Is concrete segregation difficult to solve? Jiangsu concrete anti-segregation agent. Concrete anti-segregation agent, this product is a water-based polymer composition, does not entrain air, does not retard setting, does not contain chloride ions, and has no negative impact on strength. Scope of application: Concrete with large slump and high segregation, or concrete in special construction locations.
Application scope: Concrete with large slump and high segregation, or concrete in special construction parts.
Usage:
1. Adding 0.5kg to 1 cubic meter of concrete can reduce the slump by 3-5cm. A 5kg barrel of conditioner can handle 10 cubic meters of material. For 1 cubic meter of severely segregated material, add 1kg.
2. Add the powder conditioner cup (200g full) to the inlet of the mixer truck, rotate it at high speed for 3-5 minutes, and observe the material condition.
3. This product is a water-based polymer composition that does not entrain air, does not retard the setting, does not contain chloride ions, and has no negative impact on strength.
Due to the above-mentioned objective reasons, the fineness modulus of manufactured sand is relatively large, with more particles at both ends and fewer particles in the middle. The shape of the particles is rough and sharp, with many edges and corners, and many needles and flakes, resulting in poor cohesion of the prepared concrete, and The workability is not good, and the amount of powder glue materials (cement, coal ash, mineral powder, etc.) is large. The wrapping property is not good, even bleeding, slurry, sand and gravel slurry are separated, the water retention is poor, the amount of admixture is large, the concrete is easy to separate coarse and fine aggregates during pumping or unloading, and it is easy to block the pump and pipes, etc.** situation. When configuring machine-made sand concrete, in addition to controlling the coarse and fine aggregates and the fineness gradation of different aggregates in the concrete mixing station, in addition to adding conventional water-reducing, slumping-preserving and retarding additives, , you can artificially add Pian Technology's concrete conditioner.
During the actual production and operation of the concrete mixing station, due to fluctuations in the water content of sand and gravel or water-reducing agent measurement, material fluctuations, the construction site must deal with factors such as the speed of delivery, and even the sensitivity of admixtures to materials, etc. Under such circumstances, the slump of the concrete at the time of departure is too large (more than 240mm), resulting in concrete segregation, sand, stone, and slurry separation. If the receiving site does not cooperate and supervision and acceptance are stricter, there will be a loss of time and At the critical moment of diesel, labor and other expenses, what can help the site is a kind of anti-segregation conditioner made by Pian Technology. The core of the technology is to absorb the excess free moisture of the concrete and appropriately reduce the slump of the concrete on site to a suitable range. For example, the dosage is 0.5-1kg added to 1m3 of concrete, the powder is added to the mixer truck, and rotated at high speed for 3-5 minutes to allow the Pian Technology anti-segregation conditioner to fully mix and absorb water without affecting the strength and setting time of the concrete. As an additional option to solve on-site vehicle withdrawal.
