bar-to-bar test
2.TRIAL TEST TO DEVELOP B400SD and B500SD REINFORCED BAR ACCORDING TO STANDARD OF UNE36065EX
5.In light of great harm from alkali-aggregate to concrete, the alkali activation of the limestone to be used as the aggregate for the concrete in the construction of Zhangfeng Reservoir is fully tested with petrographic method, accelerated mortar bar method and autoclave expansion test etc., so as to ensure the durability of the anti-abrasion concrete therein.
10.The test results indicated that: crack similitude of reinforced concrete simple beams is not equal to model scale λ under the working load; when the amount and surface shape of reinforcing bar are same, the similitude of crack width, crack amount and crack spacing of reinforced concrete simple beams of different scales are all nearly equal to the square root of model scale√λ; when the amount and surface shape of reinforcing bar are different, the similitude of crack amount and crack spacing are still nearly equal to√λ, whereas the crack width is not only approximately proportional to√λ, but the influence of the amount and surface shape of reinforcing bar on crack width should be considered also at the same time.
