The ready mixed concrete industry is an important part of today's construction business environment. This industry provides the required quality of concrete used in construction works. The production of this concrete has many different operation parts and it is highly essential to obtain the required quality in these operations. The new trend; web-based management, has the characteristics of developing the business methods in any business environment as well as in ready mixed concrete industry. This paper presents a web-based system for the quality control of ready mixed concrete. The system is illustrated step by step and its benefits for this industry are examined.
Ready mixed concrete (RMC) is prepared generally in a computerized concrete batching plant and it is in plastic state when delivered to the construction site . RMC is one of the most popular building materials owing to its ability to customize its properties for different applications . RMC has several benefits when compared to concrete prepared by conventional methods in construction sites. First, it is subjected to a better quality control. Then, the materials used in the production of RMC are selected and stored properly in the batching plant, and ingredient materials for concrete production are weighed and mixed by automated devices. Moreover, the manufacture and transportation of this concrete are performed by skilled personnel. All of these factors results into better quality product of concrete in standard conditions . Concrete as a new material came first to building construction and later to other types of constructions . The production of RMC started at the beginning of 20th century in European countries and middle 1970s in Turkey. According to the European Ready Mixed Concrete Organization (ERMCO) records in 2001, View the MathML source350millionm3 of RMC was produced in 12 000 operating plants and the European RMC industry consumed 33–65% of the total cement sales . In Turkey, the number of batching plants increased during this period and the production reached to View the MathML source25millionm3 in 2003 . The quality control of RMC is getting more important due to the increase in the number of batching plants and amount of production of this concrete. Reducing the variations in production of RMC and producing uniform material for construction works are the aims of the quality control. This makes the quality control procedure such a system that considers all characteristics of materials, equipment and workmanship . Concrete quality is continuously improving by using today's modern technology . The quality of RMC can be controlled easily and more accurately by means of these new technologies. This paper presents a method using web-based technology that improves the quality control of RMC, reduces paper works in documentation and saves time and money for companies in RMC industry.

The construction industry is changing quickly by the rapid advances and developments in technology . Using web-based technology is a new trend in this industry. Companies have to adopt to these technological advances to get success in their businesses. Concrete is one of the most popular building materials for any construction work. It must meet the critical safety and durability requirements according to the relevant standards. Therefore, the quality of this material is considerably critical to provide a safety construction. In this study, a web-based system for the quality control of RMC has been presented. Benefits of this system are examined and illustrated according to the production and transportation stages of RMC. It has been revealed that the main advantages of this system are continuous control of the product, saving time and money, and improving the quality control. This new way of the quality control of RMC creates a better-qualified work and the opportunity for the companies to improve their business methods.
