Typical Physical Properties and Mix Proportions for Perlite Concrete

Table 4 - Physical Properties and Mix Proportions for Perlite Concrete
Typical Properties				Typical Mix Porportions
Cement to Aggregate Ration (by Volume)	Dry Density Range lb/ft³	Minimum Compressive Strength lb/in²	Wet Density Range lb/ft³	Cement ft³	Perlite ft³	Water Gallons	AEA
1:4	36-42	300	48-56	6.75	27	61	(a)
1:6^b	24-30	125	38-44	4.5	27	54	(a)
1:8	18-24	80	34-40	3.5	27	50	(a)
FOOTNOTES AND NOTES: (a) Consult your perlite manufacturer for recommended types and proportioning of air entraining agent. Whatever type and proportion is used, try to obtain 10-15 percent air in the wet mix. (b) The 1:6 mix ratio is the standard mix used on most roof deck applications.
