Place the QUIK-Tube into the hole and level the form. TIP: it is best to use the uncut end of the tube for the top of the footing. Step 6 Add the concrete mix to the form. After half of the form is filled, consolidate the concrete with a piece of rebar or a shovel to eliminate voids and air pockets. Step 7
Prior to placing concrete forms: Construct the form with 2x4 or 2x6 lumber and secure in place by wood stakes and deck screws. Excavate the slab area to a depth of about 7 inches, allowing 3 inches for a gravel base and 4 inches for concrete. Step 2 Check the forms for level (¼ inch for every 12 feet is sufficient to allow for rain run-off).
Jul 14, 2009· The forms should be coated with a form-release compound (ordinary motor oil will suffice) so that the forms are easily removed when the concrete has set.

Jul 13, 2010· Starting with a solid foundation for your pour is the most crucial step. When handling concrete inside its form, weather, humidity, and the sun can all be factors. Having concrete sections can cut back on some of these problems for a better outcome. Concrete sections can make a large project easier to manage. Longevity
Drill the special-size pilot hole (see package for exact bit size) and drive the concrete screw''s super-hard, large profile threads into the concrete with a power screwdriver. Buy 3/16-in. dia. screws for lighter-duty and 1/4-in. dia. screws for heavier jobs.
asphaltic concrete — a mixture of asphalt cement and aggregate. atmospheric-pressure steam curing — steam curing of concrete products or cement at atmospheric pressure, usually at maximum ambient temperature between 100 to 200°F (40 to 95°C). autoclave — a high-pressure steam vessel.
A floor screed is usually a cementitious material made from a 1:3 or 1:4.5 ratio of cement to sharp sand. It may be applied onto either a solid in-situ concrete ground floor slab or onto a precast concrete floor unit. There are many proprietary screeds on the market and information about these can be obtained from the manufacturer. Application
Manitoba by the 1870s, these basic materials gave way to manufactured building materials: milled lumber, brick, concrete block, glass block and formed metal. And while the basic principles involved in their construction can still be seen, the sophistication involved in the production of these new materials …

Concrete is prepared by mixing cement, water, and aggregate together to make a workable paste. It is molded or placed as desired, consolidated, and then left to harden. Concrete does not need to dry out in order to harden as commonly thought. The concrete (or specifically, the cement in it) needs moisture to hydrate and cure (harden). When concrete dries, it actually stops getting stronger.
