Determination of the absorption length of CO2, Nd:YAG and high power diode laser radiation for a selected grouting material [PDF]
, 2002 The laser beam absorption lengths of CO2, Nd:YAG and a high power diode laser (HPDL) radiation for a newly developed SiO2/Al2O3-based tile grout have been determined through the application of Beer-Lambert’s law.

Development of ensemble learning models to evaluate the strength of coal-grout materials
, 2020 In the loose and fractured coal seam with particularly low uniaxial compressive strength (UCS), driving a roadway is extremely difficult as roof falling and wall spalling occur frequently.

A two-stage ceramic tile grout sealing process using a high power diode laser Part II: Mechanical, chemical and physical properties [PDF]
, 1998 Ceramic tiles sealed using a portable 60 W-cw high power diode laser (HPDL) and a specially developed grout material having an impermeable enamel surface glaze have been tested in order to determine the mechanical, chemical and physical characteristics ...

Galvanic corrosion and cathodic protection of re-grouted, post-tensioned (PTd) concrete systems [PDF]
MATEC Web of Conferences, 2023 Grouted post-tensioned (PTd) concrete systems are widely used in long-span segmental bridges with a target service life of 100+ years. However, the usage of inadequate grout materials and grouting practices have resulted in the formation of unwanted air ...

Construction and testing of self-drilled soil nails [PDF]
, 2016 Current standards and best practice guidance recognise that testing of self-drilled hollow bar soil nails can be problematic as conventional packers and debonded lengths cannot be constructed.

Mechanical properties of an improved grout for cementitious precast beam-column joints
Materials Research Express, 2023 This study proposed a new formulation for an improved grout with superior early strength and ultra-high cured strength; it was designed on the basis of the theory of closest packing.
