A plastic polyethylene covering retains moisture in the concrete and improves temperature control. If the temperature is below 60 F, use dark-colored plastic sheets to absorb more light and boost the temperature; when temperatures are higher than 85 F, reflective, white-colored sheets help to keep the concrete cool as it cures.
The Box or Container Industry and Poly Bag Industry are not consistent with dimension names. The dimensions referenced in this calculator for both the box and poly bag are correct and consistent with industry standards. Measure dimensions of the rectangular object (select "inches" or "mm") Width.
Use for: sidewalks, curbs, driveways, concrete floors, pool decks, patios, floors or parking decks. One 40 lb bag will cover approximately 17 Sq. Ft. of surface at a thickness of 1/4-in or approximately 90 Sq. Ft. per bag when applied at the minimum thickness with a broom or squeegee
Apr 30, 2016· When plastic sheeting or curing blankets are placed atop a concrete slab, much of the blanket is in direct contact with the concrete but there are also wrinkles and air pockets where the plastic remains suspended just above the slab. Condensed water pools wherever the plastic touches the slab, but the concrete under the air pockets remains dry.
The coverage should be written somewhere on the front or back of the bag. If you are talking about ready-mix (the kind you only add water to), a bag will cover 2 sq ft at 4" depth (1' x 2' x 4").
So for every yard of sand you get, you can expect to buy 9 bags of cement. If you plan on using bags of sand, then just calculate about 282 lbs. for every 94 pound bag of cement. Cement: Cement comes in either 47lb. bags or 94 lb. bags but for this example we are going to use the 94 lb. bags.
Mar 23, 2013· How much concrete does a 94 lbs bag of cement produce? Source(s): concrete 94 lbs bag cement produce: https://tr.im/dgZx5. 0 0. Dash. Lv 7. 8 years ago. Portland cement is just one ingredient of concrete. So if you mixed 94 lbs of cement with the right proportions of sand, aggregate, and water you could make about 4 1/2 cubic feet of concrete. 2 0.
Dec 14, 2018· For example, if you need to cover 33.333 cubic feet, using 60-pound bags of concrete, divide 33.333 cubic feet by .45 cubic feet to get 74.07 total bags of concrete.
Hi Rocknerd. Thank you for your great question. A 50lb bag of Quikrete is .375 cubic feet. Your 5 gallon bucket is 0.7777850 cubic feet dry.
Much of the work to pour concrete is done before the truck even arrives at the project. The site must be measured and laid out. Forms must be installed to create the edges of a slab or contain a footing. Rebar or fiber or steel mesh should be installed to reinforce the concrete and to prevent cracking in the future.
Plastic cement conforms to ASTM C1328 standard specification for Plastic (S tucco cement). Product Precautions: Plastic cement is intended solely for use in portland cement based plaster and stucco applications. For precise product application it is important to refer to the project specifications.
A. We use fibermesh in all the concrete floors and slabs we pour. We add 1 bag (usually 1lb.) of the micro polypropylene fibers to 1 yard of concrete. Most synthetic fibermesh products are engineered for use as concrete reinforcement at a ratio of 1.0 to 1.5 lbs per cubic yard (.60 to .90 kg per cubic meter). of concrete.

Where a more structural concrete is required you may need to add neat cement to the premixed bag. As a guide, an addition of 1kg to 1.5kg per 20kg bag of Concrete Mix can be used to achieve around 32 MPa concrete (under normal conditions). preparation Formwork made from 25mm thick timber is commonly used to mould the concrete.
Lay this form on the plastic. Mix the bag of concrete mix with the required water and mix until it's a uniform texture. Remember, you can always add more water. Add the water in stages as you mix. Pour the mixture into the form. Use a straight piece of wood to make the concrete …
We recommend rounding up on all approximations, to ensure you have enough material. Hedberg Supply does not stock all of the materials needed for Stucco Scratch Coat applications. * One shovel full of sand weighs approximately 10 to 12 pounds. ** If using synthetic stucco, use fine sand.
How much sand do I need? The first step is to establish the volume of sand needed. It is equal to the volume of excavation, and you can do it with the following method: Determine the length and width of the cuboidal excavation. For example, we can assume an excavation of length L = 12 yd and width b = 3 yd.
QUIKRETE® Portland Cement (No. 1124) complies with current ASTM C150 and Federal Specifications for portland cement. Can be mixed with aggregate and other ingredients to make concrete mix, mortar mix, and base coat stucco. Available in Type I, Type I/II and Type III. Available in: 47lb. bags - …
Mix two 50lb bags of concrete with water in a mixing tub or 5-gallon bucket. Add concrete into the hole and around the 4" x 4". Depending on your climate, let concrete set up for 24 - 48 hours.
DO cover new concrete. When you don't have time to revisit your concrete with a hose as many times as necessary for true moist curing, another option is to use a cover that can trap and slow the ...
A comment from a reader:"I notice in your section on self leveling concrete that you mention about needing to let the water out before putting anything on top of the new compound. (Self Leveling Concrete) This is a common misconception about concrete, in fact the water does not leave, it becomes part of the concrete. You could seal it with watertight plastic and the concrete will still setup ...

Feb 12, 2004· It should say so on the bag. Concrete usually covers the volume of the agregate used. The cement holds it together. Dewy, Feb 10, 2004 #2. Lightning McQueen New Member. A decent grade of concrete will have a cement content, by mass, of around 330kg/m3.
Wet the concrete, then place the plastic sheeting over it. Use bricks, boulders, or stakes to hold the plastic in place and keep small animals out. Once a day, remove the plastic sheet and wet the concrete, then replace the cover. Do this for a week for the best results.
