Kristina Jantz August 26‚ 2013 The three essential properties of every material are these: 1. What kind of atom makes up that material? 2. How are the atoms in the material arranged? 3. How are the atoms in the material bonded together? (Trefil‚ p. 239) Atoms make up everything we can see‚ therefore every material‚ and atoms have very different properties within themselves‚ as well as having different ways of being arranged or of bonding

structures is how the building remains standing. Architects need to design structures that hold up under any combination of three physical forces; compression‚ tension‚ and bending. To days architects have a plethora of materials at their disposal‚ they benefit from the evolution of materials and have the opportunity to use them how they wish‚ but it has not always been this way. Primitive buildings were built using dry masonry‚ which is a simple technique of stacking stones in a consistent pattern

Everyday people purchase thousands of objects and live in large houses and live the ideal material life‚ with material things‚ and lives based on what they own. However there are several people all over the world that have no homes and base their belongings on what they can carry with them. Lars Eighner was found homeless and through this‚ discovered his own lessons of life by scavenging and developing the understanding the difference between those who live through their possessions and those who

Segregation is caused by * Too wet mix‚ extremely high workability or less cohesive mixture causes the mixture unable to hold heavy aggregate * Dropping from excessive height * Over compaction of fresh concrete. Two methods to minimize segregation in fresh concrete: * Adequate workability is enough. * Don’t over

structures are in structural concrete. The functional demands of such high rise structures include the use of durable materials. High Strength Concrete‚ Self–compacting Concrete are gaining widespread acceptance. Apart from the basic structural materials‚ modern projects require a variety of secondary materials for a variety of purposes such as construction chemicals‚ waterproofing materials‚ durability aids etc. The paper highlights some of the recent developments.
