Sol-gel method was regarded as a kind of soft chemistry technique, by which fine powders would be obtained easily, meantime the amount of raw materials could be controlled accurately [2].
Experiment In this study, Sc2O3 (99.99%), Bi (NO3)3·5H2O (AR), Pb (COOCH3)2·3H2O (AR) and Ti(OC4H9)4 (AR) were chosen as starting materials to provide Sc3+, Bi3+, Pb2+ and Ti4+.
Besides, C6H8O7·H2O (AR), HNO3 (AR), NH3·H2O (AR), H2O2 (AR) were used as auxiliary materials.
Starting materials were mixed according to stoichiometric proportion of 0.365BiScO3-0.635PbTiO3 and sol solution was obtained.

Pozzolanic activity of materials and hydraulic waste are the main raw material for masonry cement.
These materials can be used to produce low-carbon cements.

Parametric finite element model of crane boom is built and uncertain parameters are obtained by analyzing characteristics of dimensions, materials, loads and constraint conditions for crane boom.
It is no doubt that material parameters are random for self-defects of material.
The material of crane boom is Q345.
