In this section, we want to talk about how to make your own concrete blocks. These are great for making concrete structures such as paving stones, garden walls and many other things. They are also quite easy to make, with a few basic items that you should have around your home already.
The first thing that you will need is a large plastic tub. You can use a regular old bucket, but it makes more sense to use something that has good drainage and can hold quite a bit of dirt. You will also need some sandpaper or sanding paper, depending on the size of the blocks that you want to make. Some people use sandpaper while others choose to use an actual piece of plywood glued down with waterproof glue so that it gets stuck on the bottom of the bucket instead of just floating around in there.
You will also need a screwdriver and some sort of moving device (such as a shovel or rake) in order to get the dirt out of the bucket without breaking it open too much. Next you will want to find an area where you can dig out a hole big enough for the cement mixture that you are going to be using. This hole should be at least half a foot deep and should be wide enough for all of your tools and equipment
If you want to make your own concrete, it is a good idea to learn a bit about how it works. It can save you money and help you get the right results.
Concrete is formed by mixing water, sand, gravel and a type of cement which acts as a bonding agent.
After the mixture has been poured into its desired shape, it will harden due to a chemical reaction known as hydration. The water used in the mixture is chemically bound with the cement when this process takes place.
Wet the soil thoroughly and then tamp it down. Use cement at a rate of 8 shovels per cubic yard of soil. Mix the cement into the top 4 inches of soil by working it in with a rake or hoe. Rake the top 6 inches level and wet it thoroughly. Tamp the surface hard, being sure to remove any air pockets.
Continue adding layers of soil and cement, wetting each layer as you add it on and tamping each one hard before adding the next layer. When your form is built up to ground level, fill it with water and let it soak in for about an hour or two, then dampen the surface again and cover with plastic sheeting to keep from drying out too fast. Add water as needed to maintain dampness for at least three days.
Soil-cement can be a good cheap substitute for asphalt. It is often used on low volume roads, sometimes with a chip seal finish. Soil-cement is not difficult to make, but it does require a little equipment.
The first step is to blend the sand and cement together before adding water. This reduces the amount of mixing needed to thoroughly blend the materials, and saves quite a bit of time. An easy way to do this is to use a small cement mixer, but you can also simply use a large tub to mix it by hand.
The second step is to add water, mix thoroughly until everything is wet, and then let the soil-cement mixture sit for about an hour in order for it to begin developing its strength. We usually add about 1 gallon of water per 94lb bag of cement.
After an hour or so, we then spray the entire surface with a fine mist of water from our garden hose. This additional water causes the soil-cement mixture to stiffen up even more so that we can lightly trowel the surface smooth before using the mechanical roller (shown below) to really compact it down hard.
This roller compaction creates more than just compaction of the soil-cement mixture;
Soil-cement is a mixture of Portland cement, natural soil, and water used to form a hard, semi-rigid paving surface. It is most often used in highways or as a sub-base for asphalt or other forms of paving, but it can also be used as a cheap stand-alone paving surface for driveways, sidewalks, patios, or garage floors.
Step 1 – Excavate the Area
Dig out the area you want to pave in soil cement to a depth of 6 inches and make sure the sides are straight with no curves. Use your tamping tool to compress the dirt into firm soil. The whole area needs to be level for the soil cement to work properly.

The best soils for making soil cement are clayey soils or gravelly soils with adequate fines content to enable compaction. The fines will help to fill all the voids between aggregate particles allowing for a strong dense mix. Soils that are sandy tend to have the largest particle size resulting in too many voids in the soil cement mix. Soils that are too fine and lacking in small particle sizes will result in weak mixes.
Soil cement is a type of soil that has been stabilized with a cement binder. This is a low-cost building material that can be used for pavements, roads, and other building structures. Soil cement is made by mixing soil with just enough cement to allow the mixture to be compacted.
Soil cement has been widely used in the United States since the 1930s. It was originally used for the construction of low-volume roads, runways, bridges, and dams. Today, it is also being used for the construction of residential streets, parking areas, and small driveways.
To make soil cement, you need a mixture of water, soil, and cement in appropriate ratios. Use a ratio of 2/5 water to 3/5 dry material to make the best soil cement. The amount of cement you will need depends on the quality of your clay-rich soil. The ratio should range from 1:8 to 1:15 parts cement to soil by weight. For one bag (94 lbs.) of portland cement, use between 8 and 14 gallons of water. You can mix it using a shovel or mechanical mixer.
