Save time and money with a small mixer and some elbow grease. Recently, I mixed and poured a yard of concrete for the footing of a small addition with the help of a friend, who made it a point to remind me that there were big, clunky trucks that will bring concrete to you all mixed and ready to go.
How much does it cost to pour a concrete driveway?
In terms of cost, concrete resides in the middle of the pack, at about $5 to $7 per square foot for a basic gray slab (installed), or about $3,600 for a standard 16-x-38-foot driveway. Doing the work yourself might save you half of that cost—let's say a savings of $1,800 to $2,000.
Can you mix your own sand and gravel?
Transporting the sand, gravel, and bagged cement requires a pickup truck with a bed that seals tight. To mix your own concrete for footings and piers, use 1 part Portland cement, 2 parts clean river sand, and 3 parts gravel (maximum of 1 inch diameter and specially washed for concrete mixing).
What kind of cement do you use to mix concrete?
The industry standard uses a 1-2-3 formula with one part portland cement, two parts sand, and three parts aggregate for a 4,500-psi mix. Adding 50% more portland cement increases the strength to more than 5,000 psi. Mixing concrete is actually as easy as 1-2-3.
Once a plant’s roots discover a microscopic crack in the concrete, they force their way into the slab. Even small weeds and seedlings have the power to displace concrete …
If too much is added to the mix, the concrete’s workability will suffer, and some of the aggregates won’t properly bond to the cement. If too much is used versus the …
If you're new to the world of concrete staining, you might be wondering about the difference in cost between acid stains and other options such as concrete paints, epoxies, dyes, etc. Epoxy can range from $2 to $5 per square foot; while concrete paint typically ranges from $1.45 to $3.
Thereof, is it cheaper to make your own paving slabs? Standard concrete slabs are generally lower in cost per square foot than the alternative. Typically, you will pay 10%-15% more if you choose paving stones over standard concrete slabs.
Subfloors for Concrete A decorative concrete flooring material can be installed over an existing concrete slab, a plywood subfloor or a 3/4-inch solid hardwood flooring. When it comes to solid wood, both strip and plank flooring are acceptable as long as they are in good condition.
Concrete screws are a quick and convenient way to fasten to concrete. The best thing about these screws is that you can screw directly into concrete without any need for hammering or an anchor or shield to install. All you have to do is drill a hole and drive in the screw.
Currently, more than 50 percent of the concrete placed in the U.S. contains fly ash. 2 Dosage rates vary depending on the type of fly ash and its reactivity level. Typically, Class F fly ash is used at dosages of 15 to 25 percent by mass of cementitious material, while Class C fly ash is used at dosages of 15 to 40 percent. 3
Hydraulic lime usually gains strength in time greater than the time in which cement concrete gains same value of strength. Lime cement takes a long time to cure, and while the ancient world had lots of time, today time is money. Lime cement does not harden in water but stays soft. So there are situations where it cannot be used.
Use a sledgehammer for thin slabs. If your concrete is 4 in (10 cm) thick or less, try using a sledgehammer. Start at any existing cracks or at a corner or edge, and keep in mind that thick concrete will be easiest to break closer to its outer edges.

WD – 40 is specially formulated to be a penetrant, so when you spray it on a rusted surface, it gets to work right away by getting under the rust.
It's readily available in nature. Or you can buy it online. According to the article by the link above adding magnetite to the concrete will make it 60% more dense. This way you can make weights of the same size heavyer.
Can you fill a pothole with concrete? Remove large chunks of broken concrete and sweep out the hole with a stiff broom; flush it thoroughly with water from a garden hose. Then remove standing water with a sponge. Mix ready-mix concrete according to the manufacturer's instructions; use sand mix for small holes and gravel mix for large or deep ones.
Reinforced concrete has a high compressive strength compared to other building materials. Due to the provided reinforcement, reinforced concrete can also withstand a good amount of tensile stress. Fire and weather resistance of reinforced concrete is fair. The reinforced concrete building system is more durable than any other building system.
What does acid wash do to concrete? Acid washing , also known as acid etching, prepares a concrete surface to accept a sealer. You can also use acid in weaker concentrations to remove white mineral deposits (efflorescence) and heavy grime.
Can you put a trampoline on concrete? The answer is simply: yes. However, it is always a bad idea to set up your trampoline directly on a concrete surface. Therefore, you will need to purchase a soft rubber base for trampoline to protect both your trampoline frame and your warranty.

Like concrete, asphalt is an aggregate material of a mixture of stone and sand, but it contains tar-like petroleum instead of cement as the adhesive base. Contractors use high temperatures to liquefy hot mix asphalt and create the driveway before it cools and becomes a solid.
The development length can be defined as the length of the bar required for transferring the stress into the concrete. In other words, development length is the quantity of the rebar length that is actually required to be enclosed into the concrete to make the desired bond strength between two materials and furthermore to produce required stress in the steel at that area.
