3. The maximum size of the aggregate, when not deter mined by other factors, should be determined 36 as to obtain the lowest possible cost of the concrete, taking into account the cost of the aggregate and that of the quantity of cement necessary for the type of aggregate used.

Excerpt from The Strength of Fine-Aggregate Concrete

I. Introduction

During the meeting of the Texas Road Builders' Association in Austin, February 18 to 20, 1920, the general discussion of concrete construction developed the facts that in certain sections of Texas the available local concrete aggregate is rather fine; that coarse aggregate can be secured only at a very high cost; and that, under such condition, it might be well to prepare concrete without the use of coarse aggregate, increasing, when necessary, the cement-aggregate ratio so as to secure the desired physical properties in the concrete.

This condition suggested the need for an investigation to determine how the compressive strength of the concrete varies with the relative quantity of cement when the maximum size of the aggregate used in the preparation of the concrete is considerably smaller than that usually employed in concrete construction. Accordingly, four series of tests were made in the manner and with the results described in this bulletin.

II. Scope Of The Investigation

The object of the investigation was to determine the ultimate compressive strength at 28 days of concrete prepared of fairly well graded aggregate the maximum size of which varied from one-eighth to one-half inch. In addition, tests were made for the purpose of determining something of the effect of additional water on the strength of the concrete, and also the effect of rodding the concrete in which excess water was used. A few tests were made for the purpose of comparing the strength of 6 by 12-inch cylinders with that of the 2 by 4-inch cylinders used for the majority of the specimens.
