Recycling of waste concrete is one of the sustainable solutions for the growing waste disposal crisis and depletion of natural aggregate sources. As a result, recycled concrete aggregate (RCA) is produced, and so far it has mostly been used in low-value applications such as for the pavement base. But, from the standpoint of promoting resource and energy savings and environmental …

RECYCLING AND DEMOLITION. Southern Crushed Concrete (SCC) is a Texas-owned company established in 1991. With the use of practical and inexpensive methods, SCC is able to produce recycled concrete for a variety of construction projects throughout Southeast Texas. More Info.

Concrete Waste Containers are made from durable fiberglass-reinforced polymer concrete for long lasting durability and easy maintenance. 30 Gallon Square Containers include an easy-lift funnel shaped lid for easy trash removal and elastic band bag attachment that secures bags in place.

Fiber-reinforced concrete is ideal for improving the durability and toughness performance of concrete and mortar. Fibers in concrete help reduce shrinkage cracks, increase strength, increase energy absorption and reduces dangerous spalling at high temperatures. Sika is the leading company for fiber-reinforced concrete solutions.

Textile-reinforced concrete (TRC) is a composite construction material consisting of high-performance textiles made of glass or carbon fibre filament yarns embedded in a matrix of fine-grained concrete [].TRC offers many advantages compared to conventional reinforced concrete such as non-corrosiveness [], high tensile strength, light and thin-walled design [].

Jointed reinforced concrete pavement (JRCP, see Figure 1) uses contraction joints and reinforcing steel to control cracking. Transverse joint spacing is longer than that for JPCP and typically ranges from about 7.6 m (25 ft.) to 15.2 m (50 ft.).

This paper is related to a laboratory program for the shear strength of reinforced concrete corbels (RCC) cast with or without recycled aggregate (RA) by investigating the main parameters affecting the corbels behavior including the replacement aggregate recycling ratio, fcu, and shear span to effective depth ratio a/d. Eight specimens were cast and tested.

Recycling and reuse. Scarcity of resources and the need to reduce the environmental impacts of winning and processing construction materials and products is placing a greater emphasis on resource efficiency within the construction industry. It is estimated that the UK construction industry consumes some 400Mt of materials annually and generates ...

For decades, recycled coarse aggregate (RCA) has been used to make recycled aggregate concrete (RAC). Numerous studies have compared the mechanical properties and durability of recycled aggregate concrete (RAC) to those of natural aggregate concrete (NAC). However, test results on the shear strength of reinforced recycled aggregate concrete beams are still limited and sometimes contradictory.

Reinforced concrete. The embodied energy of producing concrete is about 380 kg of CO2 per m³ concrete in structural components such as floors and columns. It is about 310 kg of CO 2 per m³ concrete in pad foundations or the like. Increasingly, though, cement may be partly replaced by alternatives such as pulverised fuel ash (PFA), a by ...

Schaefer and Ortega began to explore the possibility of plastic-reinforced concrete as part of 22.033 (Nuclear Systems Design Project), in which students were asked to pick their own project. "They wanted to find ways to lower carbon dioxide emissions that weren't just, 'let's build nuclear reactors,'" Short says.

Thanks to developments in concrete recycling equipment, any type of concrete can be recycled, whether it be plain, mesh-and-dowel or continuously-reinforced concrete. The process can remove steel to reduce hand labour. There is breaking equipment for all pavement types and crushing equipment that handles steel reinforcement.

Successful and economical recycling projects have included jointed plain pavement, jointed reinforced pavement, continuously reinforced pavement and even airport pavement over 17 inches thick. Arrangements can be made to haul concrete from a demolition site to the recycling plant, or, in some cases, recyclers are able to move portable recycling ...

A range of fibre reinforced ready-mix concretes including Polypropylene Fibres, Advanced Polypropylene Fibre, and Steel Fibres. Enhanced crack control. Increased load capacity & ductility. Improved durability. Surface abrasion resistance. Long lasting concrete. & More. See more about Fibre Concrete.

Recycling of polyvinyl chloride (PVC) cables and wires from electronic waste (e-waste) to produce a new product such as fibre-reinforced concrete (FRC) is one of the best solutions for disposing of PVC cables, and it could reduce the hazardous burden on the environment.

Mechanical properties of recycled concrete aggregate (RCA) and recycled asphalt pavement (RAP) were evaluated for use as backfill in mechanically stabilized earth (MSE) walls. Large scale triaxial compression tests, interface direct shear tests, and pull-out tests were conducted to evaluate interaction of RCA and RAP with geosynthetics.

Plastics have become an essential part of our modern lifestyle, and the global plastic production has increased immensely during the past 50years. This has contributed greatly to the production of plastic-related waste. Reuse of waste and recycled plastic materials in concrete mix as an environmenta …

Reinforced concrete is a composite material, and the average density is considered to be 150 lb/ft3. It has the properties that it will creep (deformation with long term load) and shrink (a result of hydration) that must be considered. Construction

Recycling concrete consists of breaking, removing, and crushing concrete from an existing location, and then using it to create a new, reusable material. There are many benefits and uses of recycled concrete, and it's often the best option for concrete removal.

Fiber-reinforced concrete (FRC) is concrete made primarily of hydraulic cements, aggregates, and discrete reinforcing fibers. Fibers suitable for reinforcing concrete have been produced from steel, glass, and organic polymers (synthetic fibers). Naturally occurring asbestos fibers and vegetable fibers, such as sisal and jute, are also used for reinforcement.

Recycled concrete aggregate (RCA) collected from the demolition of old reinforced concrete structures can be reused to prepare structural and non-structural concrete, thereby protecting the environment by preserving natural resources. This study explores RCA's use, collected from the crushed concrete of different building projects in Riyadh, to manufacture fresh self-compacting concrete (SCC ...

2. Economical . Concrete constituents are widely available worldwide and inexpensive. Similarly, the production cost of concrete is very low. There is an overall economy by using reinforced concrete because its maintenance cost is low due to the long-lasting nature of reinforced concrete.
