Approach 1: Boost technological level, stabilize product quality, and reinforce technological books:

According to the survey, just a few producers of polycarboxylic acid water reducer products in my country are separately developed, and the majority of other manufacturers present technology from university research study organizations or research institutes or straight present technology from other companies to begin production. Because of the restricted technical toughness of the manufacturers themselves, they do not have a deep understanding of the polycarboxylic acid water reducer innovation they produce, and it is challenging to adapt to various modifications in basic materials and processes, and there is no other way to discuss the security of product top quality. For that reason, it is suggested that polycarboxylic acid water-reducing representative makers actively cooperate with universities and study institutes to totally understand the various aspects influencing the efficiency of polycarboxylic acid water-reducing representative products, readjust the synthesis procedure parameters in a prompt fashion to maintain item top quality, and enhance technological reserves with joint or independent r & d to adapt to market need. Furthermore, the very early release of polycarboxylic acid water-reducing agent resources standards and the security of polycarboxylic acid water-reducing agent basic material costs are also extremely essential to make sure the stability of polycarboxylic acid water-reducing agent item performance.

Method 2: Idea in examination results instead of product specifications

Some items that are incredible in the water-reducing agent requirements, or even items with superb test outcomes, may not appropriate for a particular project. As a matter of fact, some items may fulfill the requirements of concrete material preparation for a specific job despite the fact that the test outcomes are not very impressive. On top of that, due to adjustments in resources, the test results during job bidding process can not stand for the real implementation of the task. GB50119-2003 “Technical Specifications for Application of Concrete Admixtures” “2.1.4” plainly stipulates: The raw materials made use of in concrete with admixtures, such as cement, sand, stone, admixtures, and admixtures, will follow the stipulations of the appropriate national standards active; when trial-mixing concrete with admixtures, the raw materials used in the project shall be utilized, and the examination items shall be figured out according to the design and building needs. The test problems shall be the same as the building and construction conditions. When the raw materials made use of in the job or the concrete performance demands change, the trial-mixing test will be conducted once again.

Technique 3: Stay clear of contact between polycarboxylic acid water reducers and iron products

For polycarboxylic acid water reducer manufacturers and vendors, special manufacturing equipment and production lines shall be made use of to synthesize and worsen polycarboxylic acid water reducers, and polycarboxylic acid water reducers will not be manufactured or intensified making use of the very same production line as other water reducers. Furthermore, the transportation and storage space of polycarboxylic acid water reducers will not make use of iron materials (except stainless-steel) yet plastic, glass and various other materials. Contact with iron sometimes creates changes in the efficiency of polycarboxylic acid water reducers.

Method 4: Resolutely prevent mixing other kinds of admixtures

It is strictly restricted to mix other water reducers or other sorts of admixtures. There are two significances. Initially, the compounding of polycarboxylic acid water reducers (such as with lignin sulfonate, air entrainment, defoaming, slowing down and various other elements) can just be accomplished by admixture makers or providers. The customer of the water reducer, that is, the concrete preparer, just needs to evaluate and store its pertinent performance. No other parts may be worsened in it, nor might other parts be blended in it as a result of neglect. It is absolutely forbidden to use pumps and metering equipment for pumping and metering other admixtures without cleaning. An additional definition is that concrete mixing devices, transport cars, and pumping tools are best utilized for concrete mixed with polycarboxylic acid water reducers. When sharing blending tools, transportation automobiles and pumping tools, these equipment should be thoroughly cleansed before they can be used for concrete combined with other sorts of admixtures, and vice versa.

Technique 5: Purely measure the water reducer and mix water

When preparing concrete mixtures with polycarboxylic acid water reducers, the optimal water reducer dosage and water consumption established by the laboratory must be strictly measured. Do not raise the water reducer dose or water consumption at will to stay clear of negative phenomena such as segregation, bleeding, hardening, and boosted air content in the combined concrete, which will impact the typical pumping building and construction and pouring high quality of the concrete.

The wetness had in the raw products sand and rock accumulations have to be properly measured and subtracted from the total water usage to stop negative consequences brought on by incorrect discovery of the wetness had in the sand and rock aggregates.

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

The compatibility problem of admixtures and cement/admixtures has a long background. For many years, the flexibility research work on naphthalene-based high-efficiency water-reducing agents and their compound items has actually accomplished excellent outcomes:

Via the effort of scientists, concrete preparers, admixture manufacturers, concrete and admixture manufacturers, concrete constructors and managers have collectively acknowledged this trouble, changing the scenario in which admixture suppliers and providers have actually constantly thought all responsibilities.The conflict of admixtures and cement/admixtures is credited to several influencing variables, and extensive research study has been accomplished on their influencing legislations. A collection of efficient options have been explored for the certain conflict between admixtures and cement/admixtures.

Technique 7: Purely control the vibration span and resonance time

Because the downturn of concrete prepared with polycarboxylic acid-based water-reducing representatives is typically big and the viscosity of the mixture is low, the vibration span and vibration time after the concrete blend is poured must be determined via experiments or need to be led by specialists. Expect the vibration span is as well small or the vibration time is too long. In that situation, it is easy to create structural problems such as a major decline in concrete air web content and severe stratification of the accumulated phase and paste phase.

Method 8: Strengthen preliminary maintenance and avoid fracturing.

On any type of event, for any concrete blend, preliminary and later upkeep after putting is extremely essential.

Polycarboxylic acid water reducer has little result on the shrinkage efficiency of concrete; in other words, the addition of polycarboxylic acid water reducer does not exceedingly raise the shrinking of concrete, which does not suggest that the concrete with polycarboxylic acid water reducer can relax or even cancel the maintenance.

Like concrete with various other admixtures, the secondary surface smearing, film covering or spraying of concrete with polycarboxylic acid water reducer after pouring and vibration is extremely effective in avoiding its plastic shrinkage cracks. Continuous 7d or 14d hydrating upkeep is not only required for the typical development of concrete strength yet additionally a warranty to avoid its drying contraction cracks.

In order to boost the fracture resistance of concrete with polycarboxylic acid, it is likewise essential to include a certain amount of fiber, and this kind of concrete still requires good wet curing to ensure that the framework does not fracture.

Approach 9: Building and management units must work very closely with concrete prep work and admixture distributors

In the job, it is unpreventable to encounter various technical problems, technological disputes and also disputes and disagreements brought on by engineering mishaps. The best objective of all events associated with the job is to make sure the smooth progress of the job and the top quality of the project. The background of polycarboxylic acid water reducers in manufacturing and application in actual projects is really brief, and the gathered design experience could be far better. It is easy to come across application problems and even lead to design mishaps currently, the building system or monitoring 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 carry out extensive analysis to recommend efficient services.
