UHPC (ultra-high performance concrete) is a relatively new type of concrete that exhibits mechanical properties that are far superior to those of conventional concrete and high performance concrete. As the construction of super-high structures and long span structures increases all over the world, strength, and stiffness of structures are being improved by applying Ultra-high strength concrete. With such trends, demands to use 100Mpa or Ultrahigh strength concrete more than that are anticipated to spread out. The load strain relationship was evaluated based on strain measured by strain gauges on the concrete and rebar surfaces. Negative strain represents compressive strain and positive strain represent tensile strain. Positive to negative change represents the propagation of tensile cracks from the bottom face to the top face or by upward shift of neutral axis of the cross-section.

INTRODUCTION Generally, grades have been done as M-10 to M-20 ordinary concrete, M-25 to M-55 standard concrete, M-60 to M-80 High Performance concrete and now a new grade has also developed as Ultra High Performance Concrete. It is a highly ductile material formulated by combining Portland cement, silica fumes, quartz flour, fine silica sand, high water reducing agent, water, and steel or organic fibers. The main objective of the study is to analyze the comparison of deflection among different types of concretes such as M30, M60, M80, M100 (UHPC) which clearly shows the deflection is minimum only in case of ultra high performance concrete. METHODOLOGY The results obtained from the testing of various specimens of beams cast is included in this experimental program is presented and discussed. The results recorded for each test included the only measurement of deflection. The observed crack pattern, load propagation and mode of failure at ultimate load are reported. The testing of the beam specimens was grouped into three series. Series-1 consisted of total 10-beam:8-beams with dimension of150mm*200mm by 1600mmmade of a concrete grade of 2-beam of M-30, 2-beam of M-60, 2-beam of M-80 and 2-beams with dimension of 150mm*300mm by 2100mm1beam is made of M- 100 and 1-beam is made of M-80 and series-2 consisted of 4-beams with dimension of 150mm*200mm by2000mm2-beam is made of M-80. In the series of various beam specimen tested, the variable investigated cracks, cracking pattern and failure load represent the deflection. RESULTS AND DISCUSSIONS The test was performed on different grades M30, M60, M80, and M100 the observed values were taken for the formation of graphs depends upon their maximum load due to which deflection occurs.
