Our Services

our objective is to make your work productive, efficient & hassle free We have multiple services to cater your requirements, each being carried out by experienced professionals to ensure quality in works.

Concrete Production Service

Our ready mixed concrete production services include conventional concrete along with concrete with special properties. We do design mixes as per your requirements and specifications.

#

Concrete Pumping Service

In addition to concrete production and supply services, we also provide pumping services for ready mixed concrete. Whether a small house or a skyscraper, our pumping services make sure, that you get the concrete where required. Provided of course there is availability of proper access and safe working area.

#

Technical Service

We firmly believe that good and consistent work can only happen with a capable and knowledgeable workforce. We provide technical support on concrete, right from mix design to the placing, curing and testing of concrete to projects when requested. We provide trainings, guidance covering various aspects of concrete and QA/QC activities

#

Testing Service

We have installed a well equipped laboratory at our Plant. The lab is manned by qualified engineers and trained technicians. We can provide testing services to our customer for their raw Material and or concrete testing needs. We conduct tests on Cement, Concrete, Aggregates and Admixture.

Formwork

A properly constructed formwork is the cornerstone of a reliable concrete structure. Do have the formwork inspected and approved by a qualified structural designer before pouring the concrete. Here are a few guidelines that will help you build quality formworks:

For formwork of ground floor slabs, the props should rest on firm surface, preferably PCC. When the formwork is rested on earth, ensure that the ground is dry and well compacted. Use spreaders for props resting on ground.
Avoid the use of wooden props if possible; steel supports are preferred.
For slabs, ensure that props are vertical. Load carrying capacity reduces significantly when props are inclined.
To fix props, use bracings on both sides and runners at the center.
Seal any gaps in shutter joints to avoid leakage of cement slurry.
Before concrete is poured, ensure that interiors of the forms (shutters) are cleaned and shuttering oil (form release agent) is applied. Avoid the use of engine oil or other such lubricants as they may stain the concrete surface.
During concreting, forms, props, and all other supports must be continuously checked
After concreting, do consult your structural designer before removing the formwork. Listed in the table below are the recommended time limits as defined in IS 456:2000, ‘Plain & Reinforced Concrete – Code of Practice’

Reinforcement

Rough handling, shock loading and dropping of steel from a height should be avoided.
Avoid the use of wooden props if possible; steel supports are preferred.
Reinforcement should be free of rust, scales and coats of mud, oil or any other substances that may reduce or destroy the bond between steel and concrete.
Rebending and straightening of torsteel should preferably be avoided.
Do have the reinforcement checked by the structural designer after it is placed and secured.
The cover is the distance between the reinforcement and the concrete surface and is vital in ensuring the durability of the structure. Listed in the table below are the nominal minimum cover recommendations as defined in IS 456:2000, ‘Plain & Reinforced Concrete – Code of Practice’.
Cover blocks should be of concrete or mortar of same strength or of PVC.

Placing of Concrete

Improper placing of concrete could result in a defective structure that may require expensive repairs. While placing concrete, do ensure that:

The concrete is deposited in or very near to its final position.

The concrete is not placed in large heaps on the formwork. Moving heaped concrete manually or with a vibrator should also be avoided.

The concrete is poured vertically from a height of less than one meter; otherwise it may lead to segregation.

In mass concrete works, the concrete is placed in uniform layers; sloped layers may lead to segregation.

When thickness/depth of structure is more than 300 mm (1 foot), concrete is placed in two or more layers of equal thickness/depth. In general, the allowable thickness of each concrete layer ranges from 150 mm (6 inches) to 300 mm (1 foot).

Compaction of Concrete

Concrete, unless it is specifically designed for self-compaction, must be compacted. Compacting concrete removes the entrapped air and voids, and consequently increases the strength and durability of the concrete.

Curing of Concrete

Curing of concrete, which helps retain water in concrete that may have evaporated due to prevailing high ambient temperatures and/or windy conditions, is the last but significant step in concrete construction. Inadequate curing can result in concrete of poor strength and durability.

Curing is generally done by sprinkling or spraying of water, by ponding or immersion, and by covering exposed surfaces with wet jute or hessian cloth.

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.

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 Code stipulations. At RDC Concrete, we invite you to visit our laboratories to witness the process.

A truck weighs 11 tons when it is empty and 28 tons when it is fully loaded with ready mixed concrete.

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.

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

Uniqmix Concrete can deliver a minimum load size of 3 cubic meter.

1)During winters: Depending on the workability, the ready mixed concrete might be usable for up to 3 hours.

2)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.

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.

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.

From M10 to M100 grade concrete.
