Experimental Study on the Performance of the Basalt Fiber Concrete Resistance to Freezing and Thawing

Abstract:

The concrete composite material with basalt fiber as enhancing system in it has a lot of advantages ,including excellent mechanical properties , high temperature resistant, resistant to acid and alkali, low cost, environmental protection materials and resistance production process. It has been applied to the field of construction project. Damage of northern environment of freezing and thawing on the properties of the composite material has become a new hot issue. In order to study the characteristics of basalt fiber reinforced concrete as building composite materials in the process of freezing and thawing, this research uses the freeze-thaw cycle test to carry out the performance study on change of dynamic modulus of elasticity and quality loss of basalt fiber concrete. We use basalt fiber volume content of 0, 0.1%, 0.2% and 0.3% respectively of four groups of concrete specimens as the research object, to carry them on the freezing-thawing resisting performance test research. Research results show that the performance of dynamic modulus of elasticity and quality loss of basalt fiber concrete in freezing and thawing process is obviously better than the plain concrete. The dosage of 0.3% basalt fiber concrete freezing-thawing resisting performance is the best in the four groups of concrete samples.
