Quality Control

Quality Control Laboratories

 

Batch plants equipped with the state of art laboratories to control and monitor the quality of raw materials as well as the design of concrete mixtures in order to ensure that the concrete is exceeding the required specifications.

 

 

 

FILOMIX READYMIX is committed to providing the highest quality levels to our customers, Our batch plants are well equipped with Quality Control laboratories that have the latest testing equipment to conduct quality tests on fresh and Hardened concrete as well as acceptance and rejection tests on raw materials, including cement and aggregates with highest accuracy and consistency standards. The accurate control in the production process is consistent with the quality control management system that we have in our batch plants. As the overall quality control system in batch plants aims to identify and correct most of the errors before the delivery of concrete to sites. FILOMIX READYMIX is committed to performing periodic calibration of equipment and scales used in the production of concrete and tests are conducted according to the special calibration schedules in order to verify the stability of quality in batch plants and tests are in conformity with the standard specifications. FILOMIX READYMIX quality assurance program is applied to verify that the concrete produced is in conformity with the highest quality standards and there is a consistency of performance of the concrete mix, Aside from the date of production or delivery site. FILOMIX READYMIX produces and sells the concrete in accordance with the quality standards specification and technical requirements of clients. Our goal is to build strong and extensive relationships with our customers and to maximize the benefit and profitability for all parties in the long term. Therefore, the Company is:

 

  • Selecting carefully the raw materials through conducting the necessary tests for each concrete component to confirm the quality and conformity with the standard specifications and its suitability for use in concrete mixtures in order to achieve the highest levels of quality and durability of the design mix and to meet the requirements of the customer.

 

  • The concrete mix is designed accurately in accordance with the required specifications by the client or consultant and concrete test are performed to achieve the optimal performance.

 

  • The company is committed to using the control program in the central mixers by the computer to achieve the highest levels of accuracy in the concrete mix through controlling the content of aggregates, cement, additives, and time of mixing.

 

Quality control laboratories include the equipment hereunder:

  • Automatic Compression Testing Machine 2000 or 3000 KN ELE. 
  • Standard ASTM sieves.
  • Drying Oven.
  • Air Entrained pressure meter.
  • Precision balances.
  • Cube molds 15*15*15 cm for the concrete test.
  • Cube molds 5*5*5 cm for cement test.
  • Slump cone set.
  • Curing tanks.
  • Flakiness and Elongation index Gauge.
  • Unit weight measure 10 lit.
  • Digital Thermometers.
  • Lab Mixers.

Raw materials used in concrete production:

  • FILOMIX READYMIX chooses the best raw material used in the concrete production delivered from accredited local authorities and international companies.
  •  The company's quality assurance team ensures the source of material such as quarries, crushers, factories, and ensure to get the manufacturing test certificates.
  • According to the quality control plan, the Quality Assurance team perform a visual examination and to revise the received invoices, as well as samples and for each raw material received in batch plants.
  •  The usual tests are conducted on all materials that are received.
  • Aggregates are stored in appropriate containers, according to their sizes.
  • Cement is stored in waterproof silos, according to the cement type.
  • Additives are stored in waterproof containers according to their type. And these containers are supplied by the additives supplier in accordance with the standard specifications of these materials.
  •  Water tanks are completely isolated and made of iron provided with the cooling unit to keep the water temperature at the desired degree of mixing.
