将膨润土按一定置换水泥的比例加到混凝土中,开展混凝土的抗压、抗折强度试验,研究膨润土对混凝土的强度的影响。试验表明,随着养护天数的加大,膨润土混凝土的抗压、抗折强度均成增大趋势,但随着膨润土含量的加大,混凝土的抗压、抗折强度均有所减小,膨润土含量最大的混凝土试样,抗压、抗折强度最小;混凝土中少量的添加膨润土,其强度减小幅度不大。 Bentonite by certain proportion of replacement cement added to the concrete, to carry out the compressive strength of concrete, bending strength test to study the impact of bentonite on the strength of concrete. The test shows that with the increase of curing days, the compressive strength and flexural strength of bentonite tend to increase, but with the increase of bentonite content, the compressive strength and flexural strength of concrete decrease. The bentonite The content of concrete samples with the lowest compressive strength and flexural strength is the least. The addition of a small amount of bentonite in concrete reduces the strength by a small amount.
