ANALYZING THE EFFECT OF MICRO RUBBER, MICRO SIO2, AND NANO SIO2 IN MICROCRACKS IN SELF-CONSOLIDATING CONCRETE (SEM OBSERVATION)


 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. parameters specimen age w/c ratio on was also studied. Thereafter, imaged using a scanning electron microscope (SEM) observe microcracks secondary beam (SE) used obtain images. results microstructural consideration different showed that 1% improve self-consolidating concrete, but strength quality decline increase its amount.
