Introduction
Standard Revision Background and Technological Evolution
GB/T 16753-2023, as the basic terminology standard in the field of silicate building products, has comprehensively upgraded the 1997 version. This revision mainly reflects three major directions of technological evolution: process refinement (12 new process terms such as hydrothermal synthesis reaction were added), product diversification (23 new products such as autoclaved aerated concrete were added), and material environmental protection (9 green raw materials such as recycled aggregates from construction waste were added).
Comparison of terminology system structure
| Chapters | Number of terms in the 1997 version | Number of terms in the 2023 version | Main changes |
|---|---|---|---|
| Raw material terms | 18 items | 32 items | 14 new items such as recycled aggregates from construction waste |
| Product name terms | 24 items | 40 items | Refined classification system for autoclaved products |
| Process terms | 9 items | 16 items | Supplementary new processes such as secondary deep processing |
Analysis of key technical terms
3.1 Silicate building products
The new definition emphasizes the core role of hydrothermal synthesis reaction, and clearly uses hydrated calcium silicate as the main binder, which is different from cement-based products. Typical application case: Autoclaved aerated concrete blocks generate tobermorite crystals through 175℃ saturated steam curing.
7.5 Thickening process
Defines the transition process of slurry from fluid state to plastic state. Key technical indicators include: Ultimate shear stress (≥200Pa), Thickening time (40-60min). This process directly affects the stability of the pore structure of autoclaved aerated concrete board.
Implementation Suggestions
Term Application Scenarios
- Design Documents: Standardized names such as Silicate Hollow Blocks (hollowness ≥ 25%) should be adopted
- Test Report: The void ratio and porosity should be clearly distinguished according to Clause 10.3.6
- Construction Specifications: When citing the definition of machine-made sand in 6.18.7, the powder control requirements should be indicated
Transition Plan between New and Old Standards
| Abolished Terms | Alternative Terms | Technical Basis |
|---|---|---|
| Self-curing fly ash bricks | Steam-cured silicate products | Article 3.8 process classification is more scientific |
| Aerated concrete blocks | Autoclaved aerated concrete blocks | Article 5.23 specifies the maintenance method |
