Gauge Rake – A tool with an adjustable depth gauge designed for application of high-build coatings or cementitious toppings at a preset, uniform thickness.
Glass-Fiber Reinforced Concrete (GFRC) – A portland cement – based composite containing glass fibers for reinforcement. Substantially lower in weight than plain concrete, with higher flexural and compressive strengths. Often used in the production of faux rock formations and concrete countertops.
Granulated Blast Furnace Slag – A glassy, granular material formed when molten blast furnace slag is rapidly chilled. Ground granulated slags are sometimes used in concrete mixtures as a cement replacement to help reduce permeability and improve durability. May also slow setting and extend the working time of the concrete.
Grinding – A mechanical surface preparation method using rotating abrasive stones or discs to remove thin coatings and mastics or slight flaws and protrusions.
Groover – A tool with a V-shaped bit used to create control joints in plasticconcrete.
Grout – A mixture of cementitious materials and water, with or without aggregate, proportioned to produce a creamy consistency. Can be purchased preblended in a multitude of colors to define joints and sawcuts in decorative concrete slabs or walls, especially those with stone, brick, or tile patterns.
