Today, aluminum is recognized as one of the most energy efficient and sustainable construction materials. The estimated recycled content of aluminum building materials used today is between 50 and 85 percent. Aluminum-intensive LEED-certified buildings have won awards for Platinum, Gold and Best-in-State sustainability across the country. Biomineralization and Successive Regeneration of Jan 15, 2020 · Living building materials (LBMs) were engineered using photosynthetic cyanobacteria and an inert sand-gelatin scaffold. Microorganisms biomineralized LBMs with calcium carbonate, which imparted higher fracture toughness compared with no-cell controls. The microorganisms maintained relatively high viability in LBMs as long as sufficient humidity conditions were provided.
- AbstractIntroductionMethod and MaterialsResults and DiscussionsConclusionsAcknowledgmentsBecause of industrialization growth, the amount of coal power plant wastes has increased very rapidly. Particularly, the disposal of coal bottom ash (CBA) is becoming an increasing concern for many countries because of the increasing volume generated, the costs of operating landfill sites, and its potential hazardous effects. Therefore, new applications of coal bottom ash (CBA) have become an interesting alternative to disposal. For instance, it could be used as a Portland cement constituent leading to more Effects of Freeze and Cyclic Load on Impact Resistance of Apr 16, 2019 · Filling layer self-compacting concrete (FLSCC) is a key material in newly-built China Rail Track System (CRTS), which is commonly subjected to cyclic dynamic load from high-speed train and various ambient temperature during service. In this paper, a series of indoor simulating experiments was conducted to investigate the impact resistance of FLSCC suffering from cyclic flexural load and

Effects of High Temperatures on the Physical and Fires are always known for seriously deteriorating concrete in structures, especially for those with certain carbonation due to long-time service. In this paper, 75 prism specimens were prepared and divided into four groups (three carbonated groups and one uncarbonated group). Specimens were tested under different temperatures (20, 300, 400, 500, 600, and 700°C), exposure times (3, 4, and
It was found from the results achieved that the compressive strength, static modulus of elasticity, splitting tensile strength and toughness are extremely affected by the geometry of fibers because the network of fibers formed and their density depends on the size and shape of fibers.
