Sustainable development goal 6: clean water and sanitation—could be a big challenge for water-stressed India. Use of non-potable water for concrete production can contribute largely towards this goal. Scattered experimental studies on concrete mixed with non-potable water having different pH, were ...

The testing results show that the pH value for given fly ash in distilled water is alkaline, the influence of water-fly ash ratio is little, but the kind of fly ash is more. When the fly ash is added into Ca(OH)2 solution, the initial pH value increases, and is above 12.0 ...
alkalinity of pore solution in the carbonation process and formation process of hydroxyl ions ionized in pore solution is discussed, and an improved concrete carbonation theoretical model is recommended. The proposed model is related to the critical pH value for steelbar depassivation of concrete pore...
