Öz

Hazrr beton uretirru ..de yurtici ve yurtdisi pazarlarda yogun bir rekabet yasanmaktadir, Bu rekabette kuruluslar acismdan en onemli unsur, istenilen kalitede urun ve hizmeti ilk defasmda, zamanmda ve uygunluk kalitesinde teslim etmektir. Bu hedefi yerine getirebilmek icin; rnusteri ihtiyac ve beklentilerinin tam ve dogru olarak anlasilmasr, degerlendirilmesi, kurulusun ilgili fonksiyonlanna tam ve dogru olarak aktanlmasi, gerekli prosesler ve urunler icin cahsma kriterlerinin, metotIannm izlenmesi, urun ve hizmetin rnusteriye talep ettigi sekilde teslim edilmesi gerekir. "Kalite yonetim sistemi"nin esasi, bir maim veya hizmetin kalitesini olcmek ve rnusterilere "kalite guvencesi" vermektir. Bu ~all~mada, ham beton firmalanmn beton uretimlerinde kalite mUkemmeliyetine erismek icin malzeme temini ve beton uretimi esnasmda standartlann ongordugu kalite kontrol tekniklerinin TS EN 206-1 esaslan dahilinde ortaya konulmasi amaclanrmsnr. Mart 2004 tarihinde yururluge giren TS EN 206-1 standardi, TS 11222'nin yerine konrnustur ve insaat sektorunde henuz tam olarak bilinmemektedir.
