Investigation on the Mechanical Properties and Microscopic Characteristics of Modified Steel Slag Concrete under Sulfate Erosion

Table 1

Mixture ratio of modified slurry (kg).

Serial number	Water cement ratio	Water	Cement	The fly ash	The test phenomenon
1	0.3	10	11.1	22.2	Difficult to fill pores; Surface adhesion is strong
2		10	8.3	25
3		10	6.7	26.6
4	0.5	10	6.7	13.3	Slightly less filling
5		10	5	15	Effective void filling and adhesive
6		10	4	16	Adhesion is weak
7	0.6	10	5.5	11.1	Too dilute; Can fill the pores with poor adhesion
8		10	4.2	12.4
9		10	3.3	13.3
