水泥赤泥混凝土力学性能研究

Analysis of Mechanical Properties of Cement Red Mud Concrete

通过室内试验，分析研究了水泥赤泥混凝土的力学性能。认为用磨细赤泥代替１／４以下水泥用量的细赤泥混凝土，与普通水泥混凝土的抗折强度相当；与相同用量的水泥混凝土相比，掺加磨细赤泥会提高抗折强度，成本降低，而抗压强度提高不明显；用未磨细的粗赤泥代替部分砂形成的混凝土，抗折强度及抗压强度均较普通水泥混凝土低。

Through test,the mechanical properties of cement ted mud concrete is analysed. Fine red mud cement concrete,that is formed through the substitution for less than 1/4of cement with fine red mud, has same flexible strength as normal cement concrete.Compared with the cement concrete,that has the same cement content as the red mud cement concrete,the mix of fine red mud to cement concrete can increase the flexible strength,reducethe cost, but increase the compressive strength no obvious. The cement concrete, that osformed through the substitution for part of sand with coarse red mud,has a lower flexibleand compressive strength than the normal cement concrete.
