Extension: what type of rock is used to make concrete?
Ceramics and compositesSlide2
CeramicsCeramic materials:are solids made by baking a starting material in a very hot oven or kilnare hard and toughhave very many different usesSlide3
Advantages and disadvantagesProsHard and withstand pressure ConsBrittle Slide4
CompositesComposites are a mixture of materials Reinforced concrete is a good examples of this, it contains steels and concrete.This gives it the best of both materials, it is:strong when stretched (because of the steel)strong when squashed (because of the concrete) Slide5
Testing concrete and reinforced concreteYou will be provided with three materials, two composite concrete materials and cement .You should test how well they withstand impacts. (either repeated OR increasing mass)Before you begin you should consider the risk and the waste products. Slide6
Other composites Waterproof membranesCarbon fibre A composite material (also called a composition material or shortened to composite, which is the common name) is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual Slide7
Plotting of graphs. CompressionPresent this data in a graph. You should use a bar chart, but need to display both sets of data from each sample on the same graph. Which sample of composite would you choose in the structure of a building?Slide8
Plenary How do composite materials help us?Produce a 30 second sound bite on the use of composites in modern day life.
