Materials engineers are responsible for the research, specification, design and development of materials to advance technologies of many kinds. Their expertise lies in understanding the properties and behaviours of different substances, from raw materials to finished products. The field is also referred to as materials science or materials technology. They work with many different materials, including: ceramics; chemicals; composites; glass; industrial minerals; metals; plastics; polymers; rubber; textiles.

Working in a diverse range of industries, materials engineers combine or modify materials in different ways to improve the performance, durability and cost effectiveness of processes and products. For ideas about the range of careers in materials engineering and science, go to UK Centre for Materials Education (UKCME) .
Typical work activitiesWork activities vary according to the specific material and industry you work with, and the size of the organisation you work for, but there are a number of activities common to most posts. These include: selecting the best combination of materials for specific purposes; testing materials to assess how resistant they are to heat, corrosion or chemical attack; analysing data using computer modeling software; assessing materials for specific qualities (such as electrical conductivity, durability, renewability); developing prototypes; considering the implications for waste and other environmental pollution issues of any product or process; advising on the adaptability of a plant to new processes and materials;
working to solve problems that may arise either during the manufacturing process or with the finished product (e.g., problems caused by daily wear and tear or change of environment); y supervising quality control throughout the construction and production process; y monitoring plant conditions and material reactions during use; y helping to ensure that products comply with national and international legal and quality standards; y advising on inspection, maintenance and repair procedures; y liaising with colleagues in manufacturing, technical and scientific support, purchasing, and marketing;

At senior level, the work is likely to involve more innovative research or greater management responsibility. The latter will call for a range of additional skills that are not necessarily part of the routine work of a materials engineer.
Materials engineers are responsible for evaluating materials and creating plans and processes for manufacturing products from various raw materials. The machines they develop may be specialized for specific products. Materials engineers create machines that create products from one type of material such as metal, graphite, glass, plastic and other natural resources. As long as society needs material for construction and products that will be sold either to other consumers in or out of the country, materials engineers will be needed.
Responsibilities1. Materials engineers may analyze and interpret data or laboratory results that can cause a problem or failure within the machines. They may create their own tests and supervise existing tests on raw materials, as well as finished products to determine its quality. They take under consideration economic factors such as pollution and costs to create the best method of creating a product from raw materials. They may solve any issues within the industries of mechanical, chemical, electrical and nuclear products. They may train and supervise a technical staff in developing any materials and products for future devices or natural products. They try to find synthetic ways of replicating natural materials such as metals, glass, etc.
2. Materials engineers must have science skills, be proficient in math, technology, reading comprehension, effective communication and problem-solving skills. Analytical skills are needed to understand and interpret data from materials and machines. Advanced writing skills, researching, deductive and inductivereasoning, and interpreting information in order to convey to others are also necessary skills.

3. Materials engineers can receive a bachelor's degree in materials engineering. The materials engineer program prepares students for the mathematical and science necessary to design, develop and operate various machines to bond, extract and create natural or synthetic materials. Students may have to considerresearching various schools in the area or out of state for specific material engineer degrees.

Concrete Mixers and Concrete Mixing Methods:Introduction As for all materials, the performance of concrete is determined by its microstructure. Its microstructure is determined by its composition, its curing conditions, and also by the mixing method and mixer conditions used to process the concrete. The mixing procedure includes the type of mixer, the order of introduction of the materials into the mixer, and the energy of mixing (duration and power). To control the workability or rheology of the fresh concrete, for example, it is important to control how the concrete is processed during manufacture. In this overview, the different mixers commercially available will be presented together with a review of the mixing methods. Further, the advantages and disadvantages of the different mixers and mixing methods and their application will be examined. A review of mixing methods in regards to the quality of the concrete produced and some procedures used to determine the effectiveness. of mixing methods will also be given. To determine the mixing method best suited for a specific application, factors to be considered include location of the construction site (distance from the batching plant), the amount of concrete needed, the construction schedule (volume of concrete needed per hour), and the cost. However, the main consideration is the quality of the concrete produced. This quality is determined by the performance of the concrete and by the homogeneity of the material after mixing and placement. There should be a methodology to determine the quality of the concrete produced, but only few methods and only one attempt of standardization were found in the literature. The methodology to determine the quality of the concrete mixed is often referred to as the measurement of the efficiency of the mixer. The efficiency parameters of a mixer are affected by the order in which the various constituents of the concrete are introduced into the mixer, the type of mixer, and the mixing energy (power and duration) used. The Mixers Batch mixers Mixers that produces concrete one batch at a time, and needs to be emptied completely after each mixing cycle, cleaned (if possible), and reloaded with the materials for the next batch of concrete.
