Abstract:
The last five years have seen a phenomenal improvement in concrete, both in design, manufacture and construction; the last ten years, due to the untiring work of such men as Abrams, Young, Talbot and others too numerous to mention, we have seen the general acceptance of the various theories covering the design of concrete mixtures upon a rational basis, the use of "fineness modulus” for grading of concrete aggregates, the general recognition and use of the "water-cement” ratio, the development of the slump cone and flow table for checking workability and consistency, a general improvement in machinery for the manufacture and handling of concrete, and we are now approaching the point where standardization of tests of cement, aggregates and concrete is being realized.
