Cam Elyaf Takviyeli Beton Üretim Sektöründe Risk Faktörlerinin Belirlenmesi ve Tahmini

Cam elyaf takviyeli betonunun inşaat endüstrisinde kullanımı estetik ve mekanik özelliklerine, hızlı ve güvenli üretimine bağlı olarak son on yılda popüler hale gelmektedir. Ancak diğer beton türleri ile karşılaştırıldığında daha karmaşık üretim süreçlerine sahiptir. Bundan dolayı detaylı üretimi için yüksek yatırımlar gerektirmektedir. Bu yüksek yatırımlar ise beraberinde çok çeşitli ve fazla risk faktörlerini getirmekte ve bunların yönetimi önemli hale gelmektedir. Bu çalışma, cam elyaf takviyeli beton sektöründe risk faktörlerinin güncel tanılarını tanımlamaktadır. Öngörülemeyen maliyet artışlarının ve bu tür beton üretimindeki gecikmelerin azaltılması hedeflenmektedir ve sektördeki işverenler, müteahhitler ve çevreler için değer katması düşünülmektedir.

Risk Factors Identification and Estimation for Glass Fiber Reinforced Concrete Production Sector

Glass fiber reinforced concrete (GRC) usage in construction industry has been becoming very popular due to its aesthetic, mechanical properties, fast and reliable production in the last decade. However, it has more complex manufacturing processes compared with the other types of concrete pouring systems. Hence, it needs to make higher investments for its more detailed production line. Higher investments carry along more and several types of risk factors, and it becomes necessary to manage them. This paper describes the actual identification of possible risk factors in glass fiber reinforced concrete production sector. And it aims to decrease the unforeseen increase in cost and delays in this branch of concrete production and it is considered to affiliate value for owners, contractors, and the environments in the sector.
