Benefits of Concrete Rmc Plant
Concrete is one of the most important components in the construction industry as its quality has a direct impact on the strength and durability of the structure. That is why ready-mix concrete plays an important role. Ready Mixed Concrete (RMC) is a tailor-made concrete, manufactured with standard composition and process, and then taken to the site in transit mixers. In manual concreting, managing labor and getting accurate concrete composition is a challenge. The advantages of using RMC are plenty as it helps improve efficiency and reduce wastage of resources.
Quality and Consistency
Assured quality as standardized methods are used at an RMC plant. Variables such as compressive strength, ingredients proportions, water-cement ratio, workability, and slump can be controlled and molded as per the requirement of the project. Strict quality control and process parameters have significantly increased the pace and the quality standards of today's structures, unlike the old times.
Efficiency and Speed
The traditional method of mixing concrete involved a lot of labor and a longer duration for the completion of projects. However, most of the process of making RMC is machine operated. With the advent of technology, the construction industry is moving towards reduced manual labor and higher efficiency. Currently, concreting can be done at a rate of 45-60 cubic meters in concrete plants compared to 15-20 cubic meters per hour previously done conventionally.
High Versatility
RMC has repeatedly proved to be a versatile construction material. It is manufactured to ensure functionality in a variety of demanding environments including indoor or outdoor, exposed or concealed, dry or wet locations. This tailor-made procedure is versatile as per the methods used by the site contractor, from its use to the method of placing it.
Reduced Wastage
Ready mix concrete makes use of bulk cement instead of bags of cement, thereby saving cement and reducing the dust caused. Cement saving also conserves energy and resources. Better handling and a proper mixing practice reduces the consumption of cement by 66%. Additionally, it reduces the storage space for the basic materials at the construction site. Hence, overall RMC assists in avoiding wastage of raw materials related to the construction process.
Environmental Friendly
In the modern world, conserving our environment has become a top priority. Creating the right concrete mix on-site involves emitting a lot of dust and risk. It not only reduces dust pollution caused by making the mixture on site but also prevents noise pollution. Petrol and diesel consumed is less thus noise and air pollution are reduced, hence minimal impact on environment.
Optimizes Lifestyle Cost
RMC is more durable and increases the service life and saves repair costs. With the guarantee of structural durability, and reliable strength, it is promising for all construction projects, housing as well as commercial.
Types of Concrete Rmc Plant
There are three types of ready mix concrete (RMC) depending upon the mixing of the various ingredients as given below:
It is also called dry-batched concrete because all the basic ingredients including water are charged directly into the truck mixer. The mixer drum is revolved fast at charging speed during the loading of the material and after that, it continues rotating at a normal agitating speed. In this type of ready mix concrete, also three types of variations are possible as given below:
Concrete mixed at the job site
While being transported towards the destination, the drum is revolved at a slow or agitating speed of 2 rpm, but after reaching the site just before discharging the material, it is revolved at a maximum speed of 12 to 15 rpm for nearly 70 to 100 revolution for ensuring homogeneous mixing.
Concrete mixed in transit
The drum speed is kept medium during the transit time, i.e. approximately 8 rpm for about 70 revolutions. After 70 revolutions, it is slowed down to an agitating speed of 2 rpm till discharging the concrete.
Concrete mixed in the yard
The drum is turned at a high speed of 12 to 15 rpm for about 50 revolutions in the yard itself. The concrete is then agitated slowly during transit time.
The concrete is partially mixed in the plant mixer and then balance mixing is done in the truck-mounted drum mixer during transit time. The amount of mixing in the transit mixer depends upon the extent of mixing done in the central mixing plant. Tests should be conducted to establish the requirement of mixing the drum mixer.
It is also called a central batching plant where the concrete is thoroughly mixed before loading into the truck mixer. Sometimes the plant is also referred to as wet-batch or pre-mix plants. While transporting the concrete, the truck mixer acts as agitator only. Sometimes, when the workability requirement is low or the lead is less, non-agitating units or dump trucks can also be used.
Residential Construction
In residential construction, ready mix concrete is commonly used for foundations, driveways, sidewalks, and patios. Its consistent quality and durability make it an excellent choice for these applications, ensuring the stability and longevity of homes and surrounding structures.
Commercial and Industrial Projects
For commercial and industrial projects, ready mix concrete is ideal for constructing office buildings, factories, warehouses, and shopping centers. Its ability to be customized for different structural requirements makes it suitable for a variety of load-bearing and non-load-bearing applications.
Infrastructure Development
Ready mix concrete plays a crucial role in infrastructure development, including roads, bridges, tunnels, and dams. Its high strength and durability ensure that these critical structures can withstand heavy usage and environmental stress over time.
Decorative Concrete
Beyond structural applications, ready mix concrete is also used for decorative purposes. It can be colored, stamped, or textured to create aesthetically pleasing surfaces for countertops, floors, and outdoor spaces. This versatility in design opens up numerous possibilities for creative architectural solutions.
Repair and Maintenance
Ready mix concrete is also valuable for repair and maintenance projects. Its ease of use and quick setting times make it ideal for patching cracks, resurfacing pavements, and reinforcing existing structures.
Working Principle of Concrete Rmc Plants
A concrete batching equipment follows a systematic pattern to process ready mix concrete. The process of this production starts with the weighing of different materials individually followed by the mixing of all components in a mixer. Below are the steps that a concrete batching plant uses:
Feeding of the aggregates: There are different bins provided that are for accommodation of aggregates of different sizes. Each bin will accommodate a size of aggregate for weighing. This helps in getting accurate results.
Aggregate weighing: The next important step is the weighing of aggregates. They are weighed one by one as they fall into a weighing conveyor. It is important to note that the weighing conveyor is suspended on load cells. This hanging design allows it to weigh the aggregates one by one effectively.
Aggregates transfer: As the aggregates are weighed, the next step is to transfer them to the mixing unit to mix with other substances. The aggregate weighing conveyor is equipped for this dual purpose. Immediately after the weighing is done, it will discharge the contents into the mixing unit.
Cement addition: Cement a binding material is an important part of a ready mix concrete. It is in powder form and stored into separate storage compartment far away from moisture. This compartment is called as a silo. The silo comes equipped with all safety accessories but without the provision for weighing. It has provision for transfer of cement using a screw type conveyor into the weighing unit.
Cement weighing: Cement weighing takes place in a separate chamber. It is called as a cement weigh hopper. This unit is suspended on load cells to get exact and accurate weight reading of cement. The cement weigh hopper is located near the mixing unit. It receives cement in powder form from the cement silo via a screw conveyor unit. The cement hopper will discharge the desired quantity of cement into the mixer after weighing it.
Water weighing: Similar to the principle of cement addition and weighing, a separate water weighing and discharge hopper is present near the cement weighing hopper. It receives water from the water tank. This hopper is also suspended and hanging on load cells, this enables it to weigh the accurate quantity of water prior to sending the water to the mixing unit.
Additive addition: Different additives can be added into the mix material as per the requirement. The plant is equipped with an additive bowl hanging on load cell. It follows the same principle of the cement and water weighing for additive addition into the mixing unit.
Mixing Unit: The twin shaft mixer is the heart of the concrete batching mixing plant. It may not participate in the weighing process of the materials, but it certainly does a very important job. It will accommodate all the materials for homogeneous mixing. This is an important process and the job of mixing unit cannot be considered inferior. It does a very important task of blending all the materials to form a perfect ready mix material. The paddle arms and tips equipped with the mixer play an important role in lifting the materials up so that a very superior quality of mixing and binding is achieved at the end of the mixing cycle.
Concrete doesn't actually ever stop curing as it gets harder and harder as time passes. However, for most ready mixed concrete combinations, it will have cured enough for nearly all purposes within 28 days. It's important to bear in mind however, that there are a number of different factors that can affect the time it takes for concrete to cure.
The reason why ready mix concrete gets stronger over time is because of a process called hydration. Hydration refers to the concrete mix retaining its moisture content which then facilitates a chemical rection between water molecules and cement. It is because of this clever chemical process that concrete's curing time can be affected by adverse weather conditions.
Weather conditions that affect concrete curing time:
Hot or dry weather – If the weather it too hot or dry, the concrete won't have enough available moisture to set properly which means it can be prone to cracking.
Cold and freezing conditions – If possible, avoid pouring concrete in the winter months as exposure to freezing temperatures can have a detrimental effect on the concrete's strength and, just like when exposed to hot temperatures, it can then be subject to cracks.
