A concrete mix has been designed as follows with a target characteristic compressive strength of 32 MPa. Constituent GP Cement Stone Sand Water Unit Content (kg/m³) 350 1250 860 165 Before batching, the Technical Specialist assessed the aggregate moisture condition of the stone at 1.0% and sand at 3.5%. The Technical Specialist also reviewed that the absorption capacity of the stone and sand are 0.8% and 1.4%, respectively. How should he adjust the water content to maintain the effective water/cement ratio of the mix?
