Son zamanlarda geliştirilen kompozit bir malzemeolan çimento bulamacı emdirilmiş lifli beton (SIFCON), inşaat mühendisliğialanında çok popüler malzemelerden biri olmuştur. Yüksek dayanımlı betonlardanen önemli farkı kırılma sırasında sünek davranış göstermesidir. Bu çalışmadaSIFCON'un rijit kaplama olarak kullanımı araştırılmıştır. Deneyler, L16ortogonal dizi tekniği kullanılarak her biri dört seviyeli dört faktör iletasarlanmıştır. Faktörler ve seviyeleri 40, 55, 65, 80 lifboyunun çapına oranı, 3%, 6%, 9%, 12% lif hacmi, 0,30, 0,35, 0,40, 0,45su/çimento oranı ve 0%, 5%, 10%, 15% silis dumanı oranıdır. Deney sonuçları Taguchiyöntemi ile varyans analizi (ANOVA) tekniği kullanılarak değerlendirilmiştir. ANOVA'yagöre, beton kaplamaların basınç ve eğilme mukavemetinde en önemli rolü lifboyunun çapına oranı (L/d) oynamıştır. Ayrıca basınç mukavemeti için optimum koşullar 55(L/d), % 3 lif oranı, 0.45 su / bağlayıcı oranı ve % 5 SD oranı, eğilmemukavemeti için 80 L/d, % 12 lif oranı, 0.45 su / bağlayıcı oranı ve % 5 SDoranı olarak bulunmuştur. Optimum koşullarda145.72 MPa ve 31.58 MPa'lık maksimum basınç ve eğilme dayanımı elde edilmiştir.

Slurry Infiltrated Fiber Reinforced Concrete (SIFCON) is one of the recently developed composite materialbecame a very popular material in civil engineering. The difference between high strength concrete (HSC) andSIFCON is the ductile behavior at failure. In this study, usage of SIFCON as a rigid pavement is investigated.The experiments were designed according to Taguchi method using orthogonal array technique in an L16 arraywith four factors with four levels each. The factors and their levels are 40, 55, 65, 80 fiber aspect ratio, 3%, 6%,9%, 12% fiber volume, 0,30, 0,35, 0,40, 0,45 water/cement ratio (w/c) ratios and 0%, 5%, 10%, 15% silica fumeratio. Analysis of variance technique (ANOVA) was used for analyzing the test results. According to theANOVA, the fiber aspect ratio (L/d) plays a significant role in compressive and flexural strength. Moreover,the optimum conditions were found to be 55 fiber aspect ratio, 3%fiber content, 0.45 w/c ratio and 5% SF ratiofor compressive strength and 80 fiber aspect ratio, 12%fiber content, 0.45 w/c ratio and 5% SF ratio for flexuralstrength. Maximum compressive and flexural strength of 145.72 and 31.58 MPa was obtained under theoptimum conditions respectively.
