This paper studies on the influence of impermeability in basalt fiber of C50 concrete, and the result was compared with the same dosage of polypropylene fiber. Experimental test show that after incorporating basalt fiber and polypropylene fiber concrete impermeability resistance were significantly improved, the impermeability of polypropylene fiber is superior to basalt fiber.

Rain Erosion

Concrete structure will be corroded under acid rain scouring and soaking for a long time, which has a great influence on its durability life. In order to further study the damage characteristics of fiber reinforced concrete under acid rain erosion, the formation mechanism of acid rain and its influence on the corrosion and deterioration of concrete and fiber materials were analyzed in this paper. Taking basalt fiber concrete as an example, the characteristics such as porosity, compressive strength and mechanical indexes were studied and analyzed. Moreover, the reasons for the optimal fiber content was briefly analyzed. The results show that the inner structure of basalt concrete mixed with 0.1% fiber was the most stable and the corrosion resistance was the most satisfying.This conclusion has certain reference significance for the corrosion damage research of fiber reinforced concrete.

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.
