Waste wash water recycling in ready-mixed concrete

2001-3-1  The use of recycled waste wash water for the production of new concrete is dealt with by prEN 1008 standard : mixing water must meet severe requirements in composition and may be used only if concrete exhibits 7- and 28-day compressive strengths higher than 90% of the value exhibited by samples prepared with distilled water (in Table 1, the main requirements of pr EN1008 are shown in

Waste wash water recycling in ready-mixed concrete

Abstract. Production of large amounts of waste wash water coming from ready-mixed concrete plants leads to problems of environmental impact. National laws usually prohibit the disposal of such types of water, due to their extremely high pH value and suspended matter amount, and require the water to be treated prior to discharge. prEN 1008 provides ...

A study was conducted into the quality of recycled water at a ready-mix concrete plant to determine its suitability as mixing water for concrete. Concrete mixes made at a water/ cementitious ratio (w/cm) of 0,5, with or without 50% ground granulated blast-furnace slag, and mortars of 0,47 w/cm were prepared using municipal and recycled water. Recycled water was used to replace municipal water ...
