Frequently Asked Questions

How do we arrive at the exact quantity of concrete required at our site?

Your architect/engineers need to work out the grade-wise concrete requirements and communicate the same to our plant. They are the right people and are in a better position to decide the quantities required. Concrete is generally specified in terms of the 28-day compressive strength and workability (usually slump) at placement point. These two are basic minimum requirements for us to design concrete mixes for you. We will ensure that concretes in accurate quantity and appropriate quality are delivered to your satisfaction.

What is minimum quantity of readymix concrete that can be order?

As we supply concrete by Transit Mixtures having capacity of 7 Cubic meter, minimum quantity of concrete to be ordered should not be less than 7 Cubic meter. If pumping of concrete is required, minimum ordered quantity should be 25 Cubic meter to avoide extra charges.

How is Concrete supplied at site?

Transportation of readymix concrete to site is done in a transit mixer which is capable of mixing the concrete en route .

How can we ensure that your transit mixer actually carries the correct quantity as claimed in your delivery docket?

We are a professionally managed ready-mixed concrete company, operating a fully automated and computerized batching system with the help of highly motivated personnel trained to control all process parameters carefully. Production data is automatically recorded and stored electronically in plant-based computers and can be retrieved and verified whenever you wish to do so.

Our plant has a weighbridge and all incoming materials are accurately weighed before being stored. Similarly, transit mixers carrying concrete are weighed from time to time to verify the accuracy of the material being supplied to various sites. You may visit our plant with prior appointment and verify the weights of the outgoing trucks on random basis.

Further, we measure the plastic density of fresh concrete from time to time and match the same with the theoretical density. In case of any noticeable discrepancy in the two values, immediate action is taken to rectify errors, if any. Last, but not the least, our Company has an unblemished reputation of adhering to ethical practices. Hence, you may safely trust us for your quantities.

What is the Maximum time allowed to unload concrete at site?

Maximum time allowed to unload concrete is half an hour after reaching at site. If the vehicle is detained for more than above specified time after reaching at site, retention Charges will be applied on your account for each hour of delay.

What buyer have to do at the time of placing concrete?

Our scope is restricted to supply readymix concrete as per your requirement , the responsibility remains with buyer for placing, finishing and curing of concrete. Buyer have to keep vibrator and other needed equipments ready before delivery.

It is buyers responsibility to provide good serviceable roads up to your site and to arrange for avoiding contact with upper electric, phone, cable lines etc.

What type of formwork required for readymix concrete?

It is preferable to use system formwork. Also the shuttering should be proper enough to withstand pumping pressure. Any loss of material, damages to any equipments, injury or loss to human life would be at buyers responsibility.

Upto what height and length, concrete can be pumped?

It depends on pump capacity. We can manage to pump concrete upto vertically 75 meters height and horizontally 100 meters length .

What is the laps time between mixing of concrete at plant and placing of concrete at site?

Generally 3 to 4 hours. However initial setting time can be delayed as per requirement by adding retarder / plasticisers dosage.

Use of chemical admixtures and compressive strength?

Chemical admixtures with retarder and plasticiser are used in concrete to increase workability and strength.

What is the ideal time for placing concrete?

We suggest you to prefer concreting at early morning or at evening to avoid shrinkage cracks to an extent. Because environmental conditions conductive to high evaporation rates such as low humidity, high temperature, direct sun light and drying winds on a concrete surface cause rapid surface drying resulting in cracking.

How strength of concrete can be determined?

Concrete cube moulds having size 15x15x15 cms are casted with sample concrete, cured in water tank for 7 and 28 days and crushed in compressive testing machine at 7 and 28 days to measure compressive strength of concrete.

What will happen if shape of aggregates used in concrete is not rounded/cubical?

If the shape of aggregates used in concrete is not rounded (or) cubical the interlocking of aggregate in concrete will not be proper and strength of concrete will decrease. If the aggregates are elongated (or) flaky the strength of concrete will be seriously affected and concrete will become porous..In hywel readymix concrete the 20 mm & 10 mm aggregates are properly checked for elongation or flakiness and their quantity is restricted within the limits of BIS standards, to get cohesive & durable concrete.

What is the importance of testing concrete?

The concrete has to be tested to know the strength of concrete at 28 days for each desired grade. Usually the concrete at site is not tested for its strength, workability, yield and other factors that ensure the performance of concrete over a period of time. However in hywel readymix concrete, the samples of concrete are tested for every batch to ensure consistent quality and supply of durable concrete.
