Foreword

GB/T 17431 "Lightweight aggregate and its test method" is divided into two parts. - Part 1. Lightweight aggregate; Part 2. Light aggregate test method. This part is part 1 of GB/T 17431, with EN13055.1..2002 "Lightweight aggregate Part 1. Concrete, mortar and mortar With light aggregate "degree of consistency is not equivalent. This part replaces GB/T 17431.1-1998 "Lightweight aggregate and its test methods Part 1. Lightweight aggregate". This section is the main change compared with GB/T 17431.1-1998 as follows. - revised terms and definitions (Chapter 3 of the.1998 edition, Chapter 3 of this edition); --- revised light coarse aggregate density level ceiling to 1200kg/m3 (1998 version 3.1, 3.1 of this version); - revised the classification of light aggregates (Chapter 4 of the.1998 edition, Chapter 4 of this edition); The sieve was screened into a square sieve and revised to the particle size table (5.1.2, 5.1.2 of this edition); --- increase the nominal grain size 5mm ~ 25mm particle gradation (1998 version 5.1.2, the version of 5.1.2); --- increase the thickness of the mixed light aggregate gradation of the technical indicators (this version of 5.1.3); --- Elimination of homogeneity (1998 version 5.2); --- Elimination of product grade (1998, 4.2, 5.3.1, 5.3.2 and 5.5.1, chapters 4, 5.3.1 and 5.5.1 of this edition); - revised the grain size of the provisions (1998 version 5.5.1, 5.5.1 version); --- Increased the technical requirements for chloride content in lightweight aggregates (5.6 in this edition); - Revised technical requirements for mud content (5.6 in version 5.6 of this edition).
