Grade is the ground level or elevation of a site. Above grade, on grade or below grade are terms used to categorize construction levels.
Grading is the distribution of particles of granular material and is usually expressed in terms of cumulative percentages larger or smaller than each of a series of sizes. Well-graded aggregate has a large variety of particle sizes and fills a space well while poorly graded aggregate usually has sizes missing.
Gravel mix is a concrete mix which utilizes pea gravel or larger and smoother gravel as its course aggregate. This particular mix is common for exposed aggregate finishes.
Grout is a creamy mixture of cement materials and water utilized to define joints in decorative concrete slabs or walls. Grout is commonly used with stone, brick and tile patterns.
A hard-troweled finish is a concrete finishing process achieved by using a trowel. You can create various effects. Inconsistent troweling is the most common cause of texture while controlling the application will result in a smooth, uniformed finish.
Using a high-pressure water blaster is commonly used on concrete for cleaning or roughening concrete surfaces.
Hydration is the chemical reaction between cement and water. This reaction causes concrete and other cement-based materials to harden.
Inlay is any selected material or object that is integrated into concrete. Shells, broken glass, stones and metal pieces are all common inlays used to provide a higher quality and more unique concrete finish.
Internal curing is when water is supplied throughout a freshly placed cement mixture using reservoirs which release water as needed for hydration or to replace moisture loss through evaporation.
Iron oxide is a pigment often used to color decorative coatings and toppings.
If a concrete slab is connected to something like a wall or column, an isolation joint will isolate the concrete from it. Typically upon the settling of concrete there is restraint which usually causes cracking. An isolation joint allows movement in three different directions to avoid cracking from occurring.
Laitance is a thin layer of loosely bonded particles on the surface of fresh concrete caused by an upward movement of water. Laitance must be removed before a decorative coating is applied.
Light weight aggregate is low-density aggregate used to produce lightweight concrete. Light weight aggregate is used in many forms including expanded clay, slate, natural pumice, tuff or industrial cinders.
