Title:
FRESH CONCRETE WORKING PERFORMANCE CONTROL METHOD BASED ON POURING CONSTRUCTION PERFORMANCE TARGET REGULATION AND CONTROL
Document Type and Number:
WIPO Patent Application WO/2023/065592
Kind Code:
A1
Abstract:
A fresh concrete working performance control method based on pouring construction performance target regulation and control, comprising the following steps: (1) carrying out fresh concrete working performance time-dependent test under various working conditions to obtain concrete working performance time-varying data; (2) establishing a concrete working performance time-varying model based on different working conditions; and (3) determining relevant parameters of the concrete working performance time-varying model according to different working conditions and a working performance control index of a construction node, and calculating the working performance control index of fresh concrete. According to the method, the working performance of the concrete construction node can be controlled, the time evolution rule of the working performance of concrete under different environmental conditions is considered, and the defect that in a traditional method, the working performance of fresh concrete at a stirring and discharging node serves as a control base point, time-varying fluctuation of the working performance is not quantitatively represented and considered, and consequently the concrete state is unstable during construction is overcome.
