Using the glass fiber to design the reinforced concrete with high split tensile strength to apply for the hydraulic construction

Abstract

     Using the Super-plasticizer and glass fiber to design the concrete of M20 ÷ M50 with high split tensile strength used for Hydraulic constructions. In the composition of the concrete design, to replace 10% Fly ash and 1.5% glass fibers with a length of more than 50 mm. The compressive strength increased from 15 to 36%, and split tensile strength of 15 to 30% increasing to compare with the control samples. Glass fiber reinforced concrete increased the split tensile strength, reduced the cracking of the concrete surface and concrete corrosion in the seawater. The glass fiber reinforced concrete suitable for irrigation works its requiring the high corrosion resistance.
