How to Calculate Quantities of Cement, Sand and Aggregate for Nominal Concrete Mix (1:2:4)? Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability, strength, setting time and durability.
Crushed Sand can be obtained from the Desert Biome, Wasteland Biome, and sometimes on the shores of any body of water. It can also be crafted in the Cement Mixer using Small Stones. Crushed Sand is used in the Forge to craft glass items such as the Glass Jar and Glass Pane.
Answer / nadim. the only advantage of using crusher dust in concrete is to reduce the volume of sand in the concrete mix whereas the disadvantage if we use complete dust in mix is it get mix with cement and form concrete balls which is not good in concrete mix design. advantages disadvantages of using crusher dust instead of sand in work..
