Manufactured sands can be classified into different lithology based on the diverse parent rocks. Some key properties such as crushing index and water absorption rate of manufactured sands are closely related to the parent rock's performances. Consequently, the lithology of manufactured sand may have a certain influence on concrete properties.

Purchasing a manufactured home is an exciting first step towards watching your vision of homeownership become a reality on your very own land. But before the big day arrives, there's crucial preparation involved to ensure a smooth and successful installation process. In this guide, we'll walk you through everything you need to know about site preparation for …
Non-uniform shrinkage of SiC precursors will lead to cracking and thus weaken the mechanical properties of the C f /SiC composites. This study used the pressure-assisted gel impregnation method to introduce SiC particles (SiC p) into the carbon fiber preform and combined the PIP technique to fabricate C f /SiC composites. The mechanism of enhancing …

The results indicated that the crystal form of CL-20 was retained as ϵ-form after wet grinding. The ground CL-20 was superior in physical properties to the raw CL-20, such as smaller particle size, smooth surface, less mechanical sensitiveness, and lower flame sensitivity. However, the thermal stability was slightly decreased.
