SCC mixtures typically have a higher paste volume, less coarse aggregate, and higher sand-to-coarse aggregate ratio than typical concrete mixtures.
SCC mixtures can be designed to provide the required hardened concrete properties for an application, similar to regular concrete.
The development of high performance polycarboxylate polymers and viscosity modifiers have made it possible to create “flowing” concrete without compromising durability, cohesiveness, or compressive strength.
The flowability of SCC is measured in terms of spread when using a modified version of the slump test (ASTM C 143).
But its latest exit suggests Uber is more than ever dependent on its home market of North America, not unlike Khosrowshahi’s previous U.
S.-centric employer, Read more: Grab CEO Braces for a Fight of Biblical Proportions With Uber Grab, which started out as a taxi-hailing app in Kuala Lumpur in 2012, became the region’s dominant ride-hailing service in past years with billion raised from investors.
But the deal marks the latest retreat by the world’s most valuable startup from a rapidly expanding arena: Uber committed to other key markets such as Japan and India.It was most recently valued at billion, according to CB Insights.Today, with more than 86 million mobile app downloads, it offers a wide range of ride-hailing services in 191 cities across Singapore, Indonesia, the Philippines, Malaysia, Thailand, Vietnam, Myanmar and Cambodia.Concrete Concrete Concrete Decorative Architectural Concrete Flowable Green Green Roof Pervious Roller Self Consolidating Self-consolidating concrete, also known as self-compacting concrete (SCC), is a highly flowable, non-segregating concrete that spreads into place, fills formwork, and encapsulates even the most congested reinforcement, all without any mechanical vibration.It is defined as a concrete mix that can be placed purely by means of its own weight, with little or no vibration.
