Research Projects C-14 and C-15 were set up as purely laboratory studies with the same objective; that is, to study the affect upon the strength and durability of normal portland cement concrete by supplementing portions of standard concrete sand with variable amounts of "Fine" sand (sands passing Size No. 30 sieve). This investigation is not correlated with any Highway Department field projects. Project C-14 was begun June 16, 1944 and test completed April 20, 1945. Project C-15 was begun August 2, 1944 and tests were completed August 1, 1945.
