Post-tensioned concrete slab with fibers
A concrete slab (20) comprises conventional concrete and is reinforced with a combination of post-tensioned steel strands (22, 26) and fibers (29). The post-tensioned steel strands (22, 26) have a diameter of 5 mm to 20 mm and a tensile strength of more than 1700 MPa. The use amount of the fibers (29) in the case of steel fibers is from 10 kg/m < 3 > to 40 kg/m < 3 >, and the use amount of the fibers (29) in the case of coarse-synthetic fibers is from 1.5 kg/m < 3 > to 9.0 kg/m < 3 >.
一种混凝土板(20)，包括传统混凝土并采用由后张钢绞线(22，26)与纤维(29)实现的组合加固。所述后张钢绞线(22，26)：‑直径为5mm至20mm，‑抗拉强度高于1700MPa。所述纤维(29)在钢纤维情况下的用量为10kg/m3至40kg/m3，在粗‑合成纤维情况下的用量为1.5kg/m3至9.0kg/m3。
