10mm aggregate concrete mix design vs 20mm in slovenia

When you use a smaller aggregate such as the 10mm as your nominal coarse aggregate size the specific surface area of the total volume of coarse aggregate is much higher than for the 20mm aggregate This means that your mix will require more cement more water and more fine aggregate in order to provide adequate paste coverage of the coarse aggregate and fill the high number of voids ...We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, briquette machine, mining, metallurgy and other related equipment. which can crush all kinds of metal and non-metallic ore, also can be dry grinding and wet grinding.If you are interested in our products or want to visit the nearby production site, you can click the button below to consult us.Welcome to our factory to test machine for free!
