Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 4111-1997 "Test Method for small concrete hollow block." This standard and GB/T 4111-1997 compared to the main changes are as follows. --- Standard changed its name to "concrete block and brick test methods", expanding the scope of the standard. --- Increased in Chapter 2, normative references and Chapter 3 Terms and definitions. --- Modify the size measurement value method (1997 Edition 2.2.1,2.2.2; 4.2.1,4.2.2 edition). --- To increase and improve the concrete compressive strength test procedure requires the specimen leveling and adhesive material content and requirements (Annex Excerpts Record A); an increase of irregular size and shape of the special concrete block material compressive strength test method (Excerpts Appendix B). --- Modify the bulk density and the hollowness test, test step moisture content, relative water content and water absorption tests (1997 version 5,6; this Chapter 7, 8 edition). --- Carbonation coefficient test method unified carbonation test equipment, environmental conditions and provisions of the test cycle carbonization chamber tank (1997 Version 9.3.2; edition 11.1.2). --- Frost resistance test increases the compressive strength of monolithic block loss rate formula (1997 Version 10.4; 12.5 edition). --- Impermeability tests were revised (1997 Version 11; Chapter 13 edition). The standard proposed by China Building Materials Federation.
