Typically the concrete is stained initially to offer it color, so the routed locations look like grout lines. Efflorescence - A crystalline deposit of salts (normally white in color) that forms on the concrete surface area when soluble calcium hydroxides leach from the concrete and combine with carbon dioxide in the atmosphere. (Also see surface area retarder.) Feather edge - To smoothly, perfectly blend the edge of a topping or repair material into the existing concrete. Fibers - Tiny filaments made from polypropylene, polyolefin, nylon, polyethylene, polyester, or acrylic used alone or in combination with rebar or bonded wire mesh to strengthen concrete.
Film-forming sealant - A type of sealer that blocks the penetration of water and pollutants by forming a barrier on the concrete surface. Might also impart a gloss or sheen, which improves colored or exposed aggregate concrete. See also membrane. Flashing (or flash broadcasting) -A method for using accent colors of dry-shake hardenerto concrete surface areas prior to stamping.
Flexural strength - The capability of solidified concrete or an overlay to resist failure in bending. Float surface - Surface area texture (normally rough) acquired by ending up with a bull float or hand float. Flooring polisher - A walk-behind machine utilized in the production of polished concrete. Many machines are equipped with a planetary drive system, a large primary polishing head (from 17 to 36 inches in size) fitted with 3 or 4 smaller sized satellite heads that hold the diamond abrasives.
Advanced Concrete Construction( Also see diamond grinding, dry polishing, wet polishing). Fly ash - A supplemental cementitious product (SCM) Fly ash is a by-product resulting from the combustion of ground or powdered coal; in some cases used as a cement replacement in concrete. Kind liner - Product utilized to line the interior face of formwork in order to impart a smooth or patterned architectural finish.
Long deals with (like those used for bull floats) either clip on or screw into the blade. NOTE: Fresnos must never be utilized on air-entrained outside concrete as it seals over the top of the slab trapping bleed water listed below the surface. Ending up - The treatment (condensing, leveling, smoothing, and so on) of recently positioned or fresh concrete to guarantee the planned-for surface.
Assess rake - A tool with an adjustable depth gauge designed for application of high-build finishes or cementitious toppings at a preset, uniform thickness. Gravel Mix - A concrete mix that makes use of either pea gravel or larger smooth gravel as its coarse aggregate. This mix is normal for exposed aggregate surfaces.
What Does Concrete Construction Really Mean?
Likewise used in classifying structure or construction levels, e.g. above grade, on grade, or listed below grade. Granulated blast furnace slag-- An extra cementitious material (SCM) formed when molten blast furnace slag is rapidly cooled. Ground granulated slags are in some cases utilized in concrete mixtures as a cement replacement to help in reducing permeability and enhance toughness.
Alleviates the potential for Alkali-Silica Response. Grinding - A mechanical surface area preparation approach using rotating abrasive stones or discs to remove thin finishings and mastics or minor defects and protrusions. Grout - A mix of cementitious materials and water, with or without aggregate, proportioned to produce a velvety consistency. Can be bought preblended in a multitude of colors to specify joints and sawcuts in ornamental concrete pieces or walls, especially those with stone, brick, or tile patterns Groover - A tool with a V-shaped bit utilized to create control joints in plastic concrete.
Especially helpful for drifting along the border of forms or to operate in tight areas. Hard-troweled surface - Surface area surface acquired by utilizing a trowel with a steel blade for final ending up of concrete. Typically used where a smooth, hard, flat surface area is preferred. High-pressure water blasting - A process for cleansing or roughing up concrete surface areas using a stream of water provided at high pressure.
Main Benefits of Concrete ConstructionHopper gun - A gravity-fed system for spray application of finishes or garnishes. The product is put in a hopper connected to a spray gun, which is powered by an air compressor. Typically utilized to apply spray-down systems. Hover Trowel - A trademarked lightweight power trowel established particularly for accuracy completing of epoxy, polymer modified, and cementitious overlay systems.
Integral color - A coloring agent premixed into fresh concrete or cementitious toppings prior to placement. Iron oxide - An inorganic pigment frequently utilized to color decorative finishings and toppings. Seclusion Joint - Isolation (or growth) joints different or isolate pieces from other parts of the structure such as walls, footings, or columns; and driveways and patio areas from sidewalks, garage slabs, stairs, light-poles and other points of restraint.
Joint (control, expansion, or isolation) - Formed, sawed, or tooled groove in a concrete piece used to manage the area of breaking (control joint) or to permit expansion or movement of adjacent structures. In decorative concrete, joints can also double as marking design aspects in a pattern. See: filler - A compressible material used to fill a joint to avoid the seepage of particles.
An Excellent Lesson about Concrete ConstructionKCMMB Mix - A concrete mix specification created by the Kansas City City Materials Board for longer lasting concrete by producing a mix style requirement of particular products and tough rock aggregates that can mitigate the results of salts, deicers, and alkali-silica-reactivity. Kneeboards - Boards utilized by concrete finishers to kneel on when hand floating or troweling concrete flatwork.
Laitance - A thin layer of fine, loosely bonded particles on the surface of fresh concrete, triggered by the upward motion of water. Laitance needs to be eliminated prior to application of an ornamental finish or topping. Marbleize - To give concrete surfaces the appearance and gloss of marble, through a mix of color layering and completing methods.
It has numerous usages, consisting of removing concrete from finishing tools and applying patching products. Masking - Covering select locations of a concrete surface area with an adhesive stencil, tape, or other medium before applying an ornamental treatment that will affect just the exposed locations. Material security data sheet (MSDS) - Information sheets consisting of essential chemical active ingredients, product handling and security standards.
Main Benefits of Concrete Construction
Generally clear plastic like acrylic, polyurethane or epoxy. Microtopping - An ultra-thin polymer-based decorative topping, usually less than 1/4-inch overall density. Usually used by trowel or squeegee, and offered a texture or smooth finish. Pigments can be included into the mix or broadcast onto the surface area for a marbleized appearance.
Typically utilized to denote covering thickness. Mix design - Specific percentages of components (cement, aggregates, water, and admixtures) used to produce concrete matched for a particular set of task conditions. Mockup - An architectural concrete sample made using the same products and techniques proposed for an actual job. Typically needed for quality control on large projects, to guarantee that architectural requirements and industry tolerances are met.
