Abstract

The invention provides a method for designing the ratio of recycled concrete for offshore engineering based on the revised CPM model and rust inhibitor. Firstly, the modified form of the CPM model is proposed to calculate the stacking density of recycled aggregate and cementitious materials mixed in different proportions, and determine Concrete sand ratio and cement-bone ratio; secondly, determine the effective water-cement ratio according to the design strength and the Boromi formula, and use the volume method to obtain the preliminary calculation ratio of concrete; thirdly, determine the amount of rust inhibitor according to the concrete design requirements and service environment; finally , adjust the mix ratio according to the concrete trial mix. The invention combines the stacking model and the rust inhibitor, improves the density of the marine engineering recycled concrete, and delays the process of deblunting and rusting of steel bars.

Description

technical field

[0001] The invention relates to the field of resource utilization of construction solid waste in marine engineering, in particular to a design method for the proportioning design of marine recycled concrete based on a revised CPM model and a rust inhibitor. Background technique

[0002] In recent years, under the background of building a maritime power, the development and utilization of my country's ocean space has entered a new climax, and large-scale coastal or island infrastructure is under construction. As the main building material, concrete has a huge demand, which will accelerate the consumption rate of natural sand and gravel resources. If construction solid waste can be used as raw material and crushed into recycled coarse and fine aggregate for concrete pouring, the shortage of natural sand and gravel resources can be alleviated. Moreover, construction solid waste is easy to collect locally, which is conducive to shortening the construction period...
