Oil-well lightweight cement slurry for improving compressive strength and hydration rate in low-temperature conditions

Inadequate early compressive strength is a common problem when employing lightweight cement (LWC) slurries during the cementing of oil wells under low-temperature conditions. A new formulation of LWC slurry was investigated by the Research Institute of Petroleum Industry (RIPI) to improve the compressive strength and hydration rate of LWC...

Design to fabrication integration and material craftsmanship - A performance driven stone architecture design system based on material, structural and fabrication constraints and criteria

This paper presents a computational design methodology through describing of a case study on stone building system. In addition to establishing a performance driven form-finding methodology, the objective is to redefine local craftsmanship methods as industrial fabrication techniques in order to introduce the constructability of the design...
