The previous versions of this document and its superseded documents are as follows. This document was first published in.2008 and this is the first revision.IntroductionRefractory mud is generally used as the joint material of refractory masonry, so that the masonry forms a tight whole to resist the damage of external force and prevent gas, Intrusion of molten liquid. Masonry joints are usually the weak link of the masonry, and in most cases are damaged before the masonry, so the quality of the refractory mortar is It is closely related to the overall life of the masonry. The particle size of refractory mud is an important indicator to characterize its particle gradation, which directly affects the quality performance and construction performance of refractory mud, and ultimately affects the quality of refractory mud. The service life and safety of refractory masonry are affected. The first 6 parts of GB/T 22459 are modified to adopt ISO 13765, GB/T 22459 Parts 7 and 8 have no correspondence with ISO 13765. GB/T 22459 "Refractory Mud" consists of 8 parts. --- Part 1.Consistency test method (cone penetration method), the purpose is to determine the consistency of refractory mud; --- Part 2.Consistency test method (jumping table method), the purpose is to determine the consistency of refractory mud; --- Part 3.Test method for bonding time, the purpose is to determine the time required for the stability of the bonding of refractory mortar joints when building refractory masonry take time; --- Part 4.Test method for flexural bonding strength at room temperature, the purpose is to determine the resistance of refractory mortar joints after refractory masonry is built. folded bond strength; --- Part 5.Test method for particle size distribution (sieve analysis), the purpose of which is to determine the particle size distribution of refractory mud; --- Part 6.Test method for water content of pre-mixed mud, the purpose of which is to determine the moisture content of pre-mixed mud; --- Part 7.Other performance test methods, the purpose is to determine the refractoriness of refractory mud, high temperature flexural bonding strength, room temperature flexural strength degree, thermal expansion, thermal conductivity, etc.; --- Part 8.Bleeding test method, the purpose is to determine the bleeding performance of refractory mud at rest or under a certain load. This document is part 5, and the other 7 parts belong to the test method for refractory mud, which together constitute the test method for refractory mud system. refractory mud Part 5.Test method for particle size distribution (sieve analysis)1 ScopeThis document specifies the principles, equipment, sampling, test procedures, results calculation and experiment report.
