Study on the Acoustic Emission Characteristics of the Concrete Cleavage;

Based on the structure of machine tools,the article studies the effect of split-tensile strength with different composition of bonds.

For studying the split-tensile strength of roller compacted concrete(RCC) and its size effect on meso-level,the random aggregate model was used and RCC was taken as three-phase heterogeneous composites consisting of mortar smut matrix and pulverized coal ash,aggregate,smut matrix plane and bond between matrix and aggregate on meso-level.

9kg/m3) is investigated in terms of compressive,axial compressive,and splitting tensile strength properties.

The effects of steel fiber volumetric ratio,steel fiber slenderness ratio and steel fiber type on the splitting tensile strength,axial tensile strength and axial tensile stress-strain curve of steel fiber reinforced concrete(SFRC) are studied.

Discreteness of splitting tensile strength of marble is very great and it is influenced by the factors such as heterogeneous,splitting type and size effect and so on.

To investigate the effect of fiber volume fraction on mechanical properties of carbon fiber cement composite,the compressive strength and split tensile strength are tested for different fiber volume fractions.

The varied compressive strength,flexural strength and split tensile strength of furan resin concrete of different durafiber volume content are studied.

The experiment focused on compressive strength,split tensile strength,flexural strength of pumice lightweight aggregate concrete of four types air content in the same water-cement ratio and dosage of cement.

For studying the split-tension strength and its size effect of concrete on micro-level,the random aggregate model was used to simulate the structure of concrete,concrete is taken as three-phase composites consisting of mortar smut matrix,aggregate and bond between matrix and aggregate on micro-level.

This article chiefly investigates the relation of compressive strength and cleavage tensile strength to the doping percentage of carbon fiber in carbon fiber reinforced concrete.

Based on the optimum design of mix proportion for Dry-mixing Self-Compacting Concrete(DSCC),cube compressive strength and cleavage tensile strength were investigated.
