Providing Advanced Testing + Forensic Capabilities For Construction Materials

Thorough testing and analysis on construction materials is sometimes needed before, during and after construction to ensure a structure’s integrity and safety. Our accredited and independent Materials Laboratory houses state-of-the-art equipment for standardized and specialty testing and applied research. The laboratory provides chemical and physical testing and petrography for aggregates, 水泥, 砂浆, concrete and other construction materials.

岩相学的服务

Petrographic methods combine visual analyses using stereo, petrographic and scanning electron microscopes to examine and evaluate the optical properties and microstructural characteristics of the materials


The information from a petrographic analysis is regularly used to identify causes of distress and deterioration in materials, as well as predict future performance of the materials, and can aid in the evaluation of several issues, 其中包括, 但不限于:

  • 表面扩展
  • 分层
  • Improper Finishing or Curing Techniques
  • 染色变色
  • 破裂的原因
  • 冻融恶化
  • 钢筋腐蚀
  • 总可以
  • 长强度结果
  • 灰骨反应
  • 化学攻击
  • 混合设计验证
  • 涂层的失败
  • 与火和热有关的损害
