The Effect of Variability in the Powder/Liquid Ratio on the Strength of Zinc Phosphate Cement

Table 1

Extreme powder/liquid mixing ratios & corresponding mean diametral tensile strength.

	Maximum	Minimum	Mean	Manufacturer’s
Powder/liquid ratio, m/m (SD)	2.386	1.018	1.644 (341)	1.718
Diametral tensile strength, MPa (SD)	7.19 (1.50)	2.65 (1.01)	—	6.01 (1.30)
