RCCMIX experienced logistics team works closely with you to ensure that the concrete of requisite quality is delivered on time and in the appropriate quantities.
RCCMIX considers technical capability as its core competency.
Engineers with relevant experience, exposure and educational qualifications are leading the technical department.
RCCMIX Technical Team is committed to R&D in concrete technology. Services of renowned concrete technologists are availed regularly for better knowledge creation.
RCCMIX plant comply with stringent requirements of the Quality Scheme
Having fully equipped laboratory plant to carry out various tests on concrete and on constituent raw materials.
Concrete mixes of various grades are designed in laboratory are complies with BIS standards.
The Quality assurance systems and procedures implemented by RCCMIX monitors every stage of the entire business process. Right from the processing of order, purchase/control of materials and concrete mix design to production, sales, delivery and control of concrete.
The quality system is periodically reviewed for improvement on a continual basis.
Compressive strength of concrete: Concrete samples will be done at the plant as well as at the site according to the frequency of sampling.
Durability: Scientifically designed mixes to ensure better durability of the structures.
Workability: Slump will maintain during the production and at the time of pour.
Test Certificates are issued regularly for testing of concrete.
Framework (Shuttering and Centering)
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:
It should be strong enough to withstand all types of dead and live loads.
It should be rigidly constructed and efficiently propped and braced both horizontally and vertically, so as to retain its shape.
The joints in the formwork should be tight against leakage of cement grout.
Construction of formwork should permit removal of various parts in desired sequences without damage to the concrete.
The material of the formwork should be cheap, easily available and should be suitable for reuse.
The formwork should be set accurately to the desired line and levels should have plane surface.
;It should be as light as possible.
The material of the formwork should not warp or get distorted when exposed to the elements.
It should rest on firm base.
Have sufficient manpower to manage the concrete when it is being poured and for the finishing process
If possible avoid placing concrete at noon or during the afternoon
Consult with the structural engineer or designer to maximize and implement an effective plan to properly space control joints.When placing concrete in hot weather, control joints should be spaced at smaller intervals than cold weather concrete joints.
Use sunshades or windbreaks to reduce possible harsh conditions.
Plan to have indoor slabs poured after all walls and roofs are built.
Reduce the mixing time once water has been added to the mix.
Do not add water to the pre-mixed concrete unless it is part of the design.
When placing concrete for a slab, first dampen the sub-grade.
Curing of concrete is defined as providing adequate moisture, temperature, and time to allow the concrete to achieve the desired properties for its intended use.
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. For slabs, ponding is the best method of curing.
For effective curing of concrete, do ensure that
Continuous and adequate supply of water is available at the site throughout the curing period.
The exposed concrete surfaces are kept in the wet or damp condition for at least 10 days from the date of placing concrete. Curing for 14 days would be ideal.
In hot weather, curing by sprinkling of water is started within 4 to 5 hours of batching of concrete and continued till bunds are prepared and ponding is done.
In some cases, when the temperature is above 30°C and strong winds are blowing, concrete surfaces may dry very fast inducing plastic shrinkage cracks as early as within 30 minutes of concrete placing. In such a situation, trowel the cracked concrete surface while it is still plastic to erase the cracks and then ensure that the concrete surface is continuously kept wet.
Curing water and material used for bunds are free of substances which may stain or discolor concrete.
Preferably cement mortar is used to prepare of bunds instead of earth.
Bunds for ponding of water are maintained throughout the curing period.
The height of bunds is sufficient for the ponding water to cover entire area uniformly including corners and edges. To avoid dry spots, water should be ponded for at least 20 mm above the highest point of concrete surface.
