Concrete is a combination of aggregates, a binding agent, and water. The most common concrete combination is cement, water, and aggregates. This combination of concrete is typically used in the construction of slabs, beams, columns, and building foundations. The strength and durability of concrete make it a great material to use for any load-bearing structures.
Lime concrete was popular in construction before using cement as the binding agent became the trend. Lime concrete has global relevance as many historical buildings were built using lime concrete. Lime can be difficult to work with and can irritate human skin therefore it is suggested to be cautious if choosing to work with lime concrete.
Asphalt concrete is usually a combination of aggregates, water, and bitumen. Bitumen is a compound produced by distilling crude oil. The process of distilling crude oil separates the gasoline and diesel from the other components in crude oil. These remaining components are heavier than gasoline and diesel and this is what is used as bitumen. Asphalt concrete is used for road construction.
Concrete is a material usually used in construction but has slowly staked a claim in the world of crafts. From concrete pots to concrete ornaments to concrete art, it is easy to find a useful and exciting way to use concrete at work or at home. For at-home or professional use, concrete mixers are a great way to ensure successful concrete for your construction or craft projects.
Concrete can be mixed either by hand or in a concrete mixer. Mixing concrete by hand is time-consuming, labour intensive, and can result in cracks or faults in the concrete if mixed incorrectly. Failed concrete can also be a result of incorrect ratios of cement to water to aggregate.
Using concrete mixers to make your concrete is a way to ensure success. The power of the concrete mixers removes the effort and energy needed to make concrete. The constant rolling of the concrete mixers’ drum ensures an even and consistently mixed concrete. The reliability of concrete mixers takes the guesswork out of mixing concrete.
The constantly moving drum of concrete mixers also allows you ample time to use your concrete for your construction or project whilst it is still wet. Concrete mixers reduced the time pressure to get your work done quickly and helps avoids any possible mistakes caused by rushing.
Concrete mixers are here to make your life easier and ensure great concrete. If you are in the market for concrete mixers, B&S Commercial Power has a great variety for you to choose from.

Aggregate is a key player in the creation of concrete. Aggregate describes a combination of fragmented elements. Aggregate types vary according to the desired function and look of the concrete.
Aggregate is usually made from natural materials. These materials are often mined and then crushed to the desired shape and size. Aggregates can also be in the form of recycled material which can be more cost-effective.
Aggregates are beneficial in reducing the cost of your concrete. Aggregates act as a filler and therefore take up space in the concrete. This reduces the amount of cement, lime, or bitumen you will need in creating your concrete. Aggregates are generally cheaper than concrete binding agents and this makes your concrete more affordable.
The use of aggregates in concrete is important for the stability of the concrete. Aggregates provide the concrete with structure as the cement and water have particles to bind to. Stable concrete is sufficiently combined which ensures that there are no cracks or failures. Stable concrete is especially critical when being used for load-bearing in construction.
Aggregates also provide concrete with volume. The different types of aggregates you can add to your concrete will vary the volume of the concrete. The concrete volume needed is dependent on what the concrete is being used for.
Aggregates also increase the strength and durability of concrete which makes the concrete more resistant to erosion or damage. When concrete is being used in construction these qualities are critical to the building structure and safety of those who enter a building constructed with concrete.
Aggregates are categorised according to their different characteristics. The variety in aggregate size, shape, gradation and quality will impact the strength, durability, and possible uses for the concrete.
The aggregate size is one of the most important factors to consider when choosing an aggregate for your concrete. The size of your aggregate can range from sand particles to larger stones.
The aggregate size is determined through sieve analysis. This is a simple process of pouring aggregate through a series of sieves. The sieve mesh gets progressively tighter and therefore blocks certain sized aggregates at each point.
The shape of the aggregate affects the workability and strength of the concrete. Aggregates that are rough and angular can compact together. This increases the strength and workability of your concrete. Angular aggregates generally need more cement to keep them bound together.
Aggregates that are smooth and rounded tend to be less workable but are equally strong. The rounded aggregates generally do not require more cement, making this a possibly cheaper option.
If you are planning to have the aggregate in your concrete exposed, then the shape of the aggregate plays an important function in aesthetic appeal.
Gradation refers to the distribution or mixture of aggregates in the concrete. The correct distribution of the aggregates depends on what the concrete is being used for and the specific aggregate used in the concrete. The performance and quality of the concrete will be affected if not distributed correctly.
Well-graded Aggregate: There are minimum voids in the concrete mixture because the gaps caused by larger aggregates are filled by smaller aggregates.
Gap-graded Aggregate: There are even gaps in the concrete mixture caused using uniformly sized aggregate.
Continuously-graded Aggregate: The concrete mixture has an aggregate mixture that ranges in size. This will be defined as either fine or coarse depending on which aggregate type is higher in quantity.
The quality of your aggregate is important for your concrete. For aggregates to be of good quality for concrete they need to be hard, strong, and durable. Before you add your aggregates to your concrete, ensure that the aggregates are clean from clay, harmful chemicals, or other contaminants which can affect the water content in your concrete.
Aggregates you should avoid using in your concrete are aggregates that are soft, porous, susceptible to splitting, and have a low resistance to weathering.
Different Types of Aggregate:
Aggregates can be found naturally, manufactured, or recycled. Aggregate can be divided into fine aggregate and coarse aggregate groups.
Sand: Sand is the most used aggregate in concrete. Sand provides concrete with a finer texture which will give the concrete a smoother finish. Sand is also often used to ensure a well-graded aggregate. Sand is also a cheap aggregate to use and is highly adaptable. The types of sands used as aggregate are plaster sand, red building sand, washed river sand, and yellow building sand.
Crushed Stone: The texture of the stone is dependent on the size the stone has been crushed. Stone is a naturally abundant material perfectly suited to being used as an affordable aggregate. Commonly used stones are limestone, traprock, basalt, granite, marble, and quarts. These stones are all characteristically hard which makes them ideal to use as an aggregate.
Crushed Slag: Slag is a manufactured material and is a by-product of the steel-making process. The slag is skimmed off the top of smelting steel and then left to age and weather. Slag works well as a fine aggregate as it can be ground into evenly sized particles.
Generally, coarse aggregates are ten times larger than fine aggregates.
Gravel: Gravel consists of rock elements that are rounded and water-worn. Gravel will vary in size, shaping, and colouring which can make your concrete aesthetically interesting as well as stable.
Cement Clinker: Clinker is a lumped material that occurs during the production of cement. Clinker can be ground up into cement or used as a coarse aggregate.
Recycled Materials: Coarse aggregates which are made from recycled materials are often asphalt millings or broken concrete. This is a cost-effective aggregate especially if there are existing tar roads or buildings on a construction site which need to be demolished.
What Aggregate to Use in Concrete Mixers:
The aggregate you use is dependent on the requirements and aesthetic of your concrete. Any of the Baumax concrete mixers available at B&S Commercial Power are powerful enough to handle any chosen aggregate. The concrete mixers will easily combine your chosen aggregate, cement, and water to provide you with concrete ready to be used.
