Abstract
The worldwide use and implementation of roller compacted concrete (RCC) is growing because of its good technical and economic advantages especially here in turkey. Chemical admixtures basically used for conventional concrete to increase its strength and produce a good quality concrete, and there are so many companies produce chemical admixtures for conventional concrete but only few companies produce chemical admixtures for roller compacted concrete (RCC). We were able to find the only company in turkey “Lyxor” to produce chemical admixtures for RCC; meanwhile this research aims to dictate the effectiveness of some chemical admixtures for roller compacted concrete (RCC) mixtures. We have conducted a test method to characterize some of the properties of RCC and these include the compressive strength and flexural strength with direct shear test. In this research we have used mainly 2 different types of chemical admixtures which include 3 types of superplasticizers which are Nanoment SP – Superplasticizers, Nanoment MR – Midrange Plasticizer, Nanoment HP – New Generation Superplasticizers, and the other type is Nano Aer – Air Entraining chemical admixture. We have conducted the test method by preparing 3 different RCC samples using each chemical admixture and tested them constantly within 3 and 28 days comparing them with 3 different None-admixed RCC samples which was prepared with the same procedure, and in the final we have prepared the test result table of each and every sample and the comparison chart as well. In the last part some recommendations and suggestions for the use of these chemical admixtures are mentioned.
