densimeter वाक्य

Practices show that the compressive strength , the modulus of elasticity , the permeability coefficient and the compactness of concrete obtained respectively by the compaction method , the unconfined compression static compaction method , the sand trenching and filling method , and nuclear densimeters meet the requirement of design , and the mixing proportion of concrete of the side - wall is reasonable
Therefore , in addition to the measurement of dissolved solid concentrations obtained through online densimeter , transmittance measurements should be performed to provide online data about the second moment of csd ( crystal size distribution ) . in this thesis , a light sensitive resistor served as the light / electricity conversion component was used to measure the transmittance
