Experimental Study on Mechanical Properties of Basalt Fibre Reinforced Concrete
Concrete is very strong in compression but very weak in tension. However it is reported that tensile and bending strength of concrete is 10 to 15% of the compressive strength respectively. The addition of different types of fibres in concrete have significantly improves its compressive as well as tensile strength. Among the new advancement in field of FRC is the basalt fibre reinforced concrete. In the present study basalt chopped fibres were used in the concrete mixes and compressive and flexural strength of the specimens were tested. A total of 5 mixes were prepared by varying the percentages of basalt fibres on M 25 grade of concrete mix. Based on the laboratory results the compressive and flexural strength was reported to increase up to 46% and 74%. However the workability of fresh concrete mixes is not much affected by the addition of fibre content. The flexural strength of concrete is improved which shows the wide application of basalt fibres in concrete mixes for construction in various fields i.erailway, bridges, runway and tunnels.
An Investigation of Mechanical Properties of Basalt Fiber Reinforced Concrete
Concrete is the most widely used structural building material for the construction industry in today's world. The development of the mechanical properties of concrete materials is also very important in terms of project safety. Basalt fibers are materials that are the result of melting basalt in high temperatures. The purpose of the fibers in concrete is to provide ductility behavior property to the material by improving the tensile and bending strength as well as the compressive strength. In this study, ıt was investigated that the effect of basalt fiber contribution to concrete. Test specimens were produced by adding %1 ratio basalt fiber admixture to concrete specimens produced for this purpose, compressive strength, ultrasound pulse velocity and splitting tensile strength tests were carried out on 7 day and 28 day experimental samples. As a result, it was determined that concrete strengths of basalt fiber reinforced concrete increased the tensile strengths in the wind by %16.
Looking for regional words in late seventeenth-century England: Bishop White Kennett and his glossary to Parochial Antiquities (1695) 1
The analysis of regional dialects in the Early Modern period has commonly been disregarded in favour of an ample scholarly interest in the ‘authorised’ version of English which came to be eventually established as a standard. The history of regional ‘Englishes’ at this time still remains to a very great extent in oblivion, owing mainly to an apparent dearth of direct textual evidence which might provide trustworthy data. Research in this field has been for the most part focused on phonological, orthographical and morphological traits by virtue of the rather more abundant information that dialect testimonies yield about them. Regional lexical diversity has, on the contrary, deserved no special attention as uncertainty arises with regard to what was provincially restricted and what was not. This paper endeavours to offer additional data to the gloomy lexical setting of Early Modern regional English. It is our aim to give a descriptive account of the dialect words collated by Bishop White Kennett’s glossary to Parochial Antiquities (1695). This underutilised specimen does actually widen the information furnished by other well known canonical word-lists and provides concrete geographical data that might contribute to bridging the gaps still existing in the history of lexical provincialisms at the time.
