An investigation of the effects of chemical additives on the mortar phase

In concrete production the use of chemical and mineral contribution today is increasing rapidly in order to improve of strength, durability and viscosity properties. In this respect, ın this study it is investigated that the effect on strength and viscosity properties of used mineral and chmical additive in normal mortar. Thus, both the fresh and hardened properties of a worksheet that provides surveys were conducted. As aggregate 0-2 mm grain size of crushed sand, binding as CEM I 42.5 R cement used in the mortar mixture which three different chemical additives with fly ash mineral additive used. Water / Cement ratio of 0.5 and the amount of binder 500 kg / m3 in the mixture taken as constant, chemical contribution rate must be selected as %0.5 to %1 and %1.5, fly ash %10%-20% and %30 in rates has been substituted with cement. Viscosity of the the mortar was measured to determine the workability and consistencies characteristics. In General, the angular speed increases in viscosity of mortar is reduced and chemical additives mortars viscosity values higher than spending out of control mortars. By making 7 and 28 day compressive and bending tests for mechanical properties have been determined amount and type of additives on properties of the mortar. As a result, the mortar will be produced at different temperatures effect of super plasticizer additive for chemical additives both fluidity and strength according to the score from the other additives has been given to the most appropriate.
