Determination of the strength of reinforcing yarns in cement1 ScopeThis document specifies the principles, test environment, materials and equipment, specimens, operating procedures, results, and other aspects of the determination of the strength of reinforcing yarns in cement. Calculation and test reports. This document is applicable to the evaluation of alkali resistance of reinforcing yarns such as alkali-resistant glass fiber yarn, basalt fiber yarn, and carbon fiber yarn. Evaluation of the alkali corrosion resistance of new reinforcing yarn systems and alkaline corrosion of new cement systems. Other reinforcing yarns are used for reference.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document.

Aging treatment. The alkalinity in cement produces alkaline corrosion on the reinforcing yarn and reduces its strength. The tensile strength is used to evaluate the alkali resistance of the reinforcing yarn or the alkaline corrosion of the reinforcing yarn by the cement system.5 Test environmentThe test should be carried out under laboratory conditions of temperature (23±2)℃ and relative humidity (50±10)%.6 Materials and Equipment6.1 Materials 6.1.1 Cement. P·O 42.5 grade as specified in GB 175-2023. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 45129-2025_English be delivered?Answer: Upon your order, we will start to translate GB/T 45129-2025_English as soon as possible, and keep you informed of the progress.
