Abstract:

In this research, the mechanical properties of carbon-containing concrete, including compressive strength, which have not been seen in any research so far have been investigated. So far, this additive has not been used for filling with internal materials. Increasing resistance by working with extra carbon dioxide is one of the most recent research topics. The ability to use carbon black to improve concrete properties, such as resistance, can be the cause of research. On the other hand, environmental degradation due to reduced cement consumption could provide a new era in the concrete industry. The present study examines the compressive strength of concrete with carbon black additive. For this purpose, five mixing designs have been used. A plan of control and four schemes containing carbon nanotube were considered in percentages of replacement of 12%, 8%, 4% and 2% by weight (relative to cement weight). Each of these five schemes for cement values was 0.40 and 0.45 and 0.5 was designed and built. The samples made in this research are examined for the compressive strength aspect, which is the compressive strength of the samples made at different ages of 7 and 28 days of concrete. The results of this study indicate that the use of carbon black for 4% by weight of cement leads to the highest compressive strength in the samples.
