Flame Retardant Wood-Based Composite Modified by Chopped Basalt Fibers and Basalt Glass Powder

The chopped basalt fibers and basalt glass powder were individually used as the flame retardant additives, and fir sawdust and melamine modified urea-formaldehyde resin together made the composite matrices. The fireproof wood particle panel was obtained by hot compressing the mixture, which may improve the inherent flammable defect of ordinary fiberboard. The limiting oxygen index indicated that the best flame retardant property of the basalt fiber reinforced wood composite was reached when the weight fraction of the chopped basalt fiber was 10%. With and without the basalt fiber additives, the difference of flame retardant performances was 10%. The wood composite, modified by basalt glass powder alone, improved its limiting oxygen index up to 11.7% when the weight fraction of the additives was 15%.

Analysis on Mechanical Properties and Durability of the Chopped Basalt Fiber Reinforced Concrete

The current research situation of basalt fiber reinforced concrete was analyzed on the basis of the previous research results. When concrete is incorporated with basalt fiber, the compressive performance of concrete is instable, the tensile strength changes along with the fiber content, but the durability improves significantly , and the bending performance and impact resistance has more obvious improvement. According to the characteristics of chopped basalt fiber reinforced concrete, the prospect of the application of basalt fiber reinforced concrete is explored.
