Concrete rheological properties need to be properly measured and predicted in order to characterize the workability of fresh concrete, including special concretes such as self-consolidating concrete (SCC). It was shown by a round-robin test held in 2000 [1,2] that different rheometer designs gave different values of viscosity for the same concrete. While empirical correlation between different ...

Nanotechnology is a favorite research area that revolutionized mechanical and chemical properties of materials. Recently, focusing on concrete as a porous material with micro-scale and nano-scale pores enthusiastic researchers developed their investigations to find out microstructure and mechanical properties of concrete. The aim of this paper is to investigate the effect of nano-silica as an a...


 The present study is an attempt to analyze the effect of micro rubber waste in self- consolidating concrete (SCC) and compare containing SCC with conventional additives such as SiO2 nano SiO2. use can be substantially important from environmental point view. Hence, specimens 1, 3 5% were made. Moreover, 4, 8 12% prepared their behaviour microstructure each other witness specimens. parame...
