Concrete pumpability on-site rapid evaluation method based on informatization technology

Abstract

The invention discloses a concrete pumpability on-site rapid evaluation method based on an informatization technology, and belongs to the technical field of pumping concrete application. The problem that an existing concrete pumpability evaluation method is insufficient in accuracy is solved. According to the method, the working parameters of the concrete mixer are monitored by adopting an informatization means; the concrete pumpability on-site rapid evaluation method based on the informatization technology is provided by determining the mapping relation between the working parameters of the mixer truck and the concrete slump expansion degree and the mapping relation between the concrete slump expansion degree and the rheological parameters, and scientific, reliable and rapid evaluation ofthe concrete pumping performance on the construction site is achieved. According to the method, the on-site actual measurement step sequence of the concrete slump expansion index is effectively replaced, the traditional evaluation limitation that the larger the concrete expansion is, the more beneficial the pumping construction is is broken through, concrete segregation is effectively prevented,pipe blocking, pipe explosion and other accidents are reduced, technical support is provided for the pumping construction of concrete, and smooth proceeding of engineering is ensured.

Description

technical field [0001] The invention belongs to the technical field of pumping concrete application, in particular to an on-site rapid evaluation method of concrete pumpability based on information technology. Background technique [0002] Concrete pump slump is a common index to evaluate the performance of concrete pumping. The slump expansion test at the construction site needs to be carried out by a special person. However, during the construction process, some on-site workers are often ineffective due to reasons such as seeking convenience and neglecting their duties. Execution, thus increasing the safety risk of concrete pumping construction. At the same time, with the continuous changes in the composition and performance characteristics of modern concrete mixtures, major changes have taken place in the rheological properties of concrete that have an important impact on pumpability. It can be very large, but its rheological properties and pumping performance are poor. ...

Problems solved by technology

[0004] Aiming at the problem of insufficient accuracy of the current concrete pumpability evaluation method, the purpose of the present invention is to provide a rapid on-site evaluation method of concrete pumpability based on information technology, which uses information technology to monitor the working parameters of concrete mixer trucks, and through the mixer truck The determination of the mapping relationship between working parameters and concrete slump expansion and the mapping relationship between concrete slump expansion and rheological parameters realizes scientific, reliable and rapid evaluation of concrete pumping performance on the construction site, effectively replacing concrete slump The on-site measurement procedure of the slump expansion index breaks through the traditional evaluation limitations of "the greater the concrete slump expansion, the more favorable the pumping construction", effectively prevents concrete segregation, reduces accidents such as pipe plugging and bursting, and provides concrete Provide technical support for pumping construction to ensure the smooth progress of the project
