What PSI is 5.5 sack?
3000 psi
What does 6 bag mix mean in concrete?
A six bag mix is a concrete mix that has six bags of portland cement in it. In general, the more bags of cement in a mix, the stronger the mix. Most mixes have 5 to 7 bags of cement. Some concrete contractors (usually the old timers) will order their concrete based on bags rather than psi.
What is the strongest type of cement?
High-strength concrete has a compressive strength greater than 40 MPa (5800 psi). In the UK, BS EN 206-1 defines High strength concrete as concrete with a compressive strength class higher than C50/60. High-strength concrete is made by lowering the water-cement (W/C) ratio to 0.35 or lower.
What is 5000 psi concrete used for?
Used in special construction applications, including some large-scale commercial and industrial properties, 5,000 PSI can withstand heavy impact and extreme wear and tear.
Is gravel necessary under concrete?
Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn’t drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains.
Can you pour concrete over grass?
Cheap and versatile and easy to pour, concrete will last you years down the road. You can pour it just about everywhere—including on the grass. Although it takes a little work, pour concrete over grass to create that walkway you always wanted or that mowing preventative you could previously only dream about.
Should you put plastic under concrete?
A concrete vapor barrier is any material that prevents moisture from entering a concrete slab. Vapor barriers are used because while fresh concrete is poured wet, it’s not supposed to stay that way. It needs to dry and then stay dry to avoid flooring problems. This is why a vapor barrier under concrete is essential.
Do you need rebar for 4 inch slab?
No, you do not need rebar for a 4-inch slab of concrete on grade. A 4-inch-thick slab cast on the ground and in permanent contact with it will float and rebar is not required. Rebar is recommended on concrete measuring 5 – 6 inches thick.
How much does it cost for a 20×20 concrete slab?

Do you need a vapor barrier on concrete?
You’ll typically need a vapor barrier if you’re installing flooring over concrete. Therefore, in high-humidity areas, moisture will move to a relatively low-humidity area, even through concrete. This way you can stop the vapor drive of water upward to your floors, protecting them from any damage (source).
Where do you need a vapor barrier?
In the event you are erecting a “cold building” (such as a refrigeration building) that stays at 32 F (0 C) degrees or less inside, you will need a vapour barrier on the outside of the insultation to prevent warm exterior air from entering and potentially damaging the roof’s insulation.
Where do you put a vapor barrier?
Vapor barriers are usually best installed on the side of the wall that experiences the hotter temperature and moister conditions: the inner surface in colder climates and the outer surface in hot, humid climates. In existing spaces, oil-based paints or vapor-barrier latex paints offer an effective moisture barrier.
How thick should a vapor barrier be?
6 mil
Is 4 mil plastic thick?
1 MIL is a measurement unit that equals 0.001 inch which is about the width of an average human hair. Generally speaking, higher MIL designation equates to a thicker and strong plastic sheathing. The most common plastic sheeting sizes found in local hardware stores are 2, 3, 4 and 6 MIL poly sheets.
Can I use plastic sheeting as a vapor barrier?
In simple terms, a vapor barrier is a material that won’t allow moisture to pass through it, such as plastic sheeting. A very simple experiment to show how a vapor barrier works is to lay a plastic garbage bag down on some damp soil. There are two basic types of vapor barriers used with exterior wall insulation.
What is the thickest clear plastic sheeting?
The most common size in the thickness rating for plastic sheeting is 6 mil. This is 6-thousandths of an inch, or 0.006 inch. Generally, the thicker the plastic, the stronger it is. If it has string/scrim reinforcement, then the string within the plastic will give it added strength.
What is the clearest plastic?
Acrylic
What is clear hard plastic called?

What is the difference between acrylic and plexiglass?
We can give a short answer to this: there is absolutely no difference. This is because acrylic is the usual abbreviation for polymethyl methacrylate, and Plexiglas® is one of the many brand names of this plastic. Over time this brand name has become generic as ‘plexiglass’.
Can I use perspex instead of glass?
Acrylic sheets can be used as greenhouse plastic, playhouse windows, shed windows, perspex mirrors airplane windows etc. as an alternative to glass. Light transmittance – Acrylic sheets transmit up to 92% light, while glass can only transmit 80-90% light.
Is glass cheaper than plexiglass?
Glass tends to cost less than plexiglass, and can be more scratch resistant and more easily recycled. In general, long-term maintenance and replacement costs can be significantly cheaper with plexiglass.
How much force does it take to break plexiglass?
In most applications, acrylic is shatterproof with “six to 17 times greater impact resistance than normal glass” reports rplastics.com, able to withstand a compressive impact equal to 18,000 lbs per square inch (psi).
Is glass cheaper than acrylic?
While glass is cheaper to purchase and more easily recycled than acrylic, acrylic is stronger, more shatter resistant and resistant to the elements and erosion than glass. Depending on how it is manufactured, it can be either more scratch resistant than glass or extremely scratch- and impact-resistant.
Does Lowes cut glass to size?
