Inside Aparna RMC and How Quality Control Ensures Perfection

 

 

In today’s construction where quality, on-time completion, and reliability are of utmost importance, ready-mix concrete has become an important construction material. However, the strength and consistency of ready-mix concrete are dependent on the quality control processes employed at each step of the RMC manufacturing process. 

Traditionally, concrete was prepared by mixing water and cement at the site. So, RMC is superior in quality when compared to the ones manufactured following manual mixing methods. Read the blog to learn the different quality control and testing processes we follow at Aparna RMC, one of the leading ready-mix suppliers. 

Challenges in RMC manufacturing

Ready-mix concrete helps ensure the timely delivery of concrete for construction processes. However, sufficient quality controls are essential to ensure that the final product meets the desired standards. 

Here are the common challenges in RMC manufacturing:

• Maintaining consistency and managing variations in raw-materials
• Inaccurate mix proportions across batches
• Inconsistency in water-cement ratio
• Equipment malfunctioning and breakdowns
• Improper storage of raw materials
• Human error in batching, equipment usage, etc. 
• Lack of temperature control
• Inadequate testing and lack of regular inspections

How does Aparna RMC test ready-mix concrete?

Aparna RMC has become an RMC plant manufacturer in India, majorly due to its commitment to quality. We have listed the different methods we follow to test the quality of RMC. They are generally brought under three phases

1. Raw material/ Ingredient testing

The quality of raw materials used in the manufacturing process determines the quality of the RMC. When they are sourced from external suppliers, the ingredients are tested following industry standards before reaching the manufacturing plants. 

At Aparna RMC, all the raw materials including cement, water, aggregates, and admixtures are tested for their quality before being fed into the process. For instance, the water purity is checked to prevent contamination. Dedicated stockpiling is followed to determine aggregates by grade and cement is stored in silos to prevent moisture from seeping in. 

2. Right batching and mixing

Aparna RMC uses advanced batching and mixing processes to ensure accuracy and consistency across the process. Automated batching plants help weigh ingredients based on the need and this avoids errors that may incur from manual operations. 

Advanced design software helps plant operators tune the mix proportions based on specific requirements and target strength. For instance, some projects may demand a target strength of M20 concrete while others may demand M15 or M40 grade concrete. So, based on the target strength, the software adjusts the mix ratio for concrete grades. 

3. Real-time production control

Our technicians and operators track all the important aspects including batch size, water-cement mix ratio for concrete grades, mixing time, etc. Ensuring that they align with the industry standards helps confirm that the ready-mix concrete output meets the desired quality standards.  

Post-manufacturing, the experienced team of technicians assesses the consistency and uniformity of the overall batch. This helps identify and correct issues relating to mixing and consistency. 

4. Lab tests for product quality

We employ different tests to ensure product quality. For instance, a slump test is used to determine the flowability and workability of the ready-mix concrete. Based on the grades required, the flowability is assessed. The slump test checks if the concrete is easy to pour while also preventing segregation or honeycombing issues. 

5. Density and temperature check

Temperature impacts the concrete setting time and they must be closely monitored. They are adjusted based on the specific project requirements. For instance, in hot weather, we use iced water or cool aggregates. Similarly, density is also checked for, after the RMC is manufactured.
