Study on the Fluidity and Strength Properties of High

Recently, it has been difficult to get natural sand for concrete due to an insufficient supply in Korea. Crushed sand was thought as a substitute and previous research has been focused on low fluidity and normal compressive strength (2430 MPa). Study on high performance concrete using crushed sand is hardly found in Korea. In this study it was investigated that the effect of the crushed

Performance of Glass Fiber Reinforced Concrete

investigated the performance of glass fiber reinforced concrete subjected to accelerated tests. The compressive, split tensile and flexural strength on M20, M30, M40 and M50 grades of concrete made of alkali resistant glass fiber was studied by Chandramouli [5]. For fibers with high aspect ratios, it was observed that the workability reduced
