Study provides preliminary results of experimental study of tile grout material behavior. Experiments were performed with the use of microCT, three point bending test and methods for chemical analysis. It was proven that material behave very elastic and the suitability of the combination of used methods.

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. The main characteristics that distinguish UHPC from conventional reinforced concrete are the improved compressive strength, the tensile strength, the addition of steel fibres, and the resistance to corrosion and degradation. The mechanical properties of UHPC allow for smaller, thinner, lighter sections to be designed while strength is maintained or improved. The use of UHPC has been limited to a few structure applications due to the high cost of the materials and the lack of established design guidelines. 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. Reinforced concrete is being used extensively in the construction industry all over the world. The use of Ultra high strength concrete has increased due to its obvious advantages like increased modulus of elasticity, chemical resistance, freeze thaw resistance, lower creep shrinkage and lower permeability.
