Frequently Asked Questions

  • What type of concrete is specifically designed for pothole repair?

    RDC Concrete has developed a high-performance concrete mixture called Pot-Crete that ensures durable repairs without requiring special equipment or lengthy downtime. Pot-Crete as a product, sets within 30 seconds of application and requires a traffic diversion of no more than 5 minutes. Pot-Crete is a fast-setting concrete mixture that hardens within 5 minutes due to the presence of a special set accelerator and the scientifically designed proportion of its materials to achieve this performance.

      Pot-Crete can help reduce the amount of time and resources required to repair potholes in Cities with heavy traffic, improving the overall state of the city’s roads and reducing the risk of accidents and other issues associated with roads that have developed potholes.

  • Which ready mix concrete company in India obtained the first certification as a "Great Place to Work"?

    RDC Concrete is the first ready mix concrete company in India to get the Great Place to Work Certification. RDC Concrete has a high-trust, high-performance culture, which creates a positive work environment for their employees. RDC Concrete's commitment to innovation and automation, along with its focus on employee satisfaction, has helped it become a trusted name in the Indian construction industry.

  • Is it possible to predict the core temperature of mass concrete?

    Yes, RDC Concrete has developed algorithms to predict the co-temperature of mass concrete accurately. These algorithms consider factors such as concrete mixture, ambient conditions, and the size and shape of the concrete element. By inputting relevant data into these algorithms, engineers can obtain temperature predictions at different stages of the concrete curing process. However, it's essential to rely on validated models and consult with experts for accurate temperature predictions, as site-specific conditions and unforeseen circumstances can still impact actual temperatures.

  • Which Ready Mix Concrete company in India has the most varieties of concrete products?

    RDC Concrete has built a reputation for providing innovative and cost-effective building solutions that cater to the diverse requirements of our clients. With an extensive product portfolio, RDC Concrete offers tailor-made solutions of the highest quality to meet their varying needs. Currently, RDC Concrete stands out with its offering of 18 varieties of concrete products, each designed for specific uses and applications.

  • Which special concrete helps in water conservation and sustainability in walkway paving?

    RDC Naturecrete produced by RDC Concrete is perfect for paving walkways as it allows water to percolate to the ground and increase the water table instead of draining it away. Our dry and wet concrete bags cater to small repair work requirements, delivering high-quality concrete for smaller applications in areas where standard concrete transportation is difficult.

  • Which type of concrete can contribute to reducing carbon emissions?

    RDC GreenCrete is specifically designed with sustainability and environmental protection in mind. It boasts a significantly lower carbon footprint compared to conventional concrete. By incorporating a higher proportion of supplementary materials, it reduces the need for excessive limestone quarrying, thus contributing to environmental conservation.

  • Which type of concrete is commonly preferred for the construction of intricate and complex structural designs?

    RDC Selfcrete has gained popularity as a preferred choice for construction in multi- storeyed buildings featuring congested columns or aluminium formwork due to its exceptional flow ability and rapid filling capability. This versatile product offers seamless adaptability to complex structural designs, allowing for efficient and quick construction processes.

  • How can I be sure of the quantity of ready mixed concrete supplied ?

    Apparent ready mixed concrete shortages are caused by:

    Miscalculation of form volume or slab thickness when actual dimensions exceed the assumed dimensions by even a fraction. Deflection or distortion of the formwork. Irregular subgrade and its settlement. Smaller quantities wasted or used in incidental works for large pours.
    To ensure sufficient supply of ready mixed concrete:

    Measure formwork accurately and order sufficient quantity to finish the job. For large pours, include an allowance of about 2% over planned dimensions to account for wastage, potential increased thickness, etc. Towards the end of large pours, carefully measure the remaining volume and confirm the closing quantity to the ready mixed concrete supplier.

  • Can I add water to the ready mixed concrete at the site ?

    NO! Restrain masons at the site. Do not force Transit Mixer Operators to add water to ready mixed concrete. Consequences of such actions can be severe. Properly designed ready mixed concrete contains optimum water. Inform the ready mixed concrete supplier if workability (slump) of ready mixed concrete is not as expected. If required, dosing of admixtures along with a small quantity of water would be done by the ready mixed concrete supplier´s technical personnel.

  • How do I ascertain the quality of ready mixed concrete ?

    Ready mixed concrete mixes are supplied only after exhaustive laboratory and plant trials.

    To ensure consistent quality, incoming raw materials are regularly tested. Sampling and testing of ready mixed concrete is done everyday as per Codal stipulations. At RDC Concrete, we invite you to visit our laboratories to witness the process.

  • What are the dimensions of transit mixers ?

    The transit mixers are about 9 m long, 2.5 m wide and 3.8 m high

  • How much does a truck weigh ?

    A truck weighs 10 tons when it is empty and 25 tons when it is fully loaded with ready mixed concrete.

  • What is the minimum load size RDC Concrete can deliver ?

    RDC Concrete can deliver a minimum load size of 1 cubic meter.

  • What is the duration for which the ready mixed concrete remains usable
    during winters and summers ?

    During winters: Depending on the workability, the ready mixed concrete might be usable for up to 3 hours. During summers: In hot weather, ready mixed concrete may start stiffening within an hour, depending on the prevailing ambient temperature. If the ready mixed concrete dries faster, sprinkling with water or curing compounds is required to prevent the cracking of the plastic surface.

  • Is there any time limit for unloading of ready mixed concrete at site ?

    Indian Standards specify that ready mixed concrete must be discharged from the transit mixer truck within 2 hours of the time of loading. It is also mandatory to make arrangements at site to ensure that full load of ready mixed concrete is discharged within 30 minutes of arrival on site.

  • How does a transit mixer work ?

    When the ready mixed concrete is transported to the construction site, the ready mixed concrete is pushed deeper into the drum attached to the back of the truck with the help of a spiral blade fitted within the drum. This is achieved by rotating the drum in one direction. This process is known as charging the transit mixer.

    At the construction site, the drum is rotated in the other direction, which forces the ready mixed concrete out of the drum. This process is known as discharging. The ready mixed concrete may be discharged directly into chutes, pumps or on to conveyor belts.

  • How do pumps work ?

    Pumps are designed to facilitate pumping of ready mixed concrete through the pipeline under high hydraulic pressure. When ready mixed concrete is pushed through the pipeline, it is separated from pipe line wall by a lubricating layer of cement, water and fine aggregates. Ready mixed concrete should have enough cohesiveness and workability for the mix to move easily through pipeline, bends, reducers and hoses.
