Post-Tensioned Concrete Shear Wall, Purdue Ect Team Aug 2015

Post-Tensioned Concrete Shear Wall, Purdue Ect Team

ECT Fact Sheets

The post-tension concrete shear wall by Tipping Mar will replace the conventional concrete shear wall in earthquake prone areas in many instances, depending on the height and scale of the building.


Rapid Drying Concrete, Purdue Ect Team Aug 2015

Rapid Drying Concrete, Purdue Ect Team

ECT Fact Sheets

One of the essential problems that are faced during construction is the drying of concrete and the presence of moisture which affects floor coverings that need to be placed. The rapid-drying characteristic in Aridusâ concrete allows for the quick reduction of moisture vapor that travels through the concrete pores of the concrete.


Ap Alternatives Modular Solar Racking, Purdue Ect Team Aug 2015

Ap Alternatives Modular Solar Racking, Purdue Ect Team

ECT Fact Sheets

Solar panels have been used to generate and supply electricity in various applications such as residential and commercial buildings. Therefore, a need for a quicker approach to installation as well as the need to reduce workmanship to speed up the process is needed. Solar racks are developed through the use of automated equipment to “preassemble the racking hardware, pre-install the solar modules, and drive helical anchors into the ground rapidly”. So instead of installing one panel at a time, AP Alternatives has created a new method that uses machines to make the process easier. This new automation of the installation …


Prefabricated Building, Purdue Ect Team Aug 2015

Prefabricated Building, Purdue Ect Team

ECT Fact Sheets

With the continuous demand for construction of new buildings, an easier, more sustainable, energy-efficient and environmentally friendly building method is necessary to save time, energy and cost. Hence, there has been an increasing need for a system such as BROAD sustainable building (BSB). A form of prefabricated building by BROAD Sustainable Building Co., LTD (BSB). It consists of flooring and ceiling, embedded shafts of ventilation, water supply & drainage, electricity and lighting. Other items include pillars, diagonal bracings, doors, windows, walls and sanitary wares, air conditioning, air quality products, lifts, building thermal insulations.


Vertical Icf Wall System, Purdue Ect Team Aug 2015

Vertical Icf Wall System, Purdue Ect Team

ECT Fact Sheets

Traditional ICF systems’ installation is tedious and labor intensive resulting in out of level, bowing, and snaking walls with a significant amount of bracing adding to the cost. ICF (Insulated Concrete Form) walls are a form of structural walls used for construction. Hobbs Vertical ICF system uses less concrete, more recycled material and requires less labor for construction. The furring assemblies and retainer clips of the Hobbs VICF system are made from 100% recycled post-industrial waste.


3d Printing For Bricks, Purdue Ect Team Aug 2015

3d Printing For Bricks, Purdue Ect Team

ECT Fact Sheets

Building Bytes, by Brian Peters, is a project that uses desktop 3D printers to print bricks for architecture. Instead of using an expensive custom-made printer, it uses a normal standard 3D printer which is available for everyone and makes it more accessible and also easier for fabrication.


Influence Of Warping On Stress For Restrained Concrete Slabs: For Application To Crcp, Corey M. Beck, W. Jason Weiss, Nathan T. Todd Aug 2015

Influence Of Warping On Stress For Restrained Concrete Slabs: For Application To Crcp, Corey M. Beck, W. Jason Weiss, Nathan T. Todd

The Summer Undergraduate Research Fellowship (SURF) Symposium

Continuously-reinforced concrete pavement (CRCP) is widely used in transportation system because of its low maintenance requirement. However, the need for large volumes of steel creates a high cost for new construction. The Illinois Tollway is preparing to substantially renovate highways in and around Chicago and this work seeks to understand how concretes of varying mixture designs can be made thinner by reducing the amount of built-in stress. The experiment examines warping in beams subjected to various degrees of restraint, in an effort to assess effectiveness at reducing warping in continuously reinforced concrete pavements. Value added methodologies such as internal curing …


Simplified Pavement Design For Lpas: Introduction To Pavexpress, Dudley Bonte Mar 2015

Simplified Pavement Design For Lpas: Introduction To Pavexpress, Dudley Bonte

Purdue Road School

Simplified Pavement Design for LPA's; An introduction to and use of PaveXpress, a simplified, free, web-based pavement design scoping tool for roadway and parking lot pavements. The system was developed by Pavia Systems in partnership with the National Asphalt Pavement Association. PaveXpress creates technical sound pavement structural designs for flexible and rigid pavements based on widely accepted industry standards from the Association of State Highway Officials (AASHTO). The simplified pavement design system is based on empirical equation from the 1993 AASHTO Guide for the Design of Pavement Structures. PaveXpress is intended for use by local agencies, engineers and consultants …
