A concrete mixer is a tilting drum mixer that evenly blends cement, material like sand, and water to create concrete. Even in the most distant areas of the country, they are simple to use due to their tiny size and portability. Most cars’ trunks can accommodate our concrete mixers for sale in Kenya, while larger machines can be lifted into pickup trucks and hauled over greater distances.
The right combination and choice of ingredients are known as concrete mix formula. They are utilized to create concrete with specific properties in its hardened state. So as to achieve pre-defined durability, workability,capacity, as well as strength, ready-mixed concrete is made. But a suitable concrete mixture also depends on the following factors influencing the selection;
Durability
The durability of concrete is its capacity and toughness to survive hazardous and harmful environmental conditions. Any building, bridge, or construction project can benefit from the added strength that highly durable concrete can provide.
Builders or constructors should use the water-cement ratio to meet that specific need if the contractors do not require high-strength concrete but require a highly stable exposure condition. The ratio of water to cement must be precise. Durability will be worse if the w/c ratio is higher than the concrete.
Size and Structure
Controls over reinforcing steel spacing often define the maximum size and structure of the concrete. The concrete’s aggregate size is entirely at odds with the cement-to-water ratio’s proportional requirements.
It is because the concrete aggregate mixture’s size and pattern for the concrete mixture for sale in Nairobi are entirely proportionate for its workability. In general, the aggregate size determines the compressive strength of concrete; as the compressive strength increases, the aggregate size decreases to its Percentage.
Admixture
As was already mentioned, lowering the water-to-cement ratio below a certain point would make the mixture harder to work with. The use of water-reducing admixtures can provide a cement-rich mix and workable mix without excessive water, thereby achieving this property. Only by adding 45 to 55 percent water to the weight of cement can a good workable mix be produced.
As a result, even once hydration is complete, there will still be an excess of water. The extra water in the pores evaporates, leaving gaps behind. These voids are the leading cause of the failure fractures that develop and weaken the concrete.
Drum material
Concrete mixers often come with steel or plastic drums. Plastic barrels are lightweight and straightforward to clean. This enables your towing vehicle to tow a heavy load of concrete. Therefore, if you plan on buying concrete mixers that can withstand heavy-duty applications; you may find this type of drum more challenging.
Steel drums’ greater strength makes them the perfect choice.However, because of their vulnerability to corrosion, they require additional care. You may narrow down your options by ranking the concrete mixer possibilities according to how well they meet your needs in light of the factors discussed above.
Conclusion
It’s critical to comprehend the variables or determinants that immediately impact the choice of concrete mixer for sale design throughout construction. You should contact reputable suppliers if you require ready-mixed concrete for your building project and are considering ordering some. When selecting concrete mix designs for your project, they may ultimately help you.
