| 摘 要： | 采用普通原材料,通过正交试验,研究了粉煤灰掺量对混凝土强度的影响,并给出了大掺量粉煤灰混凝土优选配合比。试验结果表明:粉煤灰掺量不是影响混凝土强度的主要因素;采用32.5R普通硅酸盐水泥、粉煤灰和常规减水剂可以配制强度为60 M Pa混凝土,其粉煤灰掺量可达50%。

| Abstract: | In this paper the concrete with large percentage fly ash was investigated by using ordinary materials,through orthogonal test.And the optimal mix proportions were recommended.The results show that: fly ash percentage is not the key factor of concrete intensity.By using 32.5R ordinary portland cement,fly ash and ordinary plasticizer,the fifty percentage fly ash concrete with intensity of 60 MPa can be produced. |

| Keywords: | orthogonal test fly ash concrete |
