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.
Thermal and Mechanical Properties of Basalt Fibre Reinforced Concrete
— In this study, the thermal and mechanical properties of basalt fibre reinforced concrete were investigated. The volume fractions of basalt fibre of (0.1, 0.2, 0.3, and 0.5% by total mix volume) were used. Properties such as heat transfer, compressive and splitting tensile strengths were examined. Results indicated that the strength increases with increase the fibre content till 0.3% then there is a slight reduction when 0.5% fibre used. Lower amount of heat conducted through the thickness of concrete specimens than the conventional concrete was also recorded.
Capturing Crime in the Antipodes: Colonist Cultural Representation of Indigeneity
This chapter adopts a Southern criminological lens, which allows the authors to explore how colonialism has been constructed and depicted in museums within both regional and urban Australia. By studying spatial and historical silences in Australian museums, this chapter offers a consistent frame to chronologically chart Anglo-Australian depictions of Indigeneity, imperialism and violence wielded by the state. As this chapter will argue, museums can often reflect Westernized (white) conceptualizations about Indigeneity and the state violence involved in colonization, which actively re-enforces popular views and influences sociopolitical visions of identity, the state and justice.
