Tests for mechanical and physical properties of aggregates - Part 8: Determination of the polished stone valuedoi:EN 1097-8:2020本文件描述了用于型式试验的参考方法,以及在确定路面用粗集料的磨光石值(PSV)有争议的情况下.对于其他目的,特别是工厂生产控制,只要与参考方法建立了适当的工作关系,就可以采用...
Because the hydrated cement paste amounts to only 24 to 43% in volume [8] of the constituent-materials comprising the concrete mix, the properties of concrete with temperature are found to vary widely with the types of aggregates used. Thus predicting the post-fire response of concrete is a...
Nevertheless, in order to seriously introduce household waste materials as a construction material in architecture, the professionals involved need to understand the properties of these materials in depth. In this sense, this project studies these properties in the case of waste-based alternatives ...
The overall physical properties of tissues emerge in a complex manner from the properties of the component cells and other constituent materials from which the tissue is formed, across multiple length scales ranging from nanometres to millimetres. Recent

gradually changes the structural properties of the fibrillar matrix, similar to what has been demonstrated for crosslinked actin networks33. Fig. 4: Collagen is plastically remodeled by the invading epithelium resulting in a stable collagen cage....
Several tests and procedures have been formulated to evaluate this reaction, particularly in terms of aggregate reactivity. However, the data given in the literature concerning the mechanical properties of concrete and mortar are scattered and very little information is available for some properties such...

The test results have shown that elevated temperatures had important effects on the mechanical properties of G0 and G5 specimens. Although the general trends of the influence of high temperatures on mortar properties were similar, residual compressive and flexural strengths, as well as modulus of el...
There is growing appreciation of the importance of the mechanical properties of the tumor microenvironment on disease progression. However, the role of extracellular matrix (ECM) stiffness and cellular mechanotransduction in epithelial ovarian cancer (EO
