Is cementitious material a dangerous good?
In most cases, cementitious material (materials that tends to stick to itself and form one solid mass) will not meet the definition of a Dangerous Good (Hazardous Material).

Always look beyond how it sticks together to consider how it compares to the actual definitions of a Dangerous Good in each of the nine hazard classes.
