Microstructural study of blended concrete containing multiple admixtures

Microstructural study of blended concrete containing multiple admixtures The Fly Ash (FA) and Rice Husk Ash (RHA) are producing in huge quantity from industries and agriculture across the world. The proper disposal of such byproduct is major concern for environment. The FA and RHA have high specific surface area and silica content. The combined use of such material in concrete to form new triple blend concrete can be beneficial. This can achieve by using FA and three type of RHA as partial replacement of cement. In present research work, it was used by replacing 20, 30, and 40%. These new triple blend concrete were examined by compressive strength, microstructure by using Scanning Electron Microscope test (SEM), X-Ray Diffraction test (XRD), Fourier Transform Infrared test (FTIR) and durability by Ultrasonic Pulse Velocity (UPV) of concrete. According to the results, cement replacement at 20% was enhanced the durability, microstructure and strength of triple blend concrete. The paper concludes that the type-1 RHA and FA along with cement can produce sustainable results. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Building Pathology and Rehabilitation Springer Journals

Abstract

The Fly Ash (FA) and Rice Husk Ash (RHA) are producing in huge quantity from industries and agriculture across the world. The proper disposal of such byproduct is major concern for environment. The FA and RHA have high specific surface area and silica content. The combined use of such material in concrete to form new triple blend concrete can be beneficial. This can achieve by using FA and three type of RHA as partial replacement of cement. In present research work, it was used by replacing 20, 30, and 40%. These new triple blend concrete were examined by compressive strength, microstructure by using Scanning Electron Microscope test (SEM), X-Ray Diffraction test (XRD), Fourier Transform Infrared test (FTIR) and durability by Ultrasonic Pulse Velocity (UPV) of concrete. According to the results, cement replacement at 20% was enhanced the durability, microstructure and strength of triple blend concrete. The paper concludes that the type-1 RHA and FA along with cement can produce sustainable results.
