reacting with products formed during thehydration of cement. Equations 1 and 2 show the hydration reactions of portland cement.Calcium silicate hydrate (C-S-H) is the major contributor to concrete strength. SCMs such asslag cement and fly ash contain amorphous silica (S) which reacts (Equation 3) with calciumhydroxide (CH) to form additional C-S-H thereby improving strength. The equations shownbelow are in ceramic notation. 2C3S + 11H → C-S-H + 3CH (1) 2C2S + 9H → C-S-H + CH (2) CH + S + H → C-S-H (3)In addition to improving hardened concrete properties, SCMs are also used to produce “green”structures.

as change of state. Electro- and magneto-rheological fluids, for example, canchange viscosity over many orders of magnitude upon application of an externalmagnetic or electric field. This change of state has the potential to revolutionize thecontrol aspects and responsiveness of hydraulic power transmission.Research during the 1960’s and 70’s was focused on devices such as: satellite antennas(NASA) that would unfold and expand when exposed to the heat of the sun; engines thatwould run on hot and cold water; automatic temperature-controlled greenhouse windows; Page 11.922.2and car fan clutches that would engage only when the engine warmed-up.One of the

. What strength is required for the part to perform adequately? What is the part’s strength (based on hardness readings)?Deliverable 4: Describe the composition of the part. This should be a concise summary of any material characterization work done in the laboratory. Photos of the failed part and pictures of comparable microstructures should be included.Summary: Based on what was learned from each of the deliverables, explain the reason(s) for failure and how it could be prevented in the future, or explain why failure should not be prevented.Several aspects of the projects have remained constant throughout:• Students work in teams of 2 or 3, all from the same lab section• The project is divided into a final summary and four intermediate

scaleapplications within the military sector during WWII and the late 1940’s and early 1950’s. Theunique combination of performance benefits offered by composite materials has now propelledits use into almost every industry sector within today’s global economy. Composites or morespecifically, Fiber Reinforced Polymers (FRP), consist of a polymer matrix, usually a thermosetplastic and a variety of reinforcements, including glass, carbon (graphite) and aramid (Kevlar)fibers. It is this unique combination of complementary properties that, when combined, create anentirely new material with very specific characteristics. This makes the design and use ofcomposites more desirable than some of the more traditional materials in many different

A2 is the probability of being accommodated in the other grain, n1 the number of atoms in grain 1 in position to make the jump, p 1 the vibrational frequency of an atom in grain 1. ̇ Geometrical approximations is a common technique used to calculate grain size an also the effect of second-phase particles in grain growth. Here, the force (P) is applied by the particle to grain boundaries. The model assumes the particles as spheres and boundaries as lines or surfaces. P ? r r sin(2s )i where P is the force, s is the angle with the grain boundary, r is the particle

volume ratio increases—at the nanoscale, this ratio is huge. learning goals 1 - The physical form of a solid influences the degree to which it interacts with its environment: the smaller it is in three, two, or one dimension(s), the more readily it interacts. 2 - The magnitudes involved with the nanoscale can be represented with powers of 10 and scaling. 3 - The surface area to volume ratio changes with the shape or size of an object. This ratio changes dramatically in the nanoscale.There is a section for each learning goal. Each of the three sections begins with anintroductory article about something familiar, yet describing an aspect

Page 11.1387.3When asked to straighten the tubing, each student immediately feels the increased resistance,which is further enhanced for those able to bend and straighten the piece more than once. Moststudents are surprised and impressed by the large force required for straightening. The tubing islong enough so each student can try a second time, now knowing what to expect, using the otherend of the piece. After experiencing the effect of cold-work on the copper, students use pliers tohold the worked region(s) in the flame of a propane torch. The tubing is heated until it is red hot,then cooled completely under cold water
