GB/T 1346-2024 Test methods for water requirement of standard consistency, setting time and soundness of the portland cement 1 Scope This document specifies the principle, apparatus, test water, test conditions and determination methods of water requirement of standard consistency, setting time and test methods for volume soundness mainly caused by free calcium oxide. This document is applicable to the test for water requirement of standard consistency, setting time and soundness of general portland cement. 2 Normative references The following documents contain requirements which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Metal test bar (test bar method) or test cone (test cone method) is used to sink cement paste with different moisture contents. When the test bar or test cone can stay at the specified balance position, the moisture content is the water requirement of standard consistency, and the paste is cement paste of standard consistency. 4.2 Soundness after boiling 4.2.1 Le Chatelier test
