N E T ROUND CONCRETE FORM COLUMN FORMING Round Concrete Form Lightweight and easy to handle. Easily sawed to proper length on job site. Versatile and can be cut, drilled or scored for numerous construction applications. Available in a variety of types and sizes to meet different forming needs. Placing, bracing, pouring, stripping and finishing require less time and less labor. Skilled labor not required as with permanent forms. One-piece forms for a multitude of one-time uses. Concrete forms require no cleaning, reassembling or return shipping. And, you can set and pour multiple columns at one time. How to store Store concrete forms in a dry place at the job site: ♦ For best results, store forms vertically to maintain roundness. ♦ Keep ends covered at all times. ♦ If stored horizontally, elevate a minimum of 4 inches off the ground and support the full length of the forms. Placing Even the largest concrete forms are easier to place either manually with block and tackle, or by crane: ♦ Position over a reinforcing bar cage if desired. ♦ Avoid damaging the inside surface. ♦ Place individually or in groups for continuous pouring. Bracing Concrete forms require minimal bracing to be brought to plumb: ♦ Use light lumber or scaffolding. ♦ Secure the column foot with collars if necessary. ♦ If pouring bents for bridges, consider tying the column form in with the beam form. ♦ Concrete forms can also be tied into other forms or structural members. Pouring Note: Use a release agent with all forms, especially when working with aggressive concrete formulations. Concrete forms are engineered not to buckle, swell or lose shape, and have been successfully used with a continuous pour of column. Do not exceed ACI-recommended pour rates. Stripping Strip the form as soon as possible after the concrete has set to prevent concrete from sticking to the form. Recommended time for the easiest and fastest stripping is 24 to 48 hours after the pour. Concrete forms should not be left on the column for more than 5 days. Stripping options: ♦ Use a circular power saw to make two vertical cuts on opposite sides of the form. To prevent marring, make sure the depth of cut is not set too deep. Remove the form. ♦ Use a utility knife to cut the form from the top down at least 12 inches. Use a broad-bladed tool such as a shovel and short strokes to pry the form away from the column in a spiral motion. Stripped forms can be used to protect finished columns until completion of project.
