The Advantages of Pre-Mix Concrete: A blog about pre mixed concrete as compared to onsite concrete.
Pre-mixed concrete is a specialised material in which the cement aggregate and other ingredients are weigh batched at a plant in accordance with a set recipe. It then travels to the site in a ready mix truck, or can be delivered by agitator trucks or volumetric mobile mixers.
On-site concrete is produced by adding cement to a mixture of aggregate and water (typically called “aggregate”) and mixing it at the building site, either with water or an admixture, or both. The process requires two people – one to operate the cement mixer and the other to shovel the aggregate from below into the mixer drum. The mix is allowed to settle before being poured into formwork. This type of mixing is time consuming, labour intensive and produces inconsistent results especially when done manually.
Here are some reasons why you should consider using pre-mix in your next project:
The Advantages of Pre-Mix Concrete
In ready mix concrete, the workability and strength of the concrete can be optimized by the ready mix company to suit your exact needs. You also have access to a wider range of concrete mixes, which are often not available in premixed bags at the local hardware store.
Pre mixed concrete is a great money saver as well. There is no waste, since you only pay for what you use. Onsite mixing can result in unused concrete being dumped or left behind, which is a waste of money and materials.
It is also more convenient to use pre mixed concrete in many applications, such as filling in large holes and small trenches. There are many different mixes available for specific applications, so you can be sure you will get the best results for your project. You may find that some mixes are very hard to source from your local hardware store or other suppliers, but all of these will be available from your ready mix supplier.
Pre-mixed concrete, is a specially engineered mixture of cement, aggregates, additives and water. It is delivered to the customer’s site fully mixed and ready to be used. The pre-mix concrete supplier will design a concrete mix for any application, whether it be a driveway, sidewalk, patio or any other pourable surface. They can also customize the mix with special additives such as accelerators or retarders to enhance the set time for placement.
The advantages of pre-mix concrete include: Consistency
* Consistency of quality
* Consistency of strength
* Consistency of appearance
Pre-mixed concrete is produced under factory like conditions where quality control and assurance measures are followed to produce a consistent product for each batch made. Concrete made onsite does not have such regulations. Each batch may be different in strength, quality and appearance due to variations in materials and ratios used, as well as the mixing techniques being used by the person making it. The product also requires more time to cure and harden correctly due to many factors that are out of your control.
Convenience
It is very convenient to have the material onsite ready to use without having to do any mixing yourself or making multiple trips back
Some Advantages of Pre-Mix Concrete
Pre-mix concrete is a versatile material that is an ideal choice for many construction projects. Whether you are pouring a sidewalk, laying foundation, or building a bridge, pre-mix concrete has the strength and ease of use that you need.
Concrete is a mixture of cement, water, and fine and coarse aggregate materials. There are three types of concrete: ready-mix, site-mixed and pre-mixed. Ready mix concrete is made at batching plants by mixing sand, gravel, Portland cement, water and other additives to create standardised mixtures. Site mixed concrete is made onsite by mixing the same ingredients in the proportions required for the specific application. Pre-mixed concrete is a specially formulated mixture of sand, gravel, Portland cement and water that comes in a bag or bucket. The bag can be conveniently stored until it’s needed. Pre-mixed concrete offers a number of advantages for contractors who need to do small jobs or repair work:
Pre-mix can be used for small jobs such as pouring footings for posts and decks or for repairing cracks in sidewalks or paving stones.
Using a pre-mix product reduces waste because it can be used as needed without any being
When you are looking for concrete to pour at a job site, there are several different options available to you, but the best option is to find pre-mix concrete. Pre-mix concrete is concrete that is mixed offsite and delivered to the job site in a ready-to-pour state.
The biggest advantage of pre-mix concrete over onsite mixed concrete is that it is nearly always cheaper. The amount of time you save by not having to mix the concrete onsite can also provide significant savings. Additionally, the quality of the concrete you receive will be much higher than if you were to mix your own since pre-mix providers can control all of the variables involved in mixing very closely.
Pre-mixed concrete is concrete that is batched or mixed at a central mixing plant, or in some cases delivered by a ready mix truck. Concrete mixed at the job site can be mixed in the truck’s mixing drum. For major construction jobs with concrete, this is the way to go. In fact, there are many reasons that you should only consider pre-mix concrete for your next project.
Pre-mix concrete is also referred to as ready mix concrete, and precast concrete. This type of concrete is usually produced in two methods:
1) Central Mixing Plants – The Central Mixing Plant is the traditional method of producing high quality pre-mix concrete. The plant itself has silos for storing different types of cement and aggregates (gravel, sand), and a large rotating drum for mixing all of them together into the product known as concrete.
2) Shrink Mixed Concrete – Shrink Mixed Concrete are special mixes where 80% of the aggregate is loaded into the truck first, then water and cement are added on top of it. This method results in a more homogenous mixture while allowing significantly less time for the entire process.
Sometimes it is necessary to add additional water to the ready
