Introduction of Ready Mixed Concrete
Concrete is one of the most crucial building materials used in construction projects around the world. It provides a strong and durable foundation for structures and has been evolving over the years to meet the growing demands of the industry. One such evolution is the introduction of ready mixed concrete, a mixture of cement, water, and aggregates that is prepared off-site and delivered to the construction site in a ready-to-use form. This innovative approach has transformed the way in which concrete is produced and utilized, offering numerous benefits and advantages to the construction process. In this article, we will explore the concept of ready mixed concrete, its history, production, and its impact on the construction industry.
Types of Ready Mixed Concrete
Ready mixed concrete is a versatile material used in construction projects around the world. It is a mixture of cement, water, and aggregates (sand, gravel, or crushed stone) that is delivered to the job site in a ready-to-use form. This efficient and convenient form of concrete has become the preferred choice for many construction projects, ranging from small residential buildings to large infrastructure projects.
There are several types of ready mixed concrete that are used in different applications. These types are distinguished by their different compositions, strengths, and uses. Let’s take a closer look at the different types of ready mixed concrete.
1. Transit Mixed Concrete
Transit mixed concrete is the most commonly used type of ready mixed concrete. It is delivered to the job site in a concrete mixer truck and is mixed during transportation. This type of concrete is usually used in smaller projects such as sidewalks, driveways, and residential foundations.
2. Shrink-Mixed Concrete
In this type, concrete is partially mixed at the plant and then completed in a truck mixer on the way to the job site. This process allows for greater control over the final product and is used for projects where the delivery time is longer, or the location is far from the plant. Shrink-mixed concrete is commonly used in large construction projects, such as high-rise buildings and bridges.
3. Central Mixed Concrete
Central mixed concrete, also known as barrel-mixed concrete, is produced in a stationary batch plant. All the ingredients are thoroughly mixed in the plant and then transported to the job site in a truck mixer. This type of concrete is usually used in large, complex projects, such as highways, airports, and dams, where consistent and high-quality concrete is required.
4. High-Early Strength Concrete
This type of concrete is designed to gain strength quickly after being placed. It is achieved by using a higher cement content and special admixtures that accelerate the curing process. High-early strength concrete is commonly used in emergency repair work, where a quick return to service is necessary, or in cold weather conditions when regular concrete may take too long to gain strength.
5. Self-Consolidating Concrete
Self-consolidating concrete (SCC) is a highly fluid concrete that can flow and fill even the most congested areas without the need for mechanical vibration. It is made with a higher paste content and reduced coarse aggregate to achieve its unique properties. SCC is commonly used in heavily reinforced structures, architectural concrete, and in areas where formwork cannot be accessed easily.
6. Lightweight Concrete
This type of concrete is made using lightweight aggregates, such as expanded clay, shale, or slate, to reduce its weight while maintaining its strength. It is commonly used where weight is a concern, such as in high-rise buildings, bridge decks, and precast concrete elements.
7. Fiber-Reinforced Concrete
Fiber-reinforced concrete is made by adding fibers (steel, synthetic, or natural) to the concrete mix. These fibers increase the concrete’s strength, durability, and flexibility, making it suitable for high-traffic areas, industrial floors, and earthquake-resistant structures.
In conclusion, the type of ready mixed concrete used in a project depends on various factors, such as the project’s size, complexity, and required strength. Each type of concrete has its unique properties and uses, and it is essential to consult with a professional to determine the most suitable type of concrete for your project.
Advantages of Ready Mixed Concrete
Ready Mixed Concrete (RMC) is a type of concrete that is manufactured and delivered to the construction site in a plastic or unhardened state. It is a popular choice for construction projects due to its numerous advantages. As a civil engineer, I have had the opportunity to work with RMC on various projects and have experienced firsthand its benefits. In this essay, I will discuss some of the advantages of Ready Mixed Concrete.
1. Consistency and Quality: One of the main advantages of RMC is its consistency in quality. It is produced in a controlled environment using precise measurements and techniques, resulting in a uniform and high-quality product. This means that the strength and durability of RMC are of a higher standard compared to site-mixed concrete. This consistency also helps in achieving the desired strength and properties of concrete, which is crucial for the structural stability of any building.
2. Time-Saving: In the construction industry, time is money. With RMC, the concrete is ready to use as soon as it arrives at the site. This eliminates the need for on-site mixing, which can be time-consuming, especially for large projects. Moreover, the use of RMC also reduces the time required for curing, resulting in faster completion of construction projects.
3. Cost-Effective: Although the initial cost of RMC may be slightly higher compared to site-mixed concrete, it proves to be cost-effective in the long run. Using RMC reduces construction time, labor costs, and material waste, resulting in overall cost savings for the project. Additionally, the consistent quality of RMC reduces the need for expensive repairs and replacements, further reducing project costs.
4. Improved Site Safety: On-site mixing of concrete can be hazardous and can result in accidents, especially for inexperienced workers. RMC eliminates this risk as the concrete is delivered to the site in a ready-to-use state. This reduces the likelihood of accidents and injuries on the construction site, making it a safer work environment.
5. Environmental Benefits: RMC is an eco-friendly option compared to site-mixed concrete. The production of RMC at a central plant reduces the carbon footprint as it reduces the number of vehicles needed to transport materials to the site. It also helps to reduce noise pollution, air pollution, and waste generation on the site.
6. Flexibility in Design: RMC allows for a wide variety of designs and finishes due to its consistent quality and availability in different grades and mix proportions. This gives architects and engineers the flexibility to design and construct unique and complex structures with ease.
7. Reduced Maintenance: As mentioned earlier, RMC has a consistent quality and strength, ensuring long-term durability. This means that the building or structure constructed using RMC requires less maintenance over time compared to site-mixed concrete. This results in cost savings for the building owner and also reduces the inconvenience of frequent repairs and maintenance work.
In conclusion, Ready Mixed Concrete offers numerous advantages over traditional site-mixed concrete. Its consistency, quality, time-saving, cost-saving, safety, environmental benefits, and design flexibility make it a popular choice for construction projects. As a civil engineer, I highly recommend the use of RMC for any construction project to achieve a high-quality and durable structure within a shorter time frame and at a reduced cost.
