The requirements of ASTM C1550-10a for determining flexural toughness of fiber reinforced concrete (FRC) create several challenges for most standard test systems in service today. Specifically: ?Size of the specimen: With a diameter of 800 mm (31.5 in) most existing load testing frames do not have the test space width to accomodate this. 英斯特朗1000HDX 英斯特朗DX系列液壓wan能材料試驗(yàn)機(jī) 英斯特朗HDX系列大載荷液壓wan能材料試驗(yàn)機(jī) 英斯特朗MDX系列大載荷液壓wan能材料試驗(yàn)機(jī) 英斯特朗1000HDX大載荷液壓wan能材料試驗(yàn)系統(tǒng)
