Stadium (software)
STADIUM (Software for Transport and Degradation In Unsaturated Materials) is a or service life prediction method which uses finite element software in conjunction with certified lab testing to determine the service life of exposed reinforced concrete. Development SUMMA STADIUM was originally developed in the late 1990s for in-house use by SIMCO Technologies, then an engineering firm specialised in the aging of concrete structures. STADIUM uses time-step finite element analysis to simulate the progress of harmful ions (including chloride, sulphate, and hydroxide) through concrete, by considering the chemical and physical properties of the concrete being analysed. As the US Navy needed a tool to accurately predict the degradation of waterfront concrete structures, SIMCO Technologies and its U.S. partner, the RJLee Group, were awarded Small Business Innovative Research (SBIR) funds from the US Navy for a Phase I feasibility study in 2002. In 2003, Phase II funds were awarded to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finite Element
The finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical modeling. Typical problem areas of interest include the traditional fields of structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential. The FEM is a general numerical method for solving partial differential equations in two or three space variables (i.e., some boundary value problems). To solve a problem, the FEM subdivides a large system into smaller, simpler parts that are called finite elements. This is achieved by a particular space discretization in the space dimensions, which is implemented by the construction of a mesh of the object: the numerical domain for the solution, which has a finite number of points. The finite element method formulation of a boundary value problem finally results in a system of algebraic equations. The method approximates the unknown function over the domain. The simple ...

Simulation Software
Simulation software is based on the process of modeling a real phenomenon with a set of mathematical formulas. It is, essentially, a program that allows the user to observe an operation through simulation without actually performing that operation. Simulation software is used widely to design equipment so that the final product will be as close to design specs as possible without expensive in process modification. Simulation software with real-time response is often used in gaming, but it also has important industrial applications. When the penalty for improper operation is costly, such as airplane pilots, nuclear power plant operators, or chemical plant operators, a mock up of the actual control panel is connected to a real-time simulation of the physical response, giving valuable training experience without fear of a disastrous outcome. Advanced computer programs can simulate power system behavior, weather conditions, electronic circuits, chemical reactions, mechatronics, heat pum ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NJDOT
The New Jersey Department of Transportation (NJDOT) is the agency responsible for transportation issues and policy in New Jersey, including maintaining and operating the state's highway and public road system, planning and developing transportation policy, and assisting with rail, freight, and intermodal transportation issues. It is headed by the Commissioner of Transportation. The present Commissioner is Diane Gutierrez-Scaccetti. History The agency that became NJDOT began as the New Jersey State Highway Department (NJSHD) circa 1920. NJDOT was established in 1966 as the first State transportation agency in the United States. The Transportation Act of 1966 (Chapter 301, Public Laws, 1966) established the NJDOT on December 12, 1966. Since the late 1970s, NJDOT has been phasing out or modifying many list of traffic circles in New Jersey, traffic circles in New Jersey.

Pearl Harbor
Pearl Harbor is an American lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It was often visited by the Naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands are now a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The surprise attack by the Imperial Japanese Navy on December 7, 1941, led the United States to declare war on the Empire of Japan, making the attack on Pearl Harbor the immediate cause of the United States' entry into World War II. History Pearl Harbor was originally an extensive shallow embayment called ''Wai Momi'' (meaning, “Waters of Pearl”) or ''Puuloa'' (meaning, “long hill”) by the Hawaiians. Puuloa was r ...

Holcim
Holcim is a Swiss-based global building materials and aggregates flagship division of the Holcim Group. The original company was merged on 10 July 2015 with Lafarge to form LafargeHolcim as the new company and renamed to Holcim Group in 2021. When the merger was completed, the Holcim brand was retained within the group. Founded in 1912, the company expanded into France and then throughout Europe and Middle East during the 1920s. They expanded in the Americas during the 1950s and went public in 1958. The company continued to expand in Latin America and added Asian divisions during the 1970s and 1980s. A series of mergers and buyouts made Holcim one of the two largest cement manufacturers worldwide by 2014, roughly tied with rival Lafarge. In April 2014, the two companies agreed to a US$60 billion "merger of equals". The company was the market leader in cement production in Australia, Azerbaijan, India, Slovakia, Switzerland, and Latin America. Overview Holcim is headquarter ...

Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lafarge (company)
Lafarge is a French industrial company specialising in cement, construction aggregates, and concrete. It is the world's largest cement manufacturer. It was founded in 1833 by Joseph-Auguste Pavin de Lafarge and is a part of the Holcim Group. In 2015, Lafarge merged with Holcim and a new company was formed under the name of LafargeHolcim. It was renamed to Holcim Group in 2021.
