The use of commodity concrete water reducer, Polycarboxylate manufacturers to improve the workability of concrete while Polycarboxylate sales, has also become factors concrete workability fluctuations, which affect the performance of the slump particularly evident. Mostly bad performance slump concrete transport and waiting time at the site significantly reduced liquidity situation after Pumping performance degradation occurs there. Slump loss has many causes, including environmental factors (temperature, wind, strong sunlight, etc.), high temperature when mixing concrete materials (especially cement), poor water reducing formula, reducing agent and the gelling material suitability bad. Concrete technical personnel should count each brand superplasticizer concrete mixing slump situation provisioning process, as the basis for the re-evaluation of the survival of the fittest, polycarboxylate water reducer synthesis, applying pressure to the water reducer supplier, with a view to improve the ability to adapt and do different superplasticizer cement and water reducer adjustment formula changes with the seasons, thereby reducing the adverse circumstances slump concrete workability or serious damage caused due to poor water reducing formula. In 5-9 months, Sichuan polycarboxylate water reducer, high temperature cement factory, transported to the cement mixing station temperature up to 83 ℃. If the day when the maximum temperature exceeds 30 ℃ or more, mixing concrete above C30 will be excessive slump loss phenomenon; the concrete mixture's temperature reached 32 ~ 34 ℃, when transported to the site reached more than 35 ℃. When using Polycarboxylate If you encounter a machine at higher temperatures (above 32 ℃) will produce the phenomenon of excessive slump loss. The factory slump of 220 ~ 230mm, 150mm and only about half an hour after. In Polycarboxylate incoming inspection time, the time of the loss is zero, 3h after the loss of 50mm. Then take a special test hot water reducer cement performed immediately, through the time it is still very small. After analyzing the reasons for the following conclusions: the test is too small, in the mixing process temperature come down; in production, due to the large square, in the beginning of the mixing process cement hydration, hydration heat generated, so that mixing The temperature of the continued rise, leading to excessive slump loss mix thereof.
