A series of true triaxial tests were carried out with tsw-40 true triaxial apparatus to study the strength characteristics of silty clay under complex stress paths. The stress-strain curve of silty clay in true triaxial test was studied. This...

The fracture characteristics of crushed limestone sand ...

Clause 1590119, entitled fracture characteristics of crushed stone lime sand concrete, author Kim, J K and Lee, c s and park, c k and EO, s h Abstract note: due to the shortage of river sand, the use of crushed stone as fine aggregate has increased rapidly. Therefore, it is necessary to study the macadam concrete. In this study, the fracture characteristics of crushed concrete are studied...

Strength characteristics of crushed gravel and

As for aggregate materials, crushed limestone and crushed gravel commonly used in base applications in Illinois are considered. The Illinois dense graded base specification allows aggregate materials with a maximum size of 25 mm for CA 6 specification and 50 mm for Ca 2 aggregate.

Chapter 4 engineering classification of rock materials

According to the engineering characteristics, the rock unit does not have to conform to the officially recognized strata. The term rock unit is similar to that of rock body, because rock mass has consistent and mappable characteristics, but the difference is that rock body is formed under a single physical and chemical condition.

Characteristics of crushed rocks observed in drilled

According to the observation of borehole inclinometer, in addition to the gravel estimated to be caused by fault, there are other gravels showing composite plane fabric.

Characteristics of nickel laterite crushed ore ...

The heap leaching performance of complex copper gold ore was improved by using crushing and caking as pretreatment process. It is well known that proper agglomeration can prevent solution channeling and ponding and improve seepage

Influence of lateral loading on compaction

The broken waste rock can be used as backfill material in goaf to allow the reuse of other solid wastes and control the surface settlement. If a certain lateral stress is applied to the broken waste rock in advance, they will be densified. Therefore, in this study, the influence of lateral stress on the compaction characteristics of two-way backfill gravel is studied...

The engineering performance of crushed brick mixture is compared with typical Australian pavement subbase system specifications to determine the potential application of crushed brick mixture in pavement subbase system...

Mechanical characteristics and noise reduction ...

In order to study the mechanical properties and noise reduction performance of rubber concrete, on the basis of experimental analysis, the elastic modulus and strength index of rubber concrete with different content and particle size are studied, and the elastic modulus and noise reduction performance of rubber concrete are obtained...

Characterisation of cement treated crushed rock

However, it is unwise to use UCS to classify cement treated macadam, and can not describe the field behavior and characteristics of cement treated macadam base. Therefore, this paper studies the characteristics of macadam pavement in Western Australia. This is for the sake of

Creep characteristics and constitutive model of coal

Previous studies mainly focused on creep characteristics and constitutive models of rock, soil and concrete. The coupling effect of 2-10, 15-26, 31-33, 35-37 triaxial stress and gas pressure on creep deformation of coal is rarely seen. Study on creep characteristics of coal under triaxial condition...

Shear strength characteristics of crushed glass

Shear strength characteristics of cullet. Yes. Fred ray browning, 1946-a. Thesis. Submitted to the college. University of Missouri at Lola. Part of them meet the requirement of degree. MS in civil engineering. Approved in 1970 by Lola, Missouri. t2460。 c. Me. 73 years old. page

Frost durability and strength of concrete prepared

The effects of fine aggregate content, MB value of methylene blue and lithology of crushed stone CS on frost resistance and strength of concrete were studied, and the frost resistance and strength of gravel concrete CSC and river sand concrete RSC were compared. The results show that the addition of fine aggregate improves the compressive strength of C30 CSC and reduces the frost resistance of C30 CSC...

Through indoor frost heave test, Nie et al. It is pointed out that the frost heaving characteristics of graded crushed stone as subgrade filling are affected by water content, porosity and fine particle content, and water content is the dominant factor affecting frost heaving of graded crushed stone.

Analysis of stress

In order to study the stress-strain characteristics of multi-layer geogrid reinforced cushion, a new calculation method is proposed. Based on the hyperbolic model, the reinforced cushion is regarded as a nonlinear elastic body. The effect of reinforced geogrids is considered as equivalent additional pressure and is included in the gravel skeleton. Considering the friction effect between Geogrid and geogrid...
