US: Researchers at Princeton University have developed cementitious composites with 17-times greater toughness and 19-times greater ductility than ordinary Portland cement (OPC). The materials are laser-processed into a grooved structure and laminated with elastomeric polyvinyl siloxane interlayers. The design is inspired by the nacre inner lining of seashells, also known as mother-of-pearl. This results in the toughening mechanisms of interlayer deformation, tortuous crack propagation and crack bridging. The composites have fracture toughness of 73.7MPa.mm^1/2, without any reduction in strength compared to OPC.

Taiwan: Japan-based Kataoka Corporation has successfully carried out an order for US$43.4m-worth of equipment for Taiwan Cement Corporation. Reuters News has reported that the order consists of cement plant machinery.

Kataoka Corporation is a developer and producer of laser processing systems and rechargeable battery inspection systems.
