Dynamic Loading of Soil-Cement for Flexible Pavement Design
Stabilised soil-cement has been used in road pavements for considerable time. Certain design criteria concerning the properties of the material have been established. However, there is little knowledge of the material's behaviour under dynamic loading conditions simulating traffic loads. The aim of …

Seismic Response of Structures on Shallow Foundations over Soft Clay Reinforced by Soil-Cement Grids
… analyses to: (1) evaluate the effect of soil-cement grid reinforcement on the seismic response of a deep soft soil profile, and (2) to examine the dynamic response of structures supported by shallow foundations on soft clay reinforced by soil-cement grids. The soil profile consisted of a …

Development and performance of self-healing and self-immune soil-cement systems subjected to freeze-thaw cycles
Soil-cement systems are used in a wide variety of engineering projects. However, soil-cement systems are vulnerable to cyclic freeze-thaw deterioration. The engineering properties of soil-cement systems, such as strength and permeability, can be substantially degraded under the action of …

Estudo da fadiga de duas misturas de solo-cimento
… tensile test, for two differents tipes of soil-cement: lateritic soil-cement mixture and saprolitic soil-cement mixture. Fatigue curves, in terms of stress, strain and stress level, were developed for the two stabilized materials, of each repeated load-test. A comparision was made, of the …

Optimization of Soil-Lime and Cement Mixes for Compressed Earth Stabilized Blocks for Low-Cost Housing in East Africa (Kenya)
… materials has made housing to be scarce. Cement is two to three times the cost of construction lime in East Africa, thus the need to maximize the use of lime. Conventional building materials (fired bricks and concrete blocks) have proved to be expensive and unsustainable; stabilized earth …

Contribuição ao estudo do Método físico-químico de dosagem do solo-cimento
… method known as Physico-chemical Assessment of Soil-Cement, by using four soils of lateritic weathering with different characteristics. The method's precision was appraised by means of repeatability and reproducibility indicators. For this purpose, ten assays were made on each soil with the same …

Fracture Characteristics of Concretes and Cement-Stabilized Soil
… or fracture toughness of concrete, mortar, or cement paste, failing in tension. Studies on an experimental determination of fracture toughness for concrete subjected to a compressive stress field have limited report so far. This project applies the concept of linear elastic fracture mechanics …

Iniciação e propagação de fraturas induzidas por injeções em solos argilosos com canalículos: aplicação ao tratamento do solo residual de fundação da barragem de terra da UHE Balbina
Due to the pecularities of the residual soil at the Earth Dam Foundation at Balbina Power Plant, in which zones of high values of permability (K ≥ 10-³ cm/s) were found to be intimately connected with the existence of Small Channels, it was decided to treat the foundation with a soil-cement grout …

Using BCSA Cement to Repair Waterway Transportation Structures
… BCSA (belitic calcium sulfoaluminate) cement is a promising material to perform this type of repair due to its properties. BCSA cement is a fast-setting hydraulic cement capable of reaching compressive strengths greater than 4000 psi (27.6 MPa) in less than 2 hours. BCSA also has low …

Estabilização de areia com adição de cal e cinza volante
… uniform sand. Timing at the action of fly ash, a soil with no cohesion, lacking of colloidal fraction, was chosen. This soil is not suitable for the usual processes of stabilization with portlant cement or lime. The fly ash - a residual material from the burning of pulverized coal - and lime, when …

Performance of Columnar Reinforced Ground during Seismic Excitation
Deep soil mixing to construct stiff columns is one of the methods used today to improve performance of loose ground and remediate liquefaction problems. This research adopts a numerical approach to study seismic performance of soil-cement columnar reinforcements in loose sandy profiles. Different …

The use of Sardinian granite by-products from the Sarrabus Gerrei region to be used in road pavement layers
… both hydraulic and bitumen binders were studied. Soil-cement mixes were prepared using different percentages of Portland cement performing different. Then Hot Mix Asphalt (HMA) samples were analysed in order to evaluate the affinity between granite and bitumen. Difficulties were emerged using this …
