Can I use it to fix cracks in driveway?

Yes, QUIKRETE® Quick-Setting Cement (No. 1240) can be used to fill cracks in a concrete driveway. If the cause of the cracking has not been remedied (such as poor subgrade that causes movement of the slab), then cracking will continue through the repaired sections. QUIKRETE® Quick-Setting Cement (No. 1240) is specially formulated to set in approximately 10–15 minutes. Do not mix more product than can be used in 10 minutes. Where large quantities of material are needed for deep patches, QUIKRETE® Quick-Setting Cement can be extended with up to 10 lb of 3/8" maximum size aggregate per 20 lb bag. When making repairs, getting a good color match can be difficult - we always recommend trialing a small quantity of the repair material in a discrete area, and allowing it to cure for one week to determine whether the color and overall appearance are acceptable before using the material in less discrete areas. If you are looking for a more flexible crack filling material you may want to consider the QUIKRETE® Polyurethane Self-Leveling Sealant (No. 8660) or the QUIKRETE® Polyurethane Concrete Crack Sealant (No. 8620-17).
