Its use in various types of buildings is growing throughout the nation. Architects are specifying precast concrete for the design flexibility it gives them both in space planning and the variety of architectural features available. Engineers are attracted to longer spans, shallower depths and inherent fire resistance.

General Contractors like precast for its speed of construction and limited impact to the job site. Owners are attracted to the more durable, low maintenance buildings that precast concrete provides.

Precast components are manufactured in advance, stored, and are readily available when needed at the job site. This capability can be used to provide custom made design solutions to specific problems and also aesthetically pleasing finishes.

This is extremely important when calculating life-cycle costs for a project. Concrete is naturally and inherently fire resistant and needs no additional application of fire protection.

This is extremely beneficial for above-ground applications. Precast concrete products can be designed to withstand anticipated corrosive agents. Precast concrete products produced in a quality-controlled environment offer superior watertightness. In addition, weather conditions at the jobsite do not significantly affect the schedule.

Precast products are designed and manufactured for simple connections and fast installation. This is becoming an increasingly important issue. A simple concept, Reduce, Reuse, Recycle Sustainability means living and working in a manner that does the least harm to the earth. A good description is infinitely beneficial. The most acceptable definition emerged in in the U.

World Commission on Environment and Development Brundtland Report Our Common Future sustainable development is that development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Because precast concrete is factory-made, there is little waste created in the plant and it reduces construction waste and debris on site, reducing construction IAQ concerns.

The thermal mass of concrete allows shifting of heating and cooling loads in a structure to help reduce mechanical system requirements.Precast concrete is an industrialized way to build. It means transfer of work from sites to factories. This improves productivity and quality and shortens construction time of a building. In short, precast concrete lowers total construction costs considerably. Precast also has lower lifetime costs than any other building solution.

It is possible due to consistent high quality of industrially produced products. Precast minimizes e. With precast, logistics needs are minimal. Precast floors, walls, frames and foundations are transported to a construction site ready-to-install. Logistics to building site is arranged with just one delivery vehicle instead of several raw material transfers back and forth.

Precast concrete suits well for any type of building: residential, commercial, industrial, public to name a few.

There is a suitable solution for both indoor and outdoor precast production. The smart match can be found for different kinds of building projects in terms of elements produced, factory capacity and labor needs. Precast can be made into any shape or color and finished with several techniques. This together with longer spans gives architects and other designers more freedom than ever.

Precast can be used as the only building material, but it can as well be combined with steel or be utilized as a composite structure only. Use of precast in a building depends largely on local building traditions and restrictions. Take a look at examples of precast buildings. It produces less waste on the site and in the factory. This makes CO2 footprint of precast much smaller than in cast-in-situ construction.

Precast offers a safer and healthier working environment. Material handling is easier and less scaffolding is needed. Precast technology works in virtually all environments — cold, hot, moist or dry. To avoid too fast or slow hardening in more hot, moist or dry climates, several curing and concrete mixing solutions can be applied.

As an industrially produced building material, precast is always of the highest quality. In production of precast, selected raw materials are used following carefully designed production process.

The controlled environment enables real time monitoring and easy adjustments. The outcome is totally cured, finished and equipped. High quality precast does not breed any harmful microbes, either. Elematic offers all precast production technologies needed for any type of building construction.

Explore precast references worldwide. You can find production lines as well as buildings.Precast concrete is a construction product produced by casting concrete in a reusable mould or "form" which is then cured in a controlled environment, transported to the construction site and lifted into place.

In contrast, standard concrete is poured into site-specific forms and cured on site.

Behind The Scenes Of A Precast Concrete Plant - Oldcastle Precast

By producing precast concrete in a controlled environment typically referred to as a precast plantthe precast concrete is afforded the opportunity to properly cure and be closely monitored by plant employees. The production process for Precast Concrete is performed on ground level, which helps with safety throughout a project.

There is a greater control of the quality of materials and workmanship in a precast plant rather than on a construction site. Financially, the forms used in a precast plant may be reused hundreds to thousands of times before they have to be replaced, which allows cost of formwork per unit to be lower than for site-cast production. Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies or sub-assemblies to the construction site where the structure is to be located.

The term is used to distinguish this process from the more conventional construction practice of transporting the basic materials to the construction site where all assembly is carried out. Pre stressed slab-column system Another type of precast system is a slab-column system that uses horizontal pre stressing in two orthogonal directions to achieve continuity.

The precast concrete column elements are 1 to 3 stories high. The reinforced concrete floor slabs fit the clear span between columns. After erecting the slabs and columns of a story, the columns and floor slabs are pre stressed by means of pre stressing tendons that pass through ducts in the columns at the floor level and along the gaps left between adjacent slabs. Site-cast local precast : -no transportation -the size limitation is depending on the elevation capacity only -lower quality because directly affected by weather -proper, large free space required.

Precast at a plant: -transportation and elevation capacity limits the size -higher, industrialized quality less affected by weather. Learn more about Scribd Membership Home. Read Free For 30 Days.

Date uploaded Dec 14, ARCH V These components are manufactured by industrial methods based on mass production in order to build a large number of buildings in a short time at low cost. The main features of this construction process are as follows The division and specialization of the human workforce. The use of tools, machinery, and other equipment, usually automated, in the production of standard, interchangeable parts and products.

This type of construction requires a restructuring of the entire conventional construction process to enable interaction between the design phase and production planning in order to improve and speed up the construction. One of the key premises for achieving that objective is to design buildings with a regular configuration in plan and elevation. This all combined can affect the cost a lot.

Theoretically, all joints between the precast units could be made in such a way that the completed precast structure has the same monolithic concept as a in-situ one. If the full advantages of precast concrete are to be realized, the structure should be conceived according to its specific design requisites.

Depending on the load-bearing structure, precast systems can be divided into the following categories: Large-panel systems Frame systems Slab-column systems with walls Mixed systems. Pictures indicating buildings which have used precast panels and pre cast blocks as building materials.

These were used as the time factor was to be given maximum importance. Very large sized members can not be cast monolithically, it creates problems in transporting them and are very heavy. The designation large-panel system refers to multistory structures composed of large wall and floor concrete panels connected in the vertical and horizontal directions so that the wall panels enclose appropriate spaces for the rooms within a building.

These panels form a box-like structure. Both vertical and horizontal panels resist gravity load. Wall panels are usually one story high. Horizontal floor and roof panels span either as one-way or two-way slabs.

When properly joined together, these horizontal elements act as diaphragms that transfer the lateral loads to the walls. Depending on the wall layout, there are three basic configurations of large-panel buildings: Cross-wall system. The main walls that resist gravity and lateral loads are placed in the short direction of the building.

Longitudinal-wall system. The walls resisting gravity and lateral loads are placed in the longitudinal direction. Two-way system. The walls are placed in both directions. Panel connections represent the key structural components in these systems.Toggle navigation. Help Preferences Sign up Log in. Featured Presentations.
