GB/T 13545-2014Fired hollow bricks and blocks (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB 13545-2003 "sintering hollow bricks and blocks." This standard and GB 13545-2003 "sintering hollow bricks and blocks," compared to the main changes are as follows:

--- The sludge, construction waste and other solid waste materials included in the scope of brick;

--- Canceled superior products, first-class products, qualified quality grade requirements;

2.5 intensity level;

--- Canceled the joint determination of the strength and density;

--- Increasing the requirements and pass the wall of the hole;

--- Cancellation 3h absorption requirements;

--- Increase 5h boiling water absorption requirements;

--- Will receive constant compressive strength fk value of K =

1.8 is adjusted to K = 1.83, in order to promote and improve the uniformity of the strength of the product;

--- Increased due to the brick (block), crisp brick (block) detection;

--- Increase in Appendix B sintered hollow bricks and block schematic diagram. The standard proposed by China Building Materials Federation. This standard by the national wall, roof and road construction materials Standardization Technical Committee (SAC/TC285) with centralized.

1 Scope

GB/T 13545-2014 is the Chinese national standard on fired hollow bricks and blocks, in the field of construction materials and building. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 24 June 2014 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2015. Classification: ICS 91.100.15, CCS Q15. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the sintered hollow bricks and blocks of terms and definitions, product type, size, grading and labeling, technical requirements, test Methods, inspection rules, marking, packaging, transportation and storage. This standard applies to clay, shale, coal gangue, fly ash, sludge (rivers, lakes and other sludges), construction waste and other solid waste As the main raw material, roasting, mainly used for building non-load-bearing parts of hollow bricks and blocks (hereinafter referred to as hollow bricks and Block).
