Compared with traditional superplasticizers such as naphthalene-based superplasticizers, superplasticizer powder for concrete have many unique technical performance advantages:
It is precisely because of the above performance advantages that polycarboxylate-based high-performance superplasticizers have begun to attract extensive attention in the domestic engineering community in recent years. Many important projects have used this new type of superplasticizer in large quantities, such as Shanghai Maglev, Shanghai World Financial Center, Hangzhou Bay Bridge, Donghai Bridge, Beijing Yintai Building, Beijing Capital International Airport Expansion Project, etc.
It is foreseeable that due to the above-mentioned many unique performance advantages, polycarboxylic acid-based high-performance superplasticizers will quickly become the mainstream products in the superplasticizer market.
Because superplasticizer powder for concrete high-performance water reducers are mostly in liquid state, the milling process is complicated and the production process is unsafe. Therefore, the market is mostly based on the body to sell.
In the past, due to the improvement of technology and the improvement of the milling process, polycarboxylic acid-based high-performance water reducers in powder form have become relatively common. In contrast, products in powder form provide a lot of convenience from transportation to customer use. Since then, powder has formed the development trend of such products.
The recommended dosage of water reducer for concrete is: 0.1~0.25% of the cement dosage.
The water reducing agent is a powder with polycarboxylate as the main component. Its solid content is about 98%. The normal dosage is 0.12%-0.3%. When the dosage is only 0.06%, it has a water reducing rate of 12%. And the strength increase of 23% has surpassed the effect of commercially available ordinary pumping agents.
When the dosage is 0.1%, the performance exceeds the level of general naphthalene series and pyrimidine superplasticizers. However, when the dosage is lower than 0.14%, the excellent performance of the working performance is not obvious. When the dosage reaches more than 0.20%, the working performance and pumping performance of concrete are improved to a very good level.
Therefore, the recommended optimal dosage is 0.12-0.24%; when configuring high-grade, large-volume fly ash/slag micropowder concrete and concrete with special requirements, the dosage can be enlarged to more than 0.3%, but generally it should not exceed 0.5 %, experiments show that when the dosage is enlarged to 0.5%, the concrete does not produce cohesion and aggregate slurry separation (segregation) phenomenon, the water reduction rate still increases, but the gas content increases, the setting is delayed, and the strength decreases.
