Suitability of Soil Washed Sand as Fine Aggregates to

This paper presents a study on suitability of replacing river sand with soil washed sand as fine aggregate in concrete. The study was based on a comparison of concrete performance produced from river sand and soil washed sand obtained from four locations in Sri Lanka; Homagama, Rathnapura, Anuradhapura and Bandarawela. Several standard tests including Sieve analysis, Slump test and Compressive

Elevated Sand Mounds for On-lot Wastewater Treatment

In a pressure dosed distribution system, the treatment tank effluent flows into a second smaller tank called a dose tank (Fig. 2), where the pump or siphon periodically distributes the effluent to the sand mound. The dose tank is an underground concrete or fiberglass chamber placed between the treatment tank and the effluent delivery line.

Effect of recycled aggregates and treated wastewater on

Jan 10,  · Combined effect of recycled aggregate and TWW on concrete. Two studies , investigated 13 different concrete mixes made with 100% construction wastes, 100% recycled water from the wet recycling process in ready-mix plants (meeting ASTM C94 and EN 1008 requirements), recycled water from membrane bioreactor technique and different proportions of GGBS. They concluded that concrete with 100% RA, 100% RW, 90% GGBS and 10% OPC shows the best performance but is still inferior to conventional concrete.
