Air Entrained Concrete: Some types of concrete hold billions of microscopic air cells in every cubic foot. These tiny air pockets relieve the internal pressure on the concrete. They provide tiny chambers where water can expand when it freezes. The air is entrained in the concrete by adding various foaming agents such as alcohols, resins, or fatty acids during the mixing process. This must be done under careful engineering supervision since the concrete is mixed on the job site.
Decorative Concrete: Decorative concrete creates visually and aesthetically appealing concrete mixes. Decorative concrete can go through several processes, such as Coloring, Molding, Polishing, Etching, Applying decorative toppings. It is ideal for any project in which you want to make an aesthetic statement. It’s also a great way to add a bit of “personality” to dull surfaces or structures. For instance, swimming pools and flooring can make great use of decorative concrete.
Roller Compacted Concrete: It’s a familiar sight on many American highways — a heavy roller compacting a layer of concrete. Roll-compacted concrete is a strong, dense concrete used on heavily trafficked highways with vehicles that carry large loads. This concrete emits fewer emissions during the production process, which benefits the environment.
Asphalt Concrete: More commonly known as “asphalt” or “blacktop,” this is a form of concrete frequently used on roads, on airport runways, on highways, in parking lots, for sidewalks — basically anywhere pavement is needed. Asphalt is a dark mineral composed of a mixture of hydrocarbons called bitumens.
Ferro Cement Concrete: Highly versatile form of reinforced concrete. It's a type of thin reinforced concrete construction, in which large amount of small diameter wire meshes uniformly throughout the cross section. Mesh may be metal or suitable material. Instead of concrete Portland cement mortar is used.
Fiber Reinforced Concrete (FRC): The steel fiber used in concrete can generally increase the tensile strength by about 2 times, the bending strength by 1.5 ~ 2.5 times, the impact strength by more than 5 times or even 20 times, the ductility by 4 times, and durability by 100 times above.
Fly Ash Concrete: Fly ash use in concrete improves the workability of plastic concrete, and the strength and durability of hardened concrete. Fly ash use is also cost effective. When fly ash is added to concrete, the amount of portland cement may be reduced. Benefits to Fresh Concrete.
Glass Concrete: Another, more modern form of concrete, glass concrete features the use of recycled glass. This form of concrete is used when an aesthetic appeal is an important element in the design of the concrete.
High-density Concrete: High-density concrete or heavyweight concrete is produced using special heavy aggregates (with specific gravities higher than 3000 kg/m3). EN 206:2013+A1:2016 (2016) defines heavyweight concrete as having an oven dry density greater than 2600 kg/m3. The density achieved will depend on the type of aggregate used.
High Strength Concrete: High-performance concrete is a term used to describe concrete with special properties not attributed to normal concrete. High-strength concrete is typically recognized as concrete with a 28-day cylinder compressive strength greater than 6000 psi or 42 Mpa.
Insulating Concrete: Insulating concrete form or insulated concrete form (ICF) is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs.
Light-weight Concrete: Lightweight concrete is a mixture made with lightweight coarse aggregates such as shale, clay, or slate, which give it its characteristic low density. Structural lightweight concrete has an in-place density of 90 to 115 lb/ft³, whereas the density of regular weight concrete ranges from 140 to 150 lb/ft³.
Lime Concrete: Lime mortar today is primarily used in the conservation of buildings originally built using lime mortar, but may be used as an alternative to ordinary portland cement. It is made principally of lime (hydraulic, or non hydraulic), water and an aggregate such as sand.
Normal Strength Concrete: The compressive strength of normal concrete is between 20 and 40 MPa. The strength of high strength concrete is above 40 MPa.
Permeable Concrete: Permeable concrete is a durable concrete pavement with a large volume of interconnected voids. Like conventional concrete, it is made from a mixture of cement, coarse aggregates, and water. However, it contains little or no sand, which results in a porous open-cell structure that allows water to pass through readily.
Pervious Concrete: Pervious concrete has a common strength of 600–1,500 pounds per square inch (4.1–10.3 MPa) though strengths up to 4,000 psi (28 MPa) can be reached. There is no standardized test for compressive strength.
Plain Concrete: Plain concrete, also known as plain cement concrete or PCC, is most commonly used for paving and flooring. Made from a mix of cement, aggregate, and water the different types of aggregate and ratio of materials used will give different types of cement with slightly different properties.
Plum Concrete: It is formed by amalgamating coarse aggregate and cement which are set underneath the foundation or footing of a structure in order to attain a level surface for allocating the load equally. The plum concrete is actually an inexpensive variation of mass concrete.
Polymer Concrete: Polymer concrete is a composite material in which the aggregate is bound together in a matrix with a polymer binder. The composites do not contain a hydrated cement phase, although portland cement can be used as an aggregate or filler.
Prestressed Concrete: Prestressed concrete is a structural material that allows for predetermined, engineering stresses to be placed in members to counteract the stresses that occur when they are subject to loading. It combines the high strength compressive properties of concrete with the high tensile strength of steel.
Precast Concrete: Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and lifted into place ("tilt up"). More recently expanded polystyrene is being used as the cores to precast wall panels.
Pre-Packed Concrete:Prepacked aggregate concrete (PAC) is a type of concrete that is placed in two stages where the coarse aggregates are first placed inside the formworks and then the grout is pumped from underneath through a manual pump.
Rapid Hardening Concrete: Rapid Hardening Portland Cement (RHPC) is a special purpose cement used in concrete to achieve a higher rate of early strength development, compared to using Normal Cement. The improved early performance of RHPC is achieved principally through increased product fineness.
Reinforced Concrete: Reinforced concrete, concrete in which steel is embedded in such a manner that the two materials act together in resisting forces. In reinforced concrete, the tensile strength of steel and the compressive strength of concrete work together to allow the member to sustain these stresses over considerable spans.
Stamped Concrete: Stamped concrete is one of the most popular patio and deck materials worldwide. It is slightly cheaper than pavers and offers a variety of colors and patterns. Since stamped concrete is in fact concrete, it will crack at some point. Installers will try to combat this issue by placing control joints every few feet.
Self-Compacting Concrete: Self-Compacting Concrete (SCC) is defined as concrete that has an ability to flow under its own weight, to fill the required space or formwork completely and to produce a dense and adequately homogenous material without a need for vibrating compaction.
Shotcrete Concrete: Shotcrete, also called (trademark) Gunite, concrete applied by spraying. Shotcrete is a mixture of aggregate and portland cement, conveyed by compressed air to the nozzle of a spray gun, where water is added. The wet mixture is then sprayed in place and may be carved or troweled almost immediately.
Silica Fume Concrete: Silica fume, a by-product of the ferrosilicon industry, is a highly pozzolanic material that is used to enhance mechanical and durability properties of concrete. It may be added directly to concrete as an individual ingredient or in a blend of portland cement and silica fume.
Smart Concrete: Abstract Smart concretes and structures are intelligent systems that have properties different from normal concrete, such as self- sensing and self-healing properties, or have the ability to react upon an external stimulus, such as stress and temperature.
Vacuum Concrete: Vacuum concrete is the one from which water is removed by vacuum pressure after placement of concrete structural member. Vacuum concrete has high strength and durability than normal concrete. Water-cement ratio is detrimental for concrete. These pores result into high permeability and less strength in the concrete.
