| Sumario: | Compressive strength and flexural properties of the cement mortar, and Water-cement ratio in the mix design, the ratio of aggregates to cement and cement strength class are the main parameters determining the properties of cement mortar. The optimization of the concrete mix design technology plays an important role, recently statistical method that has been considered by researchers to optimize the response surface methodology (RSM). In this article to achieve an optimal mix of factors affecting the quality of the mortar properties of this method has been used. In this regard, 12 mix design has been evaluated. The samples in the vicinity of solutions containing 0, 5 and 10% sodium chloride are located. The result of the paper represents the possibility of using this method is the continuous improvement of concrete mix design. Which can serve as a useful tool in concrete production units and production units used prefabricated concrete. Search optimization results with response surface method for compressive strength and flexural show that optimal mix design to achieve maximum compressive and flexural strength a mix design which the percentage of chlorine used at a rate of 5%, cement strength class is highest (42.5 MPa) and water to cement ratio is the minimum amount. |
