughness of the manufacturers themselves, they do not have a deep understanding of the polycarboxylic acid water reducer modern technology they create, and it is hard to adjust to numerous changes in resources and processes, and there is no chance to speak about the stability of item quality. As a result, it is advised that polycarboxylic acid water-reducing representative manufacturers proactively accept colleges and research study institutes to totally recognize the numerous elements impacting the efficiency of polycarboxylic acid water-reducing agent items, readjust the synthesis process parameters in a prompt way to support item top quality, and enhance technological reserves via joint or independent r & d to adjust to market demand. Additionally, the early release of polycarboxylic acid water-reducing representative basic material criteria and the security of polycarboxylic acid water-reducing agent resources rates are additionally very crucial to make sure the stability of polycarboxylic acid water-reducing agent item performance.
Technique 2: Idea in examination results rather than item requirements
Some items that are remarkable in the water-reducing agent requirements, or even items with excellent test results, might not be suitable for a details job. However, some products might meet the requirements of concrete material prep work for a specific job even though the examination results are not extremely exceptional. Additionally, due to modifications in basic materials, the examination results throughout project bidding can not represent the real implementation of the project. GB50119-2003 “Technical Specs for Application of Concrete Admixtures” “2.1.4” plainly states: The raw products used in concrete with admixtures, such as concrete, sand, rock, admixtures, and admixtures, will adhere to the arrangements of the relevant nationwide standards in force; when trial-mixing concrete with admixtures, the raw materials made use of in the job shall be utilized, and the test items will be identified according to the style and building demands. The test problems shall coincide as the building and construction conditions. When the raw materials used in the job or the concrete efficiency needs change, the trial-mixing examination will be carried out once again.

Approach 3: Stay clear of call between polycarboxylic acid water reducers and iron materials
For polycarboxylic acid water reducer producers and distributors, unique production devices and production lines will be used to synthesize and intensify polycarboxylic acid water reducers, and polycarboxylic acid water reducers will not be manufactured or worsened making use of the exact same production line as various other water reducers. Furthermore, the transportation and storage of polycarboxylic acid water reducers shall not make use of iron materials (except stainless-steel) however plastic, glass and various other products. Call with iron sometimes triggers modifications in the efficiency of polycarboxylic acid water reducers.
Technique 4: Resolutely stay clear of blending various other sorts of admixtures
It is strictly forbidden to blend various other water reducers or other kinds of admixtures. There are two meanings. Initially, the compounding of polycarboxylic acid water reducers (such as with lignin sulfonate, air entrainment, defoaming, hampering and other components) can only be performed by admixture makers or suppliers. The user of the water reducer, that is, the concrete preparer, only needs to examine and save its relevant efficiency. Nothing else parts may be compounded in it, neither might other components be mixed in it because of negligence. It is absolutely prohibited to utilize pumps and metering devices for pumping and metering various other admixtures without cleaning. An additional meaning is that concrete mixing tools, transport automobiles, and pumping equipment are best made use of for concrete mixed with polycarboxylic acid water reducers. When sharing blending devices, transportation vehicles and pumping tools, these devices needs to be thoroughly cleansed before they can be made use of for concrete mixed with various other kinds of admixtures, and the other way around.
Method 5: Purely measure the water reducer and mix water
When preparing concrete mixtures with polycarboxylic acid water reducers, the optimal water reducer dose and water usage established by the lab ought to be purely determined. Do not boost the water reducer dosage or water intake at will to prevent negative sensations such as partition, bleeding, solidifying, and enhanced air content in the mixed concrete, which will certainly affect the regular pumping building and putting high quality of the concrete.
The dampness consisted of in the raw materials sand and stone accumulations have to be accurately determined and deducted from the total water intake to prevent negative effects caused by inaccurate discovery of the wetness included in the sand and stone accumulations.

Method 6: Properly deal with the compatibility trouble of polycarboxylic acid water reducers and cement/admixtures
The compatibility problem of admixtures and cement/admixtures has a long history. For many years, the flexibility research study deal with naphthalene-based high-efficiency water-reducing agents and their substance products has accomplished good results:
Through the effort of researchers, concrete preparers, admixture suppliers, concrete and admixture suppliers, concrete manufacturers and supervisors have jointly acknowledged this problem, altering the circumstance in which admixture makers and distributors have actually constantly thought all responsibilities.The conflict of admixtures and cement/admixtures is credited to many influencing aspects, and in-depth research study has actually been performed on their affecting laws. A series of efficient remedies have actually been explored for the particular incompatibility between admixtures and cement/admixtures.
Approach 7: Purely regulate the resonance distance and resonance time
Given that the downturn of concrete prepared with polycarboxylic acid-based water-reducing representatives is generally large and the thickness of the mix is low, the resonance radius and resonance time after the concrete combination is poured ought to be established through experiments or need to be led by professionals. Mean the vibration distance is too tiny or the resonance time is too long. Because instance, it is simple to trigger structural flaws such as a serious decrease in concrete air web content and serious stratification of the aggregate stage and paste stage.
Technique 8: Reinforce preliminary maintenance and stop fracturing.
On any type of celebration, for any type of concrete blend, preliminary and later maintenance after pouring is really vital.
Polycarboxylic acid water reducer has little impact on the shrinking efficiency of concrete; simply put, the enhancement of polycarboxylic acid water reducer does not excessively raise the shrinkage of concrete, which does not indicate that the concrete with polycarboxylic acid water reducer can relax and even cancel the upkeep.
Like concrete with various other admixtures, the secondary surface area smearing, movie covering or splashing of concrete with polycarboxylic acid water reducer after putting and vibration is very efficient in preventing its plastic contraction fractures. Continuous 7d or 14d moisturizing maintenance is not only required for the typical growth of concrete strength however likewise an assurance to prevent its drying contraction cracks.

In order to enhance the crack resistance of concrete with polycarboxylic acid, it is additionally essential to add a certain quantity of fiber, and this sort of concrete still needs good damp healing to make sure that the framework does not break.
Approach 9: Construction and management devices ought to function carefully with concrete preparation and admixture suppliers
In the job, it is inescapable to run into different technical problems, technical disputes and also conflicts and disagreements caused by design accidents. The supreme objective of all events involved in the project is to make sure the smooth development of the job and the quality of the project. The background of polycarboxylic acid water reducers in production and application in real tasks is very brief, and the collected design experience can be far better. It is very easy to encounter application problems and even cause design crashes at this time, the building and construction device or administration device needs to function carefully with the concrete preparation, polycarboxylic acid water reducer manufacturing and supply, and cement/admixture manufacturing and supply from a technical perspective and conduct extensive evaluation to suggest efficient options.
