The objective of this study is to compare the results of the compressive strength tests of a conventional concrete (cement-sand) f'c = 210kg/cm2 with different accelerator additives (SikaRapid ® - 1, SikaRapid ® - 3 PE, Chema PLUG and Chema 3) with W/C ratios of (0.58 and 0.60) cured for 1,3,7,14,21 and 28 days. The sample was made up of 384 concrete specimens. The results of this investigation showed the following with the additive (SikaRapid ® - 1) for 1 day it reached a resistance of 145kg/cm2 with an A/C of 0.58, but with an A/C ratio of 0.60, this being 135kg/cm2. The average compressive strength, with (SikaRapid ® - 3 PE) cured for 1 day, reached a resistance of 175kg/cm2 with a W/C ratio of 0.58, but with a W/C ratio of 0.60, this being 155kg/cm2. The average compressive strength, with (Chema PLUG) cured for 1 day, reached a resistance of 125kg/cm2 with a W/C ratio of 0.58, but with a W/C ratio of 0.60, this being 115kg/cm2. The average compressive strength, with (Chema 3) cured for 1 day, reached a resistance of 134kg/cm2 with a W/C ratio of 0.58, but with a W/C ratio of 0.60, this being 128kg/cm2. In this research, a resistance of 388kg/cm2 was achieved after 28 days by incorporating SikaRapid ® - 3 PE accelerator additive into the design, with a W/C ratio of 0.58. Finally, with the study carried out it can be concluded; that if the different types of additives that were seen in this investigation can be used for the production of concrete (cement-sand). Therefore, THERE IS A DIFFERENCE when using different types of accelerating additives in the mixture design which responds to our HI hypothesis.
