The collapse of civil engineering constructions has resulted in injuries, loss of lives, and investments which have been largely attributed to the quality of concrete ingredients used. The need to achieve certain properties suitable for a particular construction and the need to reduce cost in construction projects and achieve optimal results cannot be overemphasized. The study is based on the effect of packing density on the compressive strength of high-strength concrete with the application of metakaolin and conplast SP430 superplasticizer. To achieve this, five different combinations of coarse and fine aggregates for different packing densities were considered, with four different percentages of replacement of cement with Metakaolin (0%, 5%, 10%, and 15%). Therefore, based on the results obtained, it can be clearly stated that the packing density of concrete ingredients should be considered to improve the compressive strength and slump value of high-strength concrete.
