Use of recycled cement-based slurry water for making concrete

Abstract

abstract Due to limited water resources in Singapore and the escalating cost of potable water, industries are constantly encouraged and challenged not only to generate less wastewater, but to recycle, reuse or reclaim as much as possible. In the construction industry, a substantial amount of potable water is consumed annually. If the wastewater generated from some constructionrelated activities could be recycled and re-channelled as part of their consumption needs, a lot of savings would be realised and environmental sustainability practised. Unfortunately, due to a lack of performance-based industrial standards and emphasis, limited research data and inappropriate wastewater management practices, the use of recycled cement-based slurry water for making concrete has not been widespread.
