Compactness calculation formula: mass of soil * density of sand / what / data given by laboratory / (1 + 0.01%). What is the second one? Sand filling method

1 calculate the wet density first
Wet density = total mass taken out of test pit / mass of sand filled in pit * density of sand
2 dry density
Dry density = wet density / 1 + 0.01 * water content
3 compactness
K = dry density of pattern divided by standard density * 100%
4 evaluate and calculate the average and standard deviation

15. How to calculate the amount of sand in the mortar mix? Is it not the bulk density when it is dry? Why should the moisture content be added The mix proportion of cement lime mortar should meet the requirements of construction workability (consistency), ensure the design strength, save cement as much as possible and reduce the cost. The mix proportion of M7.5 grade cement lime mortar with consistency of 70-100 mm is used for masonry brick wall （1） Materials 1. Cement: 32.5mpa ordinary portland cement; 2. Lime paste: consistency 120mm; 3. Sand: medium sand, with a bulk density of 1450kg / m3 and a water content of 2%; 4. Construction level: General I don't understand the calculation of sand consumption The answer in the book is: according to the sand bulk density and moisture content, calculate the sand consumption QS QS =1450×(1+2%)=1479(kg/m3) But doesn't the amount of sand refer to the bulk density when it is dry? Why should 2% water be added? Isn't it the bulk density when the sand contains water? What's the matter
