Mechanical Properties of Ultra High Performance Concrete Produced in the Gaza Strip
M. Arafa, S. Shihada and M. Karmout

Abstract:
The aim of this study is to produce Ultra High Performance Concrete (UHPC) in Gaza strip using materials available at the local markets. Hence, different trial mixes are prepared to achieve a compressive strength in excess of 120 MPa. This study also includes the use of mineral admixture (silica fume), basalt aggregate, quartz sand and special type of fine aggregate (crushed quartz) in preparing these mixes. Furthermore, compressive strength, tensile splitting strength and flexural strength of UHPC mixes are evaluated. The test results reveal that it is possible to produce UHPC in Gaza Strip, with compressive strength in excess of 120 MPa using available materials, if these are carefully selected and properly mixed in such away to optimize a grain size distribution. Based on the results of this study, the modulus of rupture is about 9.0% of the compressive strength, while the tensile splitting strength is about 6.0% of the compressive strength. Moreover, a number of equations are developed for the prediction of tensile splitting strength and flexural strength in terms of compressive strength. The output of these equations conforms with the relationships available in the literature especially at an age of 28 days.
