DOSAGE
A function of the required expansion as determined and specified by the design engineer based on the requirements of ACI 223. A general rule for most projects is to replace 8% -10% of the cementitious material in the mix, by weight, of Green Canvas Expansive Concrete to a standard mix design, thereby allowing use of ACI's statistical history method for mix design approval.
SHELF LIFE
We custom manufacture GreenCanvas for each shipment. The shelf-life of is less than that of cement. Recommendations are to use all material within two months of receipt in bulk. GreenCanvas in pails can be stored year and half. Packaging procedures for quality assurance require custom manufacturing of GreenCanvas for each shipment. The shelf-life of GreenCanvas is the same or less than that of cement. For large orders plan to order 4+ weeks before placement date for production & best rates/shipping.
COST
Vary depending on the type and location of the project. While adding GreenCanvas to the concrete mix does increase the price of the concrete but the ability to place larger monolithic pours eliminates many contraction and expansion joints. The cost of putting in joints and filling them is typically much higher than the extra cost of the component.
STORAGE
Clean and dry. GreenCanvas is sensitive to humidity, free water, and CO2 and should be stored and handled in the same manner as Portland cement. Keep in the correctly sealed, original package and in a dry location. Water-soluble bags can be mixed in trucks without disposal concerns (follow mixing directions).
PAILS
Water Soluble Bags shipped and stored in pails, may be stored up to one year when adequately sealed.
WATER SOLUBLE BAGS
Use all material within two months of receipt.
BULK
Clean, dry, dedicated silo. Use all material within two months of receipt.
