Plastic cracking of concrete such as plastic settlement and plastic shrinkage cracking is directly related to the bleeding of concrete, which is a natural time-dependent process in a fresh concrete mix. A portion of the mixing water together with very fine materials finds its way to the surface of the concrete during this process. The rapid rate of initial bleeding slows down with the elapsed t...

The early age shrinkage is responsible for the early age cracking of concrete. It is very critical for durability of concrete. The change in volume of concrete due to evaporation of water or dehydration process is known as shrinkage. To reduce the early age shrinkage utilized the supplementary cementitious material (SCM) in concrete. In present research industrial and agricultural waste byprodu...

because thin plate reinforced concrete members such as walls and slabs are greatly influenced by the drying shrinkage, cracks can occur in these members due to the restraint of the volume change caused by drying shrinkage. therefore, the control of cracking due to drying shrinkage is very important in building construction that the thin plate members are frequently used. however, few researches...

This research assessed the shrinkage behavior of mortar containing recycled sand generated from aerated blocks and clay bricks by replacing natural with a volume ratio 30%. Five mix proportions were prepared to cast plate specimens. They named as control, ABs1, ABs2, CBs1 CBs2. Among them, ABs1 CBs1, respectively, have same water/cement control. ABs2 CBs2 had workability control adjusting requi...

With the development of plastic surgery techniques, computer aided approach has become a significant method in medical plastic surgery. In order to solve effects on surgical results made by the surface of a wound in craniofacial cosmetic surgery, accurate preoperative preparation is usually required for the surgery. This paper summarizes the application of computer aided technology in craniofac...

Sand production encountered in the 2013 offshore field gas tests at Nankai Trough, Japan, could be attributed to well failure during reservoir compaction. In this study, integrity under various compaction patterns for Trough case is examined using a well-formation finite element model. The modelling details include inclusion of cement sheath as construction processes (such shrinkage). Well elon...

Hot rolling is an essential process for the shape-forming of bearing steel. It plays a significant role in formation and distribution flow lines. In this work, effect lines investigated by analyzing microstructure mechanical anisotropy hot-rolled was found that carbides rich with Cr Mn elements are distributed unevenly along flow-line direction Moreover, characterization indicates ultimate tens...

Silica aerogels display exceptional properties and great application potential, with a mature market in thermal insulation. Both supercritical drying (SCD) ambient pressure (APD) routes are implemented industrially. Herein, how aging silica content affect the mechanical properties, these turn determine shrinkage, spring back, density during APD systematically investigated. The densities U-shape...
