Usually the concrete is stained first to provide it color, so the routed areas look like grout lines. Efflorescence - A crystalline deposit of salts (typically 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 environment. (Likewise see surface area retarder.) Feather edge - To efficiently, effortlessly 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 utilized alone or in combination with rebar or bonded wire mesh to reinforce concrete.
Film-forming sealer - A kind of sealant that obstructs the penetration of water and contaminants by forming a barrier on the concrete surface. May likewise impart a gloss or sheen, which improves colored or exposed aggregate concrete. See likewise membrane. Flashing (or flash broadcasting) -A strategy for applying accent colors of dry-shake hardenerto concrete surfaces prior to stamping.
Flexural strength - The capability of hardened concrete or an overlay to withstand failure in bending. Drift surface - Surface area texture (usually rough) obtained by ending up with a bull float or hand float. Flooring polisher - A walk-behind device used in the production of sleek concrete. The majority of machines are geared up with a planetary drive system, a large primary polishing head (from 17 to 36 inches in diameter) fitted with 3 or four smaller sized satellite heads that hold the diamond abrasives.
An Excellent Lesson about Concrete Construction( Also see diamond grinding, dry polishing, damp polishing). Fly ash - A supplemental cementitious product (SCM) Fly ash is a by-product arising from the combustion of ground or powdered coal; in some cases utilized as a cement replacement in concrete. Form liner - Product used to line the interior face of formwork in order to impart a smooth or patterned architectural finish.
Long handles (like those used for bull floats) either clip on or screw into the blade. NOTE: Fresnos ought to never ever be used on air-entrained outside concrete as it seals over the top of the piece trapping bleed water below the surface area. Finishing - The treatment (compacting, leveling, smoothing, and so on) of just recently positioned or fresh concrete to make sure the planned-for surface area.
Assess rake - A tool with an adjustable depth gauge designed for application of high-build finishings or cementitious garnishes at a preset, uniform density. Gravel Mix - A concrete mix that uses either pea gravel or larger smooth gravel as its coarse aggregate. This mix is normal for exposed aggregate finishes.
Some News abour Concrete Construction
Likewise used in classifying building or building levels, e.g. above grade, on grade, or below grade. Granulated blast heater slag-- A supplementary cementitious product (SCM) formed when molten blast heater slag is rapidly chilled. Ground granulated slags are in some cases utilized in concrete mixes as a cement replacement to assist minimize permeability and enhance resilience.
Alleviates the capacity for Alkali-Silica Response. Grinding - A mechanical surface preparation technique utilizing turning abrasive stones or discs to eliminate thin coatings and mastics or slight defects and protrusions. Grout - A mixture of cementitious materials and water, with or without aggregate, proportioned to produce a velvety consistency. Can be purchased preblended in a plethora of colors to define joints and sawcuts in decorative concrete pieces or walls, specifically those with stone, brick, or tile patterns Groover - A tool with a V-shaped bit used to create control joints in plastic concrete.
Particularly helpful for drifting along the boundary of forms or to work in difficult situations. Hard-troweled surface - Surface surface obtained by utilizing a trowel with a steel blade for last finishing of concrete. Frequently used where a smooth, hard, flat surface is desired. High-pressure water blasting - A process for cleaning or roughing up concrete surfaces utilizing a stream of water delivered at high pressure.
Additional Concrete Construction Things To KnowHopper gun - A gravity-fed system for spray application of coverings or toppings. The product is positioned in a hopper attached to a spray gun, which is powered by an air compressor. Typically utilized to use spray-down systems. Hover Trowel - A trademarked lightweight power trowel developed specifically for accuracy ending up of epoxy, polymer customized, and cementitious overlay systems.
Essential color - A coloring agent premixed into fresh concrete or cementitious garnishes before placement. Iron oxide - An inorganic pigment often utilized to color ornamental finishings and garnishes. Seclusion Joint - Seclusion (or growth) joints separate or isolate slabs from other parts of the structure such as walls, footings, or columns; and driveways and outdoor patios from pathways, garage slabs, stairs, light-poles and other points of restraint.
Joint (control, expansion, or seclusion) - Formed, sawed, or tooled groove in a concrete slab utilized to control the place of cracking (control joint) or to permit growth or movement of adjacent structures. In ornamental concrete, joints can likewise double as defining design components in a pattern. See: filler - A compressible material utilized to fill a joint to prevent the infiltration of particles.
Concrete Construction The Right WayKCMMB Mix - A concrete mix specification designed by the Kansas City City Materials Board for longer long lasting concrete by creating a mix design requirement of specific materials and difficult rock aggregates that can reduce the effects of salts, deicers, and alkali-silica-reactivity. Kneeboards - Boards used by concrete finishers to kneel on when hand drifting 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 must be gotten rid of prior to application of a decorative finish or topping. Marbleize - To give concrete surface areas the look and gloss of marble, through a combination of color layering and ending up methods.
It has several uses, including scraping off concrete from finishing tools and applying patching materials. Masking - Covering choose areas of a concrete surface area with an adhesive stencil, tape, or other medium before using an ornamental treatment that will affect only the exposed areas. Material security information sheet (MSDS) - Details sheets including relevant chemical components, item handling and safety standards.
The A - Z Guide Of Concrete Construction
Typically clear plastic like acrylic, polyurethane or epoxy. Microtopping - An ultra-thin polymer-based ornamental topping, usually less than 1/4-inch total density. Usually applied by trowel or squeegee, and offered a texture or smooth finish. Pigments can be integrated into the mix or broadcast onto the surface area for a marbleized appearance.
Commonly used to signify covering thickness. Mix design - Specific percentages of ingredients (cement, aggregates, water, and admixtures) used to produce concrete matched for a specific set of task conditions. Mockup - An architectural concrete sample used the exact same products and approaches proposed for a real job. Often required for quality assurance on big tasks, to ensure that architectural requirements and market tolerances are fulfilled.
