Abstract

The invention discloses an optimization construction algorithm for aggregate grading of resin concrete. The optimization construction algorithm comprises the following steps that (1) particle diameter intervals are chosen according to an actual aggregate situation; (2) grading orders are chosen according to needs, and particle diameter ranges of the intervals are determined according to the grading orders; (3) according to the selected grading basic parameters, an actual distribution function FF(D) of aggregate grading is established; (4) according to the established actual distribution function and a theoretical distribution function, a target optimization function of the aggregate grading is established; (6) a modern optimization algorithm is adopted to carry out iteration solving on a target, and distribution results of the intervals are obtained. The optimization construction algorithm can be suitable for different aggregate grading orders, grading precision of the aggregate of resin concrete is improved, mechanical performance of produced resin concrete materials is improved, and the manufactured materials can serve as an excellent machine tool structural component.

Description

technical field [0001] The invention relates to the technical field of concrete manufacturing, in particular to a method for constructing high-precision resin concrete multi-level aggregate gradation ratio. Background technique [0002] Ultra-precision machining technology is developing from micrometer and submicrometer to nanometer, which requires processing and measuring equipment with higher precision, static and dynamic performance and thermal stability. The traditional cast iron material can no longer meet the design requirements of the new machine tool structure. The resin concrete material with quartz sand as the aggregate and resin as the binder has the characteristics of high damping, good vibration resistance and strong thermal stability. Precision machine tools have been used to a certain extent. Since most of the components of resin concrete are aggregates, aggregates have an extremely important influence on the performance of resin concrete. [0003] The parti...
