Question
what is mean by bulking of sand?
 Question Submitted By :: Civil-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Due to moisture in each particle of sand,sand gets a
coating of water due to surface tension which keeps the
particles apart.This causes an increment in volume of sand
kown as bulking.

Answer
# 2
Bulking of sand means increase in it's volume due to presence of surface moisture . The volume increases with increase in moisture content . The volume may increase up to 20 to 40% when moisture content is 5 to 10 %

Answer
# 4
When mixes are specified by volume, the sand is assumed to be dry. The volume of a given weight of sand, however, varies according to its moisture content. Equal weights of dry and inundated sand have practically the same volume but the same weight of sand in a damp condition can occupy a volume as much as 40% greater. This phenomenon is known as 'bulking'.

Answer
# 5
Sand when dampens occupies more space than when it was dry.
Increase 25% more sand and reduce 20% water otherwise it
will influence the water-cement ratio.

Answer
# 6
The increase in the volume of sand due to the presence of moisture is known as bulking of sand. This is due to the fact that moisture forms a film of water around the sand particles and this results in an increase in the volume of sand. The extent of bulking depends on the grading of sand.
