The Concrete Performance with Iron Tailings Sand Modified by Polypropylene Fibers under Aggressive Environment

Table 3

Mixture proportion of three concrete mixes.

Design goal	Sand (%)		Water-cement ratio	Polypropylene fibers volume fractions (%)
	NS	ITS
CI0P0	100	0	0.4	0
CI30P0	70	30	0.4	0
CI30P0.1	70	30	0.4	0.1

Note: CI30P0.1 represents 30% ITS and 0.1% polypropylene fibers.
