We recently switched to Full Circle Sand for our ready mix operations. We were previously using a competitor’s unwashed screened concrete sand. We were having problems with the gradation and the silt content which was causing water demand to be unusually high and making our concrete perform with mixed results. We also had a number of supply issues previously as well. To date, Full Circle sand has worked very well for us and our mixes are performing as designed. I would recommend Full Circle to anyone as they have a quality product and good service.
