The dry pulverizing method mixed the soil and cement in dry conditions. An amount of cement was prepared before the mixing and then mixed with soil thoroughly in a batch mixer for about 10 minutes at a slow rate to produce a uniform mixture. The desired water was added gradually to the soil-cement mix to have a homogenous soil-cement slurry.Web
All codified methods for measuring the packing density of aggregate are carried out under dry condition. However, these dry packing methods do not account for the effect of water in the concrete mix.
