Entirely grouted cable tendons are commonly used in mining engineering. They have superior working ability reinforcing the excavated rocks and soils. During process of tendons, force-transferring corresponding mechanism significant guaranteeing safety underground openings. To further understand entirely this paper provided a literature review on force transfer tendons. First, concept was summar...

This paper discusses field tests developed by the Getty Conservation Institute to evaluate injection grouts for comparison and quality control of materials and mixtures. Field test methods discussed include injection with syringe, flow with syringe, expansion and bleeding, wet density, drying shrinkage, and final setting time. Four commercial grouts and an ICCROM grout with four modified versio...

The worldwide use of precast concrete frames leads to an increase in the need for the investigation of efficient precast connections, particularly in the seismic regions. The current paper provides a numerical and experimental study on a dry precast connection. Experiments were conducted to validate the finite element method in the laboratory of the University of Science and Culture. To verify ...

This paper describes an approach for predicting the diameter of a jet-grout column using support vector regression (SVR) technique, which is regarded as novel learning machine based upon recent advances in statistical theory, combined effects construction (construction methods and jetting parameters) soil properties (soil type shearing resistance) are considered. Four different kernel functions...

Abstract Reinforced concrete bridges with post‐tensioned cables are particularly critical structures, as the degradation of tendons is not fully detectable through conventional investigation methods and/or visual inspections, due to intrinsic nature structural typology. After shortly reviewing main applications current non‐destructive (ND) available for investigating deterioration and grout, pa...
