Technical data
“Requirement” is the stated acceptance threshold or range. “Actual result”, “typical value” and “published value” are not guaranteed minima unless the requirement column says so. Final acceptance must follow the approved TDS, report, test method and project conditions.

| Compressive strength - 3 days | ≥80 MPa | Actual result89.4 MPa | Independent commissioned test |
| Compressive strength - 28 days | ≥140 MPa | Actual result150.3 MPa | Independent commissioned test |
| Initial flowability | ≥290 mm | Actual result302 mm | Independent commissioned test |
| 30-minute flowability | ≥260 mm | Actual result271 mm | Independent commissioned test |
| 3-hour vertical expansion | ≥0.02% | Actual result0.05% | Independent commissioned test |

English technical data sheet
Prepared from the supplied Sino-sina Building Materials Co., Ltd. product manual. Requirements are kept separate from published or reported values. Use the current controlled document and project specification for final approval.
Independent test evidence
Values in the reported-result column were transcribed from independent laboratory reports supplied by Sino-sina. Public material retains Sino-sina Building Materials Co., Ltd. and, where positively verified, the testing institution and report reference; project/client identities, personnel, signatures, stamps, QR codes and contact addresses are omitted.
Photographed field method
These upright site photographs document controlled mixing, secondary grouting around the anchor system and the completed load-transfer zone. They support the method statement; they do not replace the approved product TDS or project inspection plan.
