PRODUCT DESCRIPTION BFRP MiniBars™ Patent Pending PRODUCT DATA SHEET ReforceTech Basalt Fiber Reinforced Polymer BFRP MiniBars™ are an engineered macro fiber reinforcement designed to increase the structural strength of concrete by uniform distribution of MiniBars throughout the concrete matrix. Concrete reinforced with RFT MiniBars™ demonstrates Det Norske Veritas (DNV) testing has demonstrated that the unique ReforceTech process delivers a strong bond excellent flexural toughness and energy absorption between the concrete and the BFRP bars. Further testing capability after cracking when tested according to ASTM with the University of Akron demonstrated results of C78 and C1399 and EN16451. Flexural Tensile Strength (ASTM C78) enabling the increase from 4.5 MPa (653 psi) for normal concrete up to Testing demonstrates that MiniBars™ satisfy the relevant 17 MPA (2465 psi) depending on volume fraction of residual strength requirements based on ASTM C1609 MiniBars™. Testing Average Residual Strength (ASTM tests (as specified in ACI 318-­‐08) using MiniBars™ as shear C1399) has developed ARS from zero in normal concrete to over 17 MPa (2465 psi). reinforcement in reinforced concrete slabs and beams. From volcanic basalt stone thin basalt fibers are combined ReforceTech BFRP MiniBars™ are engineered to deliver in ReforceTech’s patented process to create unique macro high flexural toughness and energy absorption in concrete fiber called MiniBars™. The MiniBars™ are engineered to in conjunction with proven alkali resistance and create the optimal mechanical bond and cut to the engineered bond strength. prescribed length 20 to 60 mm (0.79” to 2.36”) to achieve the desired concrete performance.
FROM BASALT TO STRUCTURAL PRE-­‐REINFORCED CONCRETE Basalt stone Melted Basalt Fiber MiniBars TM Pre-­‐Reinforced Concrete UNIQUE ENABLING FEATURES TO REDUCE PROJECT COSTS •

Corrosion Free allows thinner lighter structures Zero Conductivity, eliminates galvanic corrosion Improved Flexural and Average Residual Strength of Concrete allowing design freedom, elimination or reduction of normal reinforcement Compatible Specific Gravity – 1.9 g/cm3 means uniform distribution, MiniBars™ do not settle or float and are easily mixed. Suitable for site work, precast or dry concrete. •

No MiniBars protrude from Concrete; no MiniBars™ are visible on the surface. Improved freeze thaw resistance Savings of labor costs and faster construction Improved abrasion resistance Improves safety on site by eliminating handling of traditional steel reinforcement Excellent Bond related to engineered helix, rough fiber surface, bond length and diameter.
