Which is the best grade of Corten weathering steel?
The original COR-TEN® received the standard designation A 242 ("COR-TEN® A") from the ASTM International standards group. Newer ASTM grades are A 588 ("COR-TEN® B") and A606 for thin sheet. All alloys are in common production and use.See all results for this questionWhen do you drill holes for strength testing?When drilling holes to provide access for penetrations in a finished structure, the only goal is to provide an opening of the correct size and alignment. But when drilling is done to produce cores for strength testing, the goal is to provide a core that best represents the in-place concrete.See all results for this questionWhat is the ASTM standard practice for rock core drilling?ASTM D2113-14, Standard Practice for Rock Core Drilling and Sampling of Rock for Site Exploration, ASTM International, West Conshohocken, PA, 2014, www.astm.orgSee all results for this question

lightweight concretes. The ASTM specifications related to concrete type and weight can be summarized as follows: The type and mechanical properties of concrete aggregate have a major influence on the behavior of drill bits used to drill anchor holes. Harder aggregates, in fact, cause higher bit wear and reduced drilling performance.Drilling and Sampling of Soil and Rock - PDHonline astm corten a specs Hole drillingTypes of non-core drilling include air-track drilling, down-the-hole percussive drilli ng, rotary tricone (roller bit) drilling, rotary drag bit drilling, and augering with carbide-tipped bits in very soft rocks.
