On work where cement is being usedin quantities of half a car per day ormore, and where the mixing plant is lo-cated within reasonaI)le distance of thereceiving siding, the simplest method ofhandling bulk cement is to shovel it di-rectly from the car into wheelbarrows ofknovvn capacity and then through theprovision of proper runways wheel thecement directly to the charging hopperof the mixer.
