Using experimental planning to determine optimum mix propotion in order to solve togethe strength, permibility and thermal of roller compacted concrete

Abstract

      For Contiventional Vibrating Concrete (CVC), the process of concrete mix design is relatively simple, usually just 3-4 test mix with different cement rates, a cost only a few experimental several million VN dong. While designing mix Roller Compacted Concrete (RCC), the mix must determine how to simultaneously satisfy the technical requirements, including the most important for the RCC dam is required strengh, impermebility and heat in the RCC to control cracking. The consultants of Vietnam is often a lot of effort and funding to do experiments. (usually three to several hundred test mix, funding up to some three billion not including field experiments)

       This article, the authors was planning to use math to find the empirical distribution RCC initial level 2 label different concrete design, satisfying the above three technical requirements that have to do some experiments at least. Results can refer to the mix design process to reduce cost RCC
