cement to be used as Portland cement, ASTM designation C-9. During the period 1940-1952, consider-able research was done on various types of cement, methods of manufacture, and methods of curing cement-mortar to improve the quality of cement-mortar linings. As a result of this research, a revised edition of the 1939 standard was approved and ...
Cement may also be delivered in bottom-dump trailers that use gravity to move the cement. Other options include screw conveyors and bucket elevators. Cement is generally moved from the truck and into the storage silo using one or more of these transport systems.
Methods of Concrete Transportation Transportation of concrete is an important activity in the production of concrete. The time taken in transit should be a design parameter as it depends on the initial setting time as well as the requirement of workability at the destination. The method of transportation adopted at site should be decided in […]
