The manual furnishes a framework for management decisions regarding equipment, procedures or personnel, which may be necessary to create a quality manufacturing environment. Specifiers and users of precast concrete products are constantly seeking ways to identify high quality products.

The construction quality control system. Looking in more detail at the way the concrete quality control system works, it can be understood that the discrepancy of concretes makes it possible to minimise the consumption of cement, and ultimately allows the production of concrete to run more economically (Troxell, Davis & Kelly, 1965).

Evaluation of Statistical Quality Control of Concrete 1- Variation in strength of concrete The strength of concrete produced in sites is varied between mixes and even in in the same mix due to the following reasons: 2- Analysis of Strength Data 2.1 Definitions
