The application of grouting technology in housing construction is to inject liquid grout into the cavities and cracks construction. After it solidifies, stability can be improved. Grouting not only very convenient but also environmental-friendly, relatively low-cost. Therefore, widely used In this paper, types its advantages are analyzed, specific strategies put forward, hopes improving quality

Acrylate is a popular polymer grouting material that has been widely used to control groundwater seepage. However, the vulnerability of acrylate slurry dynamic water washout restricts its application in environments characterized by high flow velocity and pressures. In this paper, lithium bentonite (Li-B) was modify traditional magnesium (AC) material. The influence Li-B AC ratios on modified m...

Common approaches to the simulation of Borehole Heat Exchangers (BHEs) assume heat transfer in circulating fluid and grout to be in a quasi-steady state and ignore fluctuations in fluid temperature due to transport of fluid through the loop. However, the dynamic responses of circulating fluid and BHEs have important implications for systems design under some circumstances. This paper presents a...

The influence of different modelling assumptions on the results of numerical analyses of a deep excavation problem is discussed. Based on a reference solution a comprehensive parametric study is performed, identifying modelling assumptions which may have a significant influence on the calculated displacement behaviour and the bending moments in the wall. The parameters investigated include wall...

Reinforced masonry (RM) walls are mostly used in low to mid rise residential/industrial buildings cyclonic and seismic regions. They conventionally constructed with grout embedded vertical steel reinforcements positioned the middle of hollow blocks. However, these reinforcing bars rarely detailed lateral restrainers, which considered essential design standards avoid buckling bars. This research...

A new species of the genus Akodon is described from Puno and Cusco departments, southern Peru. It appears to be similar and perhaps closely related to Akodon fumew, a species that inhabits the eastern slopes of t...

The type of lightweight aggregate and its volume fraction in a mix determine the density of lightweight concrete. Minimizing the density obviously requires a higher volume fraction, but this usually causes aggregates segregation in a conventional mixing process. This paper proposes a two-stage casting process to produce a lightweight concrete. This process involves placing lightweight aggregate...
