Characteristics of treated effluents and their potential applications for producing concrete

摘要: Conservation and preservation of freshwater is increasingly becoming important as the global population grows. Presently, enormous volumes are used to mix concrete. This paper reports experimental findings regarding feasibility using treated effluents alternatives in mixing Samples were obtained from three effluent sources: heavy industry, a palm-oil mill domestic sewage. The discharge into public drain without danger human health natural environment. Chemical compositions physical properties investigated. Fifteen compositional each correlated with requirements set out by relevant standards. Concrete mixes prepared establish base for control performance. concrete samples evaluated regard setting time, workability, compressive strength permeability. results show that except some slight excesses total solids pH, satisfy recommended disposal requirements. Two performed well all In fact, one sample was comparatively better than normal concrete; 9.4% increase observed at end curing period. Indeed, addition environmental conservation, use could save large amount freshwater, especially arid zones.
