QPS

رقابة جودة

تسعى QPS إلى التطوير المستمر للتقنيات ، مع دمج أحدث التطورات التكنولوجية للتميز في توقعات عملائها. تلبي المواد الخام والمنتجات النهائية المعايير التي وضعتها QCS والمنظمات الحكومية المختلفة ومعايير BS. يتم إعداد جميع المواد وفقًا لمعايير ومواد QCS ، ويجب اختبارها واعتمادها قبل بدء عملية الإنتاج لضمان الامتثال للمتطلبات المحددة. يشرف موظفو مراقبة الجودة المؤهلين وذوي الخبرة على جميع مراحل الإنتاج ويمارسون يقظة صارمة بشأن جودة المواد الخام والمنتجات النهائية


تخضع هذه المنتجات النهائية لاختبارات جودة صارمة وفقًا للمعايير المحلية والدولية ذات الصلة. تتمثل سياسة QPS في السعي الجاد لتحقيق الرضا التام للعملاء من خلال توفير منتجات ذات جودة عالية وبأقل الأسعار الاقتصادية. أطلقت قطر لأحجار الرصف برنامجًا لضمان الجودة يتبع خطة مراقبة الجودة ، والذي تم اختباره ووجد أنه مفيد في الحفاظ على جودة الإنتاج مع تقليل الخسارة من خلال التلف والكسر..

PLANT AND MACHINERY

Our plants are regularly checked, maintained and logged by experienced engineers and technicians.

RAW MATERIALS

Aggregates and washed sand Routine checks are carried out by physical inspection as well as by sieve analysis of all procured aggregate and washed sand, to ensure consistency of quality grading.

CEMENT

Routine checks involve mandatory submission of test certificate by the supplier against each delivery, complying with BS-12-1996 and 4027-1996.

WATER

Potable water from the goverrunent water supply.

PIGMENTS

Routine checks involve the mandatory submission of a test certificates by the supplier against each delivery, complying with BS-1014-1975(1986).

STORAGE

All aggregate and sand are stored in separate bins, covered on the top from direct sunlight and rain by polythene mesh and concrete walls on the sides to prevent dust pollution. Interlock paving floor absorbs additional moisture. Cement is stored in elevated cement silos, pigments and additives in store and yard areas.

CALIBRATION

Weighing scales are regularly checked and periodical calibration is done by approved laboratories.

MIX DESIGN MONITORING

Routine combine grading checks by material engineers, ensure the water content of the raw materials to clear the designated weight, water-cement ratio etc.

FINISHED PRODUCTS

Comply with BS-6717, BS-7263, BS-6073 and local standards. Classification in the yard date-wise is done to ensure the system of dispatch to various project sites with identification tags.

Paving laying guideline

Sub base
All concrete pavement required a sub-layer. This usually a high quality granular all in aggregate material which is installed and compacted in layers to reach minimum 98%. This material will be in accordance with the National roads authority specification for road works. The uses of lower quality fill materials and recycled rubble fill should be avoided.
Road base

The material placed above the sub-base and beneath the laying course layer a road base layer will typically only be required in pavements that need to accommodate medium to heavy-duty commercial traffic or where the ground condition is poor and require improvement for the traffic loading. The road base layer will act as a stiffening layer in the pavement construction and a cement-bound granular material(CBM) or a bituminous macadam material. The conventional lean mix concrete or mass concrete is not suitable for use in block paven1ents.

Laying coarse

The layer of materials on which the block paving unites is bedded. Spread bedding sand evenly requirements of BS 7533-3.it is not permitted, to add cement or lime to the laying coarse material to act as a binder. For more heavy traffic sites the nominal depth of the laying coarse materials is reduced and allowable fine content is also reduced to minimize the potential for settlement and deterioration in use. Prior to screeding the bedding sand, the recommended base surface tolerance should be 10mm over 3m straight edges. The elevations and surface tolerance of the base determine the final surface elevations of concrete pavers. The paver’s installation contractor cannot correct deficiencies in the base surface with additional bedding sand or by other means. The surface elevations of the base should be checked and accepted by the general contractor or designed party, with written certification to the paving subcontractor, prior to placing bedding sand and concrete pavers. Joint (bond) lines shall not deviate more than 15mm over 15m from string lines. Fill gaps at the edges of the paved area with cut pavers or edge units. Cut pavers to be placed along the edge with a (double-blade pavers splitter or) masonry saw. Use a low-amplitude plate compactor with a rubber pad of 10mm thick capable of at least 22KN at a frequency of 75 to l00Hhz to vibrate the pavers into the sand. Remove any cracks or damaged pavers and replaced them with new units.

Filling the joints

After the initial vibration, spared sweep and compacted dry joint sand into joints continually until full. Run the compactor over the pavers from one side to the other side. If the sand is wet, spread it on the pavers, and let it dry before sweeping and vibrating it down into the joints.As the compactor moves over the pavement, brush more sand in to the joints, sweeping aside the excess sand. Repeat this procedure until the joints are full and sand can no longer be vibrated down into the joints. check the joints to be sure they are completely full after vibrating.

Safety

Good construction practices include employing good safety measures. Mark the work area with caution tape to alert others that work is being performed. Secure the area whenever you leave to prevent accidents. Insist that safety goggles be worn to protect eyes during saw cutting, chiselling and splitting pavers. Wearing an apron is good when using a wet-cut saw. Ear protection and a nosh-approved respirator also should be worn when operating the saw, compaction machinery or when working around other loud equipment. Fully-stocked first aid kit is the most important tool should keep in the work area and on hot summer days drinking plenty of water is important to avoid heat stress.
