The paper presents the results and assessment of properties capabilities new types surface hydrophobic agents for treatment fresh matured surfaces concrete other cement-bound layers. Hydrophobisation prevents premature evaporation water thus plastic shrinkage, which inevitably leads to formation cracks in cement-based structures. influence type agents, epoxy water-based (EWH) acrylate (AH) cont...

It is well established that Self-Compacting Concrete (SCC) contains large amounts of fines including mineral admixtures, such as fly ash and slag, in order to avoid segregation increase cohesion. The use these materials concrete reduces CO2 emissions contributes towards sustainable construction. To overcome the negative effect slag on strength development was ground three finenesses. Therefore,...

For years, geotechnical engineers have been concerned about expansive soils. Expansive soils are characterized by large volumetric changes related to variations in moisture content. Variations soil water content may take place naturally during seasonal or maybe manmade caused dewatering activities. The quantity of shrinkage and swell is influenced numerous parameters, including the minerals cla...

Wood shrinks anisotropically as it loses hygroscopic moisture. While longitudinal shrinkage (parallel to the grain) is nearly negligible in normal wood, transverse shrinkage (across the grain) is significant and characterized as tangential and radial shrinkage. The application of average tangential shrinkage values to a rectangular cross section results in errors, especially for boards cut from...

This paper proposes a novel image denoising technique based on the normal inverse Gaussian (NIG) density model using an extended non-negative sparse coding (NNSC) algorithm. Here, we demonstrate that the NIG density provides a very good fitness to the non-negative sparse data. In denoising process, by exploiting a NIG-based maximum a posteriori estimator (MAP) of an image corrupted by additive ...

Nanoporous gold (NPG) made by dealloying takes the form of a network nanoscale struts or “ligaments”. It is well established that material’s mechanical behavior strongly affected its ligament size, L and solid volume fraction, ?. We explore NPG, with an emphasis on establishing consistent data set comparable but covering significant range initial Specimens are prepared from Ag-Au master alloys ...

Abstract Growing application of artificial intelligence in geotechnical engineering has been observed; however, its ability to predict the properties and nonlinear behaviour reactive soil is currently not well considered. Although previous studies provided linear correlations between shrink–swell index Atterberg limits, obtained model accuracy values were found unsatisfactory results. Artificia...

This study was conducted to determine whether novel experimental low-shrinkage dimethacrylate co-monomers could provide low polymerization shrinkage composites without sacrifice to degree of conversion, and mechanical properties of the composites. Experimental composites were prepared by mixing 28.6 wt% of bisphenol-A-glycidyl dimethacrylate based resin matrix (bis-GMA) with various weight-frac...
