Quality Plan

Receiving of Raw Materials

The quality control starts from the first production step, or the receiving of raw materials, SRM on site laboratory staff is responsible for receiving raw materials, and will insure that these materials comply with the requirements of SRM quality roles. The laboratory staff reports to the quality control engineer and follow the following procedure

Storage of Raw Materials

The raw materials are stored in proper areas, designed to protect the specific types in storage, such as

As the shipment of raw materials reaches SRM’s site it must stay outside the production yard, to be checked and inspected and the laboratory engineer is notified
Before receiving the raw materials, the responsible engineer will fill the receiving logs for the specified material, and will inspect it against shipping document..
Once the raw material is deemed in compliance with the requirement, the responsible engineer will approve the materials to be received. The receiving clerk will arrange the unloading of the truck in a way that doesn’t interrupt production while observing the safety procedures.
Should the materials show questionable quality characteristics, the engineer will recommend performing additional testing. Material under review will be stored separately until a final deposition by the engineer is delivered
Should the raw material fail to comply with the required quality, responsible engineer must reject the truck immediately without any tests

Aggregate & Sand :
Aggregate and sand are stored in big stores separated from each other with clear hard wall partitions, segregating each size and type
Cement :
Cement is stored in Silos of 150 tons capacity each painted in light color with cement filters & level indicators to protect the environment
Water :
Clean sweet water is stored in insulated tanks with capacity not less than 400,000 Lt.
Chemicals :
All admixtures and other types of chemicals are stored in insulated tanks, in a shaded area delivered using circulation pumps, preventing electro-deposit of chemical components

Materials Testing

All Materials received by SRM, will be subjected to quality control using both in-house laboratory testing as well as independent testing verifications

Batching Plant Operations

Batch plant operator is responsible for implementing the batch plant operational procedures that include proper line clearance between different design mixes, equipment and line cleaning, resetting of all weight systems to zero, checking hydraulic oils, electric breakers and the daily cleaning of the inside of the mixer.

The In-House Testing Program :
Periodic tests are performed ranging between daily to monthly, including the most common and essential tests, such as moisture content, sieve analysis, flakiness, elongation, slump, cubes, records of temperature and others as required.
The Independent Testing Program :
An independent and qualified laboratory will be used to perform all tests outside the capability of the in-house laboratory such as all chemical base testing. Periodic validation and calibration testing will also be performed by an outside and independent laboratory to conform continued validation of the tests and equipment.

Any observed deviations or possible breakdowns will be communicated to the production manager immediately for proper action. The plant operator is not allowed to produce any type of concrete unless he has an approved mix design from the quality control engineer, and after the mix design is installed in the computer system along with the particular contractor and project designation.
The batch plant weighing systems including (Aggregate, Sand, Cement, Water & Admixtures) must be calibrated every six months at a minimum, or after any related repairs that can possibly impair the proper functioning of the scales. The plant operator is also responsible for keeping a daily log of all production and its related project and customer designation in a log book or electronically. .
Once the raw material is deemed in compliance with the requirement, the responsible engineer will approve the materials to be received. The receiving clerk will arrange the unloading of the truck in a way that doesn’t interrupt production while observing the safety procedures.
Should the materials show questionable quality characteristics, the engineer will recommend performing additional testing. Material under review will be stored separately until a final deposition by the engineer is delivered
Should the raw material fail to comply with the required quality, responsible engineer must reject the truck immediately without any tests

Storage and Temperature Control

In order to alleviate the potential problem of the heat of the summer and its effect on the concrete temperature and its characteristics, the following preventative measures are taken:

Manufactured Concrete

All produced ready mix concrete will be checked and verified at the plant for compliance with customer requirements by the site technician. The following characteristics are checked at the plant prior to the concrete leaving the batch plant:

Sand is stored in a shaded area protected from the sides and top preventing direct solar heat
Cement silos are painted light colors to help decrease heat absorption.
The admixtures and chemicals are stored in tanks under a shaded area
When the temperature is extremely high and the concrete temperature requires temperature control, one chiller is available on site to cool off the water used to manufacture the concrete. Should the chiller be out of order or insufficient, ice flakes can be used to the same end

Initial slump
Initial concrete temperature.
Cube sample (as required for tests)
Each delivery of concrete to the customer site will be accompanied by a technician and the same characteristics are again checked at the point of delivery and a log is kept with the appropriate approving signatures.

Mix Design Control

A specific mix design is developed using the customer specifications.

Laboratory Procedures

The laboratory will produce the following:

The first step in preparing the mix design is studying and analyzing the general and special specification of the concrete required for the particular job, such as:
1. Source and characteristics of concrete raw components.
2. Characteristics of concrete (Strength, Slump…Etc).
3. Minimum and maximum cement content.
4. Range of the water cement ratio.
5. Any other special chemicals or/and requirements.
The second stage of preparing the mix design is to test the main characteristics of raw materials used in the “specified mix”, which must be in compliance with the limits of the international and/or project standards, including:
1. Sieve analysis of fine and coarse aggregates.
2. Specific gravity and water absorption.
3. Sulfate and chloride content.
4. Any other special tests if required.
Any other special tests if required.
The fourth stage is to perform a laboratory trial mix performed by the laboratory engineer. Samples will be tested as per the project specification, and data results recorded until the mix design is confirmed
The fifth stage is submitting the mix design to the consultant, to arrange a plant trial mix under his supervision
The sixth and final stage is to document the design mix and all the test results of its components and the final slump, compressive strength and any other characteristic required

Testing :
The testing program includes two main parts, the in house testing program and the independent testing program. All tests results are recorded in proper log books and date and periodic testing are observed consistently and records are kept safely.
Test Reports :
All tests performed in the company laboratory are written in summary format, in simple and clear bullet points easily accessible and legible by the technicians working in the laboratory.
Training:
Regular training programs for the company technicians are performed and a wide staff awareness program continuously expose all plant staff to the operational and test requirements of the concrete industry.
Calibration :
All the equipment and tools used in the laboratory for testing and measuring must be calibrated yearly or more frequently based on particular needs.
International Standards and Reference
All tests and methods are in compliance with the ASTM standards and a copy is always available at the laboratory for reference.

Concrete Delivery

The customer schedules are the main drivers in developing the order

Maintenance

SRM retains a full time mechanic and electrician on board to ensure:

The customer schedules are the main drivers in developing the order for deliveries. Delivery dispatching ensures the integrity of the timing between production and delivery of the concrete as this is a crucial and most important factor affecting the quality and compliance of the concrete.
Strict coordination with the customer site is done to ensure proper timing and receipt of the concrete at the customer site. All deliveries include the approval of the customer in the form of a signature on the delivery ticket.
The delivery ticket of the concrete contains all the detailed information regarding the content of the delivery and the component of the design mix and include the customer name, project name, concrete mix design, time of batching, truck driver identifications, time of discharging, plant and site checking, signature of the shipping clerk and quality inspector.

ARegular preventative monitoring
(Daily – Weekly – Monthly) Routine inspections and maintenance are performed for all equipment used in the production of ready mix concrete. In addition to the onsite mechanic, each equipment operator is made to care for his equipment and keep them clean and operational at all times and to report any hazard or breakdowns immediately for repairs:
1. Batching Plants.
2. Truck Mixers.
3. Concrete Pumps.
Breakdown Records
A full history of maintenance records is kept for all the equipment. Management continuously checks and analyzes the breakdown of each equipment, and plans for prevention first and quick response to breakdowns.
Standby Equipment
In most cases SRM tries to eliminate the single points of failure by making available duplication of equipment and tooling. The goal is to minimize any downtime arising from unexpected breakdowns. SRM maintains a substantial list of spare parts on the ready for repairs.
