Abstract

The invention discloses ultrahigh-strength pump concrete and a preparation method thereof, and relates to the technical field of concrete. The ultrahigh-strength pump concrete comprises cement, ash coal powder, aggregate, artificial sand and a pumping agent. The preparation method comprises the following concrete steps: raw material preparation, aggregate treatment, dust suppression treatment, sound insulation treatment, mixing treatment, blanking treatment, anti-condensation treatment and scraping treatment. Through dust suppression treatment and sound insulation treatment, in an aggregate screening process, an exhaust fan is matched with a dust removal filtering device to suck away dust caused by screening, the dust is purified and treated, and the environment is better protected; noise reduction and sound insulation can be conducted through a sound insulation plate and a sound absorption fence, so an environment is safer; by means of anti-condensation treatment and scraping treatment, in the falling process of concrete, temperature control is conducted on the interior of a stirring machine through cooperation of a temperature measuring device and a heating device, and raw material condensation is prevented; and raw material discharging is assisted and accelerated for the stirring machine through a scraping device and a vibration device, and waste is prevented.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to an ultra-high-strength pumped concrete and a preparation method thereof. Background technique [0002] Pumping concrete is to use concrete pump or pump truck to transport and pour concrete mixture along the delivery pipe. It is an effective way of transporting concrete mixture, with fast speed and less labor force, especially suitable for the transport and pouring of mass concrete and high-rise building concrete. [0003] The existing concrete preparation process usually requires screening, cleaning and mixing of raw materials. However, heavy dust will be generated during the raw material screening process, which will easily cause great harm to the surrounding environment. There will be a lot of noise during the cleaning process, which is likely to cause damage to the ears of nearby workers. At the same time, during the process of concrete preparation and pouring out for storag...
