High-ductility concrete and preparation method thereof
The invention discloses high-ductility concrete and a preparation method thereof.Defect generation substances are added into a high-ductility concrete matrix, the defect generation substances are self-made zeolite or self-made foaming components, the defect generation substances and the self-made zeolite or the self-made foaming components are mixed to be uniform, and the defect generation substances generate defects with the volume fraction of 1%-9% in the high-ductility concrete matrix; and the bending strength is greatly improved on the premise that the compressive strength is slightly sacrificed. The high-ductility concrete disclosed by the invention can effectively control the development of cracks, can maintain relatively high bearing capacity after cracking, and can show greater deformability when bearing external force, so that the anti-seismic and anti-impact capabilities of a structure are improved. Due to excellent durability and damage resistance, the high-ductility concrete is suitable for constructional engineering in various severe environments, and the service life of a building is prolonged.
本发明公开了一种高延性混凝土及其制备方法，通过在高延性混凝土基体中加入缺陷产生物，缺陷产生物为自制沸石或自制发泡组分，将二者混合均匀，使缺陷产生物在高延性混凝土基体中产生体积分数1%‑9%的缺陷，在小幅度牺牲抗压强度的前提下大幅度提升弯曲强度。本发明的高延性混凝土能够有效地控制裂缝的发展，在开裂后能保持较高的承载力，能够在承受外力时展现出更大的变形能力，从而提高结构的抗震和抗冲击能力。由于其出色的耐久性和抗损伤能力，高延性混凝土适用于多种恶劣环境下的建筑工程，提高了建筑的使用寿命。
