The effect of contribution amount of normal and super plasticizers on newly preparep concrete and hardened concrete

Naphthalene sulfonate-based production of concrete used in the experimental study are widely used in this study classified as normal and super-plasticizer plasticizing additives with different chemical origins dosages or dosages recommended by manufacturers and a small amount more in the use of fresh and hardened concrete properties were investigated.For this purpose,naphthalene sulfonate-based normal plasticizer (NA) and modified polycarboxylate-based super-plasticizer (SA) contribution that obtained from Sika Firm, the four different size classes obtained by crushing stone and Denizli Inc. CEM 1 42.5 R cement were used. Used with different rates of contribution, 6 different varieties an done pure experiment and all those,in the alm of control, were done. In the experiments the rates of water and concrete was fixed and the difference of slump in cement,setting time, 2- 7, 28 day pressure results were examined.Used in the experimental study, naphthalene sulfonate-based normal plasticizer (NA) and modified polycarboxylate-based super-plasticizer (SA) used the contributions to changes in rates (%0.5,%1, %2) depending on the increase in fresh concrete slump, setting times elongation, resistance results in the optimum NA fall outside the boundary compared to the SA contribution to this increase in strength was observed with experiments. SA made contributions to %2 mixture separation experiments were observed.
