The document discusses various mechanical properties of materials including strength, stiffness, elasticity, plasticity, ductility, brittleness, hardness, toughness, fatigue, creep, resilience, and malleability. Strength is the ability to withstand load before failure. Stiffness is the resistance to deformation under stress. Elasticity and plasticity refer to a material's ability to return to its original shape or retain a deformation, respectively. Ductility allows drawing a material into a wire while brittleness causes brittle fracture. Hardness measures resistance to surface indentation. Toughness is the ability to absorb energy without fracturing. Fatigue and creep describe effects of repeated or sustained loading. Resilience and malleability

Record breaking mega structures in turkeyYasin Engin
This document lists several record-breaking mega structures that have been built in Turkey, including:
1) The Marmaray Tunnel in Istanbul, which is the deepest immersed tube rail tunnel in the world at 60 meters below sea level.
2) The Avrasya Tunnel in Istanbul, which is the world's deepest underwater road tunnel at 106 meters below sea level.
3) The 1915 Canakkale Bridge, which will be the longest suspension bridge in the world at 2023 meters long when completed in 2023.
This document lists various tests that can be performed on materials used in concrete and on hardened concrete itself. It includes tests for cement, pozzolans, fine and coarse aggregates, fresh concrete properties like slump and air content, mechanical properties of hardened concrete like compressive strength and flexural strength, and durability properties like chloride penetration, freezing and thawing resistance, and corrosion resistance. The tests are grouped into categories for hardened concrete basic tests, chemical admixture tests, fine and coarse aggregate tests, advanced hardened concrete tests, cement and pozzolans tests, and fresh concrete tests.

Examples of structures of super high-strength concrete in engineeringYasin Engin
This document summarizes properties of structures that used super-high-strength concrete, including notable buildings and bridges. It provides details on the location, year completed, dimensions, concrete strength, water-to-binder ratio, and cement/additive contents. Examples include the Petronas Towers in Malaysia with concrete strength of 85 MPa, the Laurentienne Building in Canada with strength of 120 MPa, and the Millau Viaduct in France with concrete reaching 199 MPa. The document concludes by noting that Samsung C&T is working to commercialize 200 MPa concrete to enable even taller structures.
This document lists some milestones in the history of concrete construction from 1835 to 1963, including:
- The first plain concrete house built in 1835 in Kent, UK.
- The first reinforced concrete structure built in 1848 in France.
- The first reinforced concrete bridge built in 1875 in France.
- The first reinforced concrete building built in 1892 in Paris, France.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
The document provides descriptions of 31 architectural projects from around the world that feature the use of concrete in innovative ways. Many of the projects play with the plasticity and sculptural qualities of poured and cast concrete to create dramatic curved and angled forms, while others employ concrete's durability to blend structures into their natural landscapes. A few highlights include Zaha Hadid's dynamic Vitra Fire Station, Oscar Niemeyer's parabolic columns at the Cathedral of Brasilia, and Louis Kahn's monumental Salk Institute perched above the Pacific Ocean.
Modified Methylene Blue (MMB) Test ProcedureYasin Engin
This document provides detailed procedures for performing the Modified Methylene Blue (MMB) test to determine the amount of methylene blue adsorbed by aggregate fines. The test involves mixing a sample with methylene blue solution, filtering the mixture, diluting it, and measuring absorbance with a colorimeter. A higher methylene blue value indicates higher clay content, which is undesirable for construction materials. Research has shown a strong correlation between methylene blue value and properties like strength reduction and shrinkage in Portland cement concrete containing clay-contaminated aggregates.
An old book about Portland cement and concreteYasin Engin
This document summarizes a paper presented to the Institution of Civil Engineers on Portland cement. It discusses the manufacture of Portland cement, including the raw materials of clay and chalk used. It describes the chemical processes that occur when the mixture is burned in kilns to produce clinkers. It also discusses testing of Portland cement, including chemical analysis, specific gravity measurements, and breaking strength tests of cement blocks. The document emphasizes the importance of thorough burning and grinding of cement to ensure high quality.
