One application, only in-situ soil mixing (or deep mixing method, DMM) is becoming increasingly common as an economical construction method for temporary support of deep foundation excavations and is also used in the construction of permanent retaining walls. Steel beams placed into the fresh soil/cement are generally used as the primary structural support, later supplemented with bracing or ti...

background: soil pollution and accumulation of heavy metals in crops in industrial areas is one of the most important environmental issues threatening the life of plants, animals, and humans. the aim of this study was to determine the concentration of cr and cd in the soil and barberry plants in farms surrounding the qayen cement company, south khorasan province, iran. materials and methods: in...

This paper explains the procedure and results of an experiment on the relationship between the unconfined compressive strength and percent weight loss due to freeze and thaw durability test of laboratory compacted soil-cement specimens. The tests were carried out on soil cement mixtures of 10 different soil types. It was shown that the percent weight loss due to freeze and thaw durability test ...

In this study, unconfined compression tests have been conducted to investigate the impacts of copper slag on mechanical characteristics for stabilized cement and un-stabilized soil. Dozens of specimens were prepared at four percentages of cement (i.e. 0%, 2%, 4% and 6%) and five percentages of copper slag (i.e. 0%, 5%, 10%, 15% and 20%) by weight of dry soil. The samples compacted into a cylind...

The mechanical property of the pile-core–cement-soil interface is a crucial factor affecting shaft capacity expanded stiffened deep-cement-mixing (ESDCM) pile. research on characteristics steel-pipe–cement-soil very limited, and conventional concrete–cement-soil results cannot provide direct guidance for engineering application combination Hence, in this study, we employed model pile with combi...

Cement-soil is a common method to strengthen soft soil foundation. In engineering construction, certain amount of fiber often added improve its mechanical properties. order evaluate the fatigue damage properties soil-cement materials under cyclic loading, basalt and polypropylene were into in this experiment carry out material test loading. The results show that compared with plain soil-cement,...

This study aimed to evaluate the influence of adding plastic bottle fibers soil-cement mixtures and possible improvements generated by addition a blend two types additives, namely, additive 1 (waterproofing improver) 2 (adhesion enhancer), in compactability shear strength parameters soil-cement-plastic fiber mixtures, considering tropical residual soil. The used this are made Polyethylene Terep...

PS silt mixed soil is a high quality synthetic fill material made of foam material and sludge wasted. This paper indicates according to the test results and the previous studies that: the intensity of light-weight soils is increasing as the grey water ratio increases, and when the gray water ratio reaches a certain value, the strength of the growth rate is not large. Therefore, the research of ...
