This research presents a novel approach based on the combination of nanotechnology and Roman technology by investigating how adding nanoCa(OH)(2) and nanoSiO(2) modify the performance of air lime mortars containing Roman ceramics. Microstructural, physico-mechanical properties were periodically controlled until 120 days of curing. XRD and TGA analyses showed that adding nanoSiO(2) either alone or with nanoCa(OH)(2) were more beneficial to improve the pozzolanic activity in the mortars. The less stable hydrated phases generated led to microcracks which eventually impaired compressive strength but enhanced deformability capacity. These results provide insight into the development of highly compatible mortars for cultural heritage.

Parameter optimization on compressive strength of steel fiber reinforced high strength concrete Ayan, E.; Saatcioglu, Oe.; Turanlı, Lutfullah (Elsevier BV, 2011-06-01) This paper illustrates parameter optimization of compressive strength of steel fiber reinforced high strength concrete (SFRHSC) by statistical design and analysis of experiments. Among several factors affecting the compressive strength, five parameters that maximize all of the responses have been chosen as the most important ones as age of testing, binder type, binder amount, curing type and steel fiber volume fraction. Taguchi analysis techniques have been used to evaluate L-27 (3(13)) Taguchi's orthogonal...
Effect of Presoaked Expanded Perlite Aggregate on the Dimensional Stability and Mechanical Properties of Engineered Cementitious Composites KESKİN, SÜLEYMAN BAHADIR; Sulaiman, Kamaran; Sahmaran, Mustafa; Yaman, İsmail Özgür (American Society of Civil Engineers (ASCE), 2013-06-01) This paper reports on an investigation of the use of expanded perlite aggregate as saturated lightweight aggregate (LWA) with respect to the mechanical and dimensional stability properties of engineered cemetitious composites (ECC). Expanded perlite aggregate was soaked in water for 24 h before its use in ECC, and replaced 10, 20, and 30% of the aggregate that was used in ECC production. The mixture proportion of a standard ECC mixture with properties that have been extensively reported in the literature is...
Closure to "Punching shear strengthening of reinforced concrete flat plates using carbon fiber reinforced polymers" by Baris Binici and Oguzhan Bayrak Binici, Barış (American Society of Civil Engineers (ASCE), 2006-03-01) This research presents a strengthening technique for increasing punching shear resistance in reinforced concrete flat plates using carbon fiber reinforced polymers (CFRPs). This strengthening method employs CFRP strips in the vertical direction as shear reinforcement around the concentrated load area in a specified pattern. Experimental load deflection curves, strain measurements, and failure modes are reported for four strengthened specimens and two reference specimens tested for the research reported here...
Mechanical behavior of CFRP confined low strength concretes subjected to simultaneous heating-cooling cycles and sustained loading Erdil, B.; Akyüz, Uğurhan; Yaman, İsmail Özgür (Springer Science and Business Media LLC, 2012-01-01) This study aims to present the mechanical behavior of carbon fiber reinforced polymers (CFRP) reinforced low strength cylindrical and prism concrete specimens under both heating-cooling cycles and sustained loading. Heating-cooling cycles range from -10 to 50A degrees C and the applied sustained load level is 40% of the ultimate strength of concrete. After 200 heating-cooling cycles and/or sustained load testing, specimens were tested to determine the mechanical behavior under uniaxial compression. The expe...
Long-term mechanical properties of cellulose fibre-reinforced cement mortar with diatomite Ince, Ceren; Derogar, Shahram; Ball, Richard James; Ekinci, Abdullah; YÜZER, Nabi (Thomas Telford Ltd., 2019-09-01) This paper presents a study investigating the long-term mechanical properties of cellulose fibre-reinforced cement mortars incorporating diatomite as a replacement material for quartz sand. Important properties including mass, compressive and flexural strength, sorptivity, water penetration depth and porosity have been rigorously investigated. Significant findings demonstrated that increasing the replacement level of diatomite resulted in a systematic decrease in the final mass of cellulose fibre-reinforced...
