Activities of your committee on Standard Concrete Building Units during 1927 show favorable progress on six major objectives. A series of preliminary tests was made for investigating the effects of various methods of tamping and feeding employed in the manufacture of dry tamped concrete masonry units. Acknowledgment is made to Messrs. Martin and George Hammerschmidt of the Elmhurst-Chicago Stone Company for furnishing the necessary materials and for the use of their plant in which the specimens were made.
