Safety of engineered structures against blast vibrations

2016-4-1 & 0183; The damaging level of PPV V PD for a given age of concrete can be obtained by multiplying V c estimated from Eq. by 160. By adopting a suitable safety factor for Eq. and estimating V c from Eq. , site-specific safe vibration levels could be evaluated for green concrete of ages varying from 1.25 days to 7 days. In practice, freshly placed concrete is subjected to mechanical vibrations to eliminate voids …

Mining with Backfill - QueensMineDesignWiki

Sources of BackfillPaste Fill vs. Hydraulic FillFill Delivery SystemsEconomical EvaluationBulkheadsReferencesThere are various sources used by mines for backfill material. Mines normally make their choices based on what is locally available and most economical. Mine tailings are widely used in today’s industry, as they result in the lowest cost.This is because tailings are available, and the use of tailings underground requires smaller tailings treatment and impoundment facilities on surface. Also, using tailings eliminates the need to transport …在minewiki.engineering.queensu.ca上查看更多信息

101 facts about Costain Costain

Six 30,000 tonne concrete tunnel segments were sunk into position on the Conwy riverbed by the Costain joint venture - to a tolerance of 10 millimetres. Costain built the Skylon and Dome of Discovery for the 1951 Festival of Britain. Costain has produced more than 50 million precast concrete railway sleepers since commercial production began in 1943.

Damage Mechanism of Mineral Admixture Concrete under

AbstractIntroductionMaterialsExperimental Methods and SchemeResults and DiscussionConclusionsAcknowledgmentsUnderstanding the performance of concrete in the marine environment is significant for preventing the corrosion of chloride ion for marine buildings. In this study, the uniaxial compressive strength UCS , chloride ion concentration CIC , microstructure, and pore structure of admixture concretes were tested to study the mechanical properties and microscopic characteristics under the single marine corrosion, the single freezing-thawing, and the coupled marine corrosion and freezing-thawing conditions. The results …
