·One of the biggest problems responsible of the nonrenewable resources depletion and environmental issues is the construction industries which generates large amounts of mineral waste and harmful emitted gases Therefore these problems generated the necessity to search for alternative natural building materials based on renewable resources To study the
·The concrete of the deep mine shaft lining often produces a phenomenon similar to rock burst and basalt fiber has good crack resistance and is widely used in engineering construction From the perspective of concrete dynamics this paper conducts dynamic tests on ordinary concrete and basalt fiber reinforced concrete BFRC by using a Split Hopkinson Bar
·The use of basalt fibres to improve the hardened properties of concrete has increased in recent times The incorporation of these fibres into concrete results in a change in the hardened state of concrete However these fibres also influence the corresponding fresh properties of concrete specifically its workability Therefore it is critical to understand how the
·The low alkali resistance of basalt fiber limits its utilization in the strong alkaline environment such as cement and concrete as the reinforcing material Adding additive in the basalt rocks is the feasible method to enhance the alkali resistance However it is necessary to develop the efficient additive for basalt fiber
· With the living laboratory of Hubbard s Corner this field trial moves C Crete s basalt based C1157 concrete from a novel material to a pilot ready concrete for bigger projects said Donald Davies a longtime construction industry executive who is owner of the Seattle building and chair of Building Transparency a nonprofit
