Production of high strength and colored concrete using textile waste reactive dyestuffs as superplasticizers
Abstract Herein, we are reporting the effect of reactive dyestuffs, currently widely used in textile industry, on the hydration of Portland cement and their usability as water-reducing additives. For this purpose, solutions containing various ratios (0,005- 0,016 g/100 ml tap water) dyestuffs as superplasticizers were used as mixing water for cements. The effects of these dyes on the hydration of Portland cement were determined by physical tests and DSC-TG-DTG, FT-IR and X-ray diffraction techniques. It was found that the dyestuff added to the cement reduced the cement water/cement ratio (2–7%) and increased the compressive strength (8–13%), depending on the molecular size and structure, and it was also determined that it had no negative effect on cement hydration.

Highlights Waste dyestuff mixing waters can be used instead of superplasticizers in cements. It has been found that reactive dyes do not have a negative effect on cement properties. Textile wastewater can be used as alternative chemical additive in the cement industry. It will contribute to the solution of an important problem on health and the environment.
