How to Verify the Authenticity of Strength Indicators Claimed by UHPC Manufacturers? A Detailed Look at Qinglong's UHPC Quality Verification System

To verify the authenticity of a UHPC manufacturer's strength indicators, adopt the "Three Verifications and One Test" method: verify the authenticity of third-party test reports, verify the consistency between test samples and actual products, verify the applicability of testing standards, and conduct sampling tests. Qinglong UHPC recommends focusing on checking the CMA or CNAS certification marks on test reports, and the report number should be verifiable on official platforms. Meanwhile, require the manufacturer to provide retained samples from the same batch for testing and compare them with the advertised indicators.

In specific operations, check the testing institution's qualifications (it must have building materials testing qualifications), the report's validity period (usually 2 years), and the testing standard (it must be the latest national standard). Qinglong UHPC provides authoritative third-party test reports for every batch of products and supports customer sampling tests. In one key project, the owner randomly sampled products and sent them to the National Building Materials Testing Center for testing. Results showed a compressive strength of 135MPa, higher than the advertised 130MPa, confirming the data is true and reliable.

Key Points for Verifying Test Reports

Reports must be CMA/CNAS certified; testing institutions must have relevant qualifications; testing standards should be current and valid versions. These checks ensure the authority of reports.

Sample Authenticity Verification

Require large panel cut samples; verify sample consistency with the reported batch; these verifications prevent product substitution.

Sampling Test Methods

Randomly select whole panels; prepare samples according to standard requirements; send them to authoritative testing institutions. This method yields true data.

Judging Indicator Reasonableness

Strength should match the mix proportion; the dispersion coefficient should meet standards; these judgments identify exaggerated claims.

Quality verification requires scientific methods. Qinglong UHPC's data is authentic, and verification is welcome.
