Title:
METHOD FOR PREDICTIVE CALCULATION OF SURFACE ENERGY OF AGGREGATE
Document Type and Number:
WIPO Patent Application WO/2023/284113
Kind Code:
A1
Abstract:
Disclosed is a method for predictive calculation of the surface energy of aggregate, steps of said method comprising: (1) screening and grinding original aggregate; (2) obtaining surface texture indices of the ground aggregate and the original aggregate; (3) performing a capillary rise method test on powder aggregate; (4) performing a sessile drop test on the ground aggregate; (5) performing fitting and obtaining a function relational formula; and (6) calculating the surface energy of the original aggregate. During the process of calculating the surface energy of aggregate in the method of the present invention, the influence of a component of the aggregate on the surface energy as well as the influence of grinding smooth said aggregate on a surface texture of the aggregate are both taken into account, actual surface texture conditions of the aggregate are analyzed, sessile drop and capillary rise methods are used in combination to significantly improve test accuracy, same can replace a vapor sorption method in an aggregate surface energy test, and test costs and operational difficulty are greatly reduced.
