Function Synergy of Cross-Linked Cationic PVA Polymer to AMPS-Type Fluid Loss Additive Used for Cement-Based Material

Table 5

Fluid loss test (comparison for SXY-2 added).

Test no.	PVAGB (%BWOC)	FLA A (%BWOC)	SXY-2 (%BWOC)	Fluid loss (mL) (30 minutes)
9	0.2	1.0	0.50	34
9	0.2	1.0	0.75	30

Note: test condition as 30°C, 6.9 MPa, and fluid loss in 30 minutes.
