The best cement for footings is one that fills up cracks and gaps until the concrete dries, then it’s hard to tell it’s there. The second best cement for footings is able to do a good job at filling gaps by itself but isn’t as good at hiding the initial joint because its color has to be so light. A dark colored cement does a better job of covering small joints, but this comes at the expense of hiding cracks in the cement.
In terms of concrete, the best cement for footing is cement from a reputable manufacturer. You can buy it online or at building supply stores. Asphalt or bitumen will also work for footings as long as it’s mixed with enough water so that it can be adequately compacted.
Concrete is a fundamental building material. It’s used for foundations, floors, walls, and everything in between. But because concrete can be an all-encompassing material (and sometimes used in ways that don’t make sense), it’s important to know exactly what type of concrete you will need for each project.
Concrete or mortar?
When you’re laying your footings, you’ll have to decide whether to use concrete or mortar. Concrete is stronger than mortar but it takes longer to set, so if you don’t have time before the ground freezes in winter (or if there’s a frost coming on), then mortar might be better for more flexibility. Mortar also has the added benefit of being easier to work with since it’s more flexible and can be applied using a trowel or by hand.
On the other hand, concrete may be more durable than mortar in some cases especially when applied as a thick layer over an existing soil bed that has been compacted prior with heavy equipment such as backhoes or bulldozers. With this method, called paving over dirt (POD), it helps create a flat foundation without leaving any gaps between layers where moisture could collect which could potentially lead eventually cause damage down the line due moisture-related issues such as mold growths or wood rot.
Look for the right blend.
To determine which type of cement you should use, you first have to figure out what kind of foundation you are building. Concrete footings go under a post or pier, while piers are the supports for the posts themselves. For foundations that need to be built on soil, there are two main types: spread footings and helical piers.
For both types of foundations, it is important that the soil below the foundation is compacted enough so that it has adequate bearing capacity and will not shift over time. The general rule for determining whether or not this is possible is 1 cubic yard per inch of depth when calculating allowable loads applied directly onto each square foot in contact with soil (more on how this works later). If your soil does not meet this requirement then it will need additional reinforcement prior to pouring concrete into your footing forms.
Water content is the most important factor in determining whether or not you’re using a good mix.
Water makes up about 20% of concrete, and it determines how strong your footings will be.
Using too much water in your concrete mix can cause it to become weak and unstable, while using too little water will leave you with a hard and brittle surface that can crack easily. You want to find a happy medium between these two extremes: not so dry that everything turns into solid stone or so wet that all the cement dissolves into mud.
Use additives if you need to.
If you need to increase the strength of your concrete, consider using additives. These are materials that are mixed into the concrete before it sets and hardens. They may be included either in a batch mixer or after mixing has finished.
Some common types of additives include:
- Fly ash – this is familiar to many people as a component of coal-fired power plants, but it also makes for an excellent component when added to cement mixes. It helps produce stronger and more durable concrete than traditionally produced cement mixtures can offer, while reducing the amount of water that needs to be added during mixing (and thereby reducing cost). Fly ash also reduces energy consumption by replacing other additives with fly ash, since it has similar properties but doesn’t require heating up at high temperatures like those used for smelting metals before being added into mixtures such as Portland cement or slag cements.
Think about the weight of your structure.
The weight of your structure will also determine which type of cement you should use. If you are building a light-weight structure like a porch or small building, you can use an all-purpose cement. However, if you are building a large, heavy structure like a bridge or house foundation then it is best to use Portland cement instead.
If your structure needs to be moved after it has been built (such as when building houses), the lighter all-purpose cements are preferable because they won’t weigh down the building during transportation as much as heavier Portland cements would do.
finding the right cement for your project can make a huge difference.
You need to look for a cement that is suitable for your project. There are many factors which determine the suitability of a particular cement:
- Suitable for the job, climate and weight of structure
- Suitable for the water content of soil (not too high or low)
Once you have chosen your cement, you need to make sure that it’s not too heavy or weak.
