ANISOTROPY OF CONCRETE

Anisotropy and heterogeneity characteristics of concrete were investigated by splitting tensile tests on cube or prism specimens. The tensile strengths, when the stress was applied in the same direction as casting, were lower than those when the stress was applied at right angles to the direction of casting, and in the former case those in the top portion were lower than those in the bottom. Considering that the direct cause for the anisotropy is voids under aggregate particles, the quantitative relations between the degree of anisotropy and setting shrinkage characteristics of fresh concrete were investigated. Consequently it may be macroscopically stated that the anisotropy characteristics of concrete depend on the degree of bridging of coarse aggregates and bleeding characteristics of mortar within fresh concrete. /Author/TRRL/
