[956] Concrete Driveway-Concrete Driveway Secrets
|
|
Concrete Driveway is usually placed with minimal difficulty by backing the Ready-mix truck from the street to the desired location to start placement in the driveway. A 3000 lb psi. concrete driveway mix at a 5.50 depth is recommended with 3/8" steel rebar tied on 4 ft. centers to assure a strong slab. After forming the concrete driveway the sub grade is compacted using a mechanical device, Jumping Jack, Plate compactor or roller, if not compacted prior to forming. Concrete driveways are only as strong as the ground that is poured on, using steel in conjunction with compacting the driveway will greatly enhance the strength and life of the concrete driveway. A Concrete Driveway can be stamped, stained, regular gray, exposed aggregate, colored concrete or textured. Once the concrete driveway is finished, a curing compound is applied to seal the driveway for superior moisture retention, producing a harder concrete driveway.
Concrete Tools are the finisher's best friend when finishing concrete driveways, the right tools are a must in this business. Walking tools have increased efficiency of concrete finishing by reducing the amount of time and energy refining the driveway finish. The speed in which concrete can be tooled, lowers labor costs, in turn passing the saving on to the consumer. Old school books found at your public library published in the 1950's, are the preferred practice of concrete driveway placement and finishing concrete. This day and age, refining the driveway finish is more then just a Bullfloat, edger, jointing tool and broom, the innovation of walking tools allow the finisher the ability to stand upright. Using extension handles, control joints and edging can be Installed with minimal effort and speed in the driveway. Concrete driveway finishing of the surface is done in stages. On a large driveway slab, concrete is consolidated, Rodded off or (Screed), then it is Tamped. After Bleed water has minimized, the surface is then floated using a Bull float overlapping 50% each pass, then perpendicular or (right angle) 50% each pass, if possible, until covered. This will insure a level driveway surface. Once the Bull floating is completed the driveway will need time to set or may not need time. A chemical reaction between the cement paste and water is called hydration. These compounds in cement form chemical bonds with water molecules and become hydrates or hydration products. The cement needs moisture to hydrate and cure or (harden). The set time or hydration, is influenced by atmospheric conditions, wind, temperature, humidity, soil moisture content, all play a factor with aspect to hydration. When the surface of the driveway is slightly firm to the touch, a Fresno is used to refine the driveway finish using the 50% overlap each pass and perpendicular. A steel edger is used to refine the edges of the driveway slab and magnesium float is used to refine the perimeter. When the surface is firm to the touch and still moist, 5 lbs. of weight is added to the Fresno with 50% overlap each pass and perpendicular. The Edger and Steel Trowel is also used around perimeter. Once the surface holds your weight with a slight imprint of your shoe, a total of 10 lbs is added to the Fresno for the last pass with 50% overlap. Edger and Steel Trowel are also used around perimeter to refine the driveway finish. After finishing the concrete driveway slab to a refined finish the hydration reaction continues, moisture needs to be retained in the slab to achieve maximum strength. A curing compound such as Slow Con is used to seal the surface with a non-wax clear water base coating. Concrete driveways can also be cured by submerging the slab in water or watering the slab with a sprinkler. Concrete Patio installation is usually placed using wheel borrows or a concrete pump, the added cost is slightly higher then a driveway. Patio installation practices, compaction,. |
