Nano-materials on the strength of ultra-high performance concrete

Abstract

Traditional concrete can no longer meet people's needs for construction quality in terms of quality. This study mainly discusses the effect of nanomaterials on the strength of ultra-high performance concrete. In response to people's concerns, this study improves the performance of concrete filled with nanomaterials from two indicators: the bending strength of concrete after being doped with nanomaterials and the tensile strength of concrete. When studying the flexural strength of concrete filled with nanomaterials, take nanomaterials with masses of 10 g, 20 g, 30, 40 g, 50 g, and 60 g, and fill them with high-performance concrete with a mass of 500 g. In the experiment, the bending strength of the concrete pier was measured. The experimentally measured that when the mass of the nanomaterial is 50 g, the concrete pier has the best bending strength coefficient, and the bending rate is 90%. When studying the tensile strength of concrete filled with nano-materials, nano-materials with diameters of 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, and 6 mm were used to fill high-performance concrete with a mass of 500 g. In the experiment, the tensile strength of the concrete pier was measured. The experimentally measured that when the diameter of the nanomaterial is 1 mm, the tensile strength coefficient of the concrete pier is 88%. During the experiment, the amount of nanomaterials and the individual particle diameter of nanomaterials were controlled. The experimental results show that when the amount of nanomaterials is 50 g and the diameter is 1 mm, the ultra-high performance concrete has the best strength. Nano-materials are of great significance in the use of concrete.
