Strict control of vibration and the vibration time since the radius superplasticizer concrete admixture prepared slump generally larger, the lower the viscosity of plus mixing, so vibrated radius after pouring concrete mixture and the vibration time should be determined by tests, or should follow the guidance of experts. Vibration radius is too small, or vibrated too long, very easily lead to a serious decline in gas content in the concrete, aggregates phase and slurry-phase stratified serious structural defects. Commodity concrete water reducer used in Bijie Prefecture polycarboxylate water reducer, improve the workability of concrete, but also become factors concrete workability fluctuations, Polycarboxylate yield, in which the slump properties effect is 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, to exert pressure on suppliers of water reducer, powder polycarboxylate water reducer, 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.
