Detects grouting fullness in bridge prestressed ducts using elastic waves from a magnetostrictive source, with 24-bit high-speed sampling.
Overview
Used to detect grouting compactness and the bond between grout and prestressed tendons in bridges. It uses elastic wave propagation and a giant magnetostrictive elastic wave source: elastic waves are input at one end of the tendon and received at the other end, and the grouting quality is analyzed from the incident and propagated signals. The instrument consists of a magnetostrictive source, geophones, a host and analysis software, and automatically determines grout compactness. It features high sampling accuracy (24-bit A/D, >2MHz), low power consumption (30h battery), large storage (24,000 records), portability (2.0kg), Chinese interface, and Excel export with printout.

FAQ
Q1: What standards does the Prestressed Duct Grouting Quality Detector comply with?
A1: The Prestressed Duct Grouting Quality Detector is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Prestressed Duct Grouting Quality Detector be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
