Technique 1: Improve technological degree, maintain item top quality, and enhance technical books:
According to the survey, just a couple of manufacturers of polycarboxylic acid water reducer items in my country are separately developed, and the majority of various other manufacturers introduce modern technology from university study institutions or research institutes or straight present technology from various other business to start manufacturing. Due to the minimal technological toughness of the manufacturers themselves, they do not have a deep understanding of the polycarboxylic acid water reducer modern technology they produce, and it is challenging to adjust to numerous modifications in basic materials and procedures, and there is no other way to discuss the security of product top quality. Therefore, it is recommended that polycarboxylic acid water-reducing agent makers proactively accept colleges and study institutes to completely recognize the different factors affecting the efficiency of polycarboxylic acid water-reducing agent items, readjust the synthesis procedure specifications in a timely way to maintain product high quality, and strengthen technological reserves through joint or independent r & d to adjust to market need. Furthermore, the early launch of polycarboxylic acid water-reducing representative resources standards and the stability of polycarboxylic acid water-reducing representative resources rates are also very essential to guarantee the security of polycarboxylic acid water-reducing representative product efficiency.
Technique 2: Idea in examination results instead of item specs
Some products that are fantastic in the water-reducing representative requirements, or even products with superb test outcomes, might not appropriate for a details project. However, some items may meet the demands of concrete product preparation for a specific job despite the fact that the examination results are not extremely outstanding. On top of that, as a result of changes in raw materials, the test results during job bidding process can not stand for the actual application of the task. GB50119-2003 “Technical Specifications for Application of Concrete Admixtures” “2.1.4” plainly states: The raw materials made use of in concrete with admixtures, such as cement, sand, rock, admixtures, and admixtures, shall adhere to the stipulations of the pertinent nationwide standards active; when trial-mixing concrete with admixtures, the raw materials made use of in the project will be utilized, and the examination things will be identified according to the layout and building needs. The examination problems shall be the same as the building and construction problems. When the raw materials made use of in the project or the concrete performance needs alter, the trial-mixing examination shall be conducted once again.

Method 3: Stay clear of call between polycarboxylic acid water reducers and iron materials
For polycarboxylic acid water reducer manufacturers and suppliers, special production devices and assembly line will be utilized to synthesize and intensify polycarboxylic acid water reducers, and polycarboxylic acid water reducers shall not be synthesized or intensified utilizing the exact same production line as various other water reducers. Additionally, the transport and storage of polycarboxylic acid water reducers shall not use iron products (except stainless-steel) however plastic, glass and various other products. Call with iron often triggers modifications in the efficiency of polycarboxylic acid water reducers.
Method 4: Resolutely prevent blending various other types of admixtures
It is purely restricted to mix various other water reducers or various other kinds of admixtures. There are two meanings. First, the compounding of polycarboxylic acid water reducers (such as with lignin sulfonate, air entrainment, defoaming, hampering and various other parts) can only be carried out by admixture makers or providers. The user of the water reducer, that is, the concrete preparer, only requires to evaluate and keep its relevant performance. Nothing else parts may be worsened in it, neither may various other elements be mixed in it as a result of negligence. It is definitely forbidden to make use of pumps and metering devices for pumping and metering various other admixtures without cleansing. An additional definition is that concrete mixing equipment, transportation vehicles, and pumping tools are best used for concrete blended with polycarboxylic acid water reducers. When sharing mixing equipment, transportation lorries and pumping devices, these devices has to be extensively cleaned prior to they can be utilized for concrete blended with other types of admixtures, and the other way around.
Approach 5: Strictly gauge the water reducer and mix water
When preparing concrete combinations with polycarboxylic acid water reducers, the optimum water reducer dose and water consumption identified by the lab ought to be strictly gauged. Do not enhance the water reducer dose or water intake at will to stay clear of damaging sensations such as segregation, bleeding, hardening, and raised air content in the mixed concrete, which will affect the regular pumping construction and pouring quality of the concrete.
The moisture included in the raw materials sand and rock accumulations have to be accurately determined and deducted from the overall water intake to prevent unfavorable repercussions brought on by imprecise discovery of the dampness included in the sand and rock aggregates.

Approach 6: Properly deal with the compatibility issue of polycarboxylic acid water reducers and cement/admixtures
The compatibility issue of admixtures and cement/admixtures has a long history. Throughout the years, the adaptability research work with naphthalene-based high-efficiency water-reducing agents and their substance products has actually achieved excellent outcomes:
With the effort of researchers, concrete preparers, admixture suppliers, cement and admixture makers, concrete fitters and managers have collectively identified this issue, altering the circumstance in which admixture manufacturers and providers have constantly thought all responsibilities.The incompatibility of admixtures and cement/admixtures is attributed to lots of influencing aspects, and comprehensive research has actually been accomplished on their affecting laws. A series of efficient solutions have actually been explored for the specific incompatibility between admixtures and cement/admixtures.
Method 7: Purely control the resonance radius and vibration time
Considering that the depression of concrete prepared with polycarboxylic acid-based water-reducing agents is normally huge and the viscosity of the blend is reduced, the resonance span and vibration time after the concrete combination is put ought to be determined through experiments or should be directed by specialists. Mean the vibration span is too small or the vibration time is also long. In that situation, it is easy to trigger structural defects such as a significant reduction in concrete air material and major stratification of the accumulated stage and paste stage.
Technique 8: Enhance first upkeep and protect against cracking.
On any event, for any concrete blend, preliminary and later upkeep after putting is extremely important.
Polycarboxylic acid water reducer has little result on the shrinkage performance of concrete; to put it simply, 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 unwind or perhaps cancel the upkeep.
Like concrete with other admixtures, the additional surface area denigration, movie covering or splashing of concrete with polycarboxylic acid water reducer after putting and resonance is extremely effective in stopping its plastic shrinkage splits. Continuous 7d or 14d moisturizing upkeep is not only needed for the regular growth of concrete strength yet likewise a warranty to prevent its drying out shrinkage cracks.

In order to boost the fracture resistance of concrete with polycarboxylic acid, it is likewise essential to add a specific amount of fiber, and this kind of concrete still needs excellent damp treating to make certain that the structure does not crack.
Technique 9: Building and construction and administration systems must work carefully with concrete preparation and admixture providers
In the task, it is unpreventable to encounter various technological difficulties, technical conflicts and also disputes and disputes caused by engineering accidents. The best goal of all events involved in the task is to make sure the smooth progress of the project and the high quality of the task. The background of polycarboxylic acid water reducers in production and application in real jobs is very short, and the collected engineering experience could be far better. It is very easy to come across application issues and even bring about engineering accidents at this time, the building and construction system or management device requires to function carefully with the concrete preparation, polycarboxylic acid water reducer production and supply, and cement/admixture production and supply from a technological point of view and conduct comprehensive evaluation to propose effective options.
