Concrete composition having coffee carbonized ash |
| abstract |
The present invention is a concrete composition in which a mixture of cement and coffee ground ash, fine aggregate, coarse aggregate, and water are mixed, wherein the coffee ground ash is carbonized at a high temperature of 700 ° C. or higher, and as the carbonization temperature of the coffee ground ash increases, the mixture By presenting a concrete composition in which coffee grounds ash is mixed, characterized in that the mixing ratio of coffee grounds ash increases in It prevents the rust of the reinforcing bars to be placed and prevents the problem of reducing the strength of the concrete. |
