The new generation of innovative projects has led to the use of greater amounts of reinforcement and the development of concrete with specific characteristics. It is necessary to use a material that ensures the uniformity of the cross section, as well as the adherence of the existing reinforcement, and due to this, the self-consolidating concrete becomes an technique alternative has great poten...

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...

semiconducting carbon nanofibers (cnf) are prepared from three different sources, i.e., acetylene, ethanol, and cotton by the chemical vapor deposition (cvd) process. these fibers are having rich elastic, engineering and conductivity properties. fresh self-compacting concrete (scc) flows into place and around obstructions under its own weight to fill the formwork completely and self-compact, wi...


 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...

The present study presents the effects of steel fibre aspect ratio on fresh and strength properties self-consolidating concrete (SCC). Steel having three different ratios (50, 65 80) with inclusion rate 0.2%, 0.4%, 0.6%, 0.8%, 1.0% was considered, SCC were investigated. Central composite design (CCD) RSM modeling considered to propose a regression model predict 28-day compressive fibre-reinforc...

In this paper, the effect of Polypropylene Fibers added to concrete on strength and thermal resistance of high strength concrete has been investigated. Therefore, five tests have been carried out to reach this goal which it includes; effect of weight percent of polypropylene fibers on mechanical properties of concrete, effect of fiber’s length on the strength of high strength concrete, effect o...
