Abstract:

Considerations of past performance of straight wire reinforced mortars in conjunction with some speculations as to the mechanism of short fiber action in concrete have suggested the use of a novel geometrical arrangement of fibers. . .Preliminary tests, using a far-from-ideal loop arrangment, show promise for greatly enhanced post peak strength, ducility, integrity and fatigue resistance when compared with regular concrete.

Abstract:

Most test procedures used to measure the effect of alkali reaction upon E-type of glass fibers in cement matrices bear little relationship between the test and actual field conditions. This paper seeks to establish a more meaningful test procedure and to demonstrate, as a result, that commercially available E-type of glass fibers may be safely formulated in cement matrices.

Abstract:

Full size concrete pipe were cast using steel fibers as reinforcement to either replace all or some of the conventional cage reinforcement. The direct tension test yields reasonable estimates of the tensile strength of fiber reinforced concrete as veirified by stress-strain relations of it and of the pipe test and by the spliting tensile test.

Abstract:

In conneciton with repair work for the Humboldt Jetties at Eureka, California, the San Fransico District, U.S. Army Corps of Engineers has performed tests to determine the relative strength of various precast concrete armor units.

SP44-23

Date: 

January 1, 1974

Author(s):

Publication:

Symposium Papers

Volume:

44

Abstract:

An investigation has been made into the effect of several variables of steel fibers on the flexural strength of concrete. Data is presented which shows the effect of fiber length, diameter, shape and content on both first crack and ultimate strength in concrete. Additional data shows the results of two field applications.
