纤维混凝土立方体抗压性能试验研究

混凝土作为目前使用量最多的建筑材料,因其易取材、耐久性好等优点被广泛运用,但由韧性差、易开裂等缺点,在混凝土中掺入纤维可以改善这些缺陷.为了研究不同纤维混凝土的力学性能,制作了9组27个标准立方体试块,前5组将PVA纤维按照0,0.05％,0.1％,0.15％,0.2％的掺杂到混凝土中;后4组控制纤维总量为0.2％,将...

Experimental study on compressive performance of fiber reinforced concrete cube

Concrete is the most widely used construction material at present.Due to its advantages such as easy drawing materials and good durability,it has been widely used.However,due to its disadvantages such as poor toughness and easy cracking,these defects can be improved by adding fiber into concrete.In order to study the mechanical properties of different fiber concrete,9 groups of 27 standard cube test blocks were made.The first 5 groups incorporated PVA fiber into concrete according to the content of 0,0.05%,0.1%,0.15%and 0.2%.In the latter 4 groups,the total amount of fiber was 0.2%.PVA fiber and steel fiber were doped into concrete with the content of 1∶3,1∶1,3∶1 and steel fiber fully doped with the content of 0.2%steel fiber.Hydraulic press was used for compressive test.With the increase of steel fiber content,the compressive strength of concrete is improved.
