·The objective of this research is to enhance the two significant characteristics of Gypsum Plaster which are Density and compressive strength A parametric study for Water / Gypsum ratios % % and Chopped Carbon Fibre % % were carried out to investigate this parameters on density and compressive strength of Gypsum
·The utilization of gypsum reinforced composites as building materials has garnered considerable attention owing to their exceptional amalgamation of mechanical strength fire resistance and versatile applications This review initiates by introducing gypsum as a pivotal mineral in construction subsequently exploring the concept of composite materials and
·This study tends to optimize and develop an innovative gypsum material by incorporating hybrid waste compounds Using a Doehlert design this work explores the effects of introducing paper X 1 polystyrene X 2 and polyester fibers X 3 as well as their interactions on gypsum s thermophysical and mechanical density thermal conductivity
Gypsum bodies produced by this new process have high density and are mechanically stronger For gypsum plates having 3 density their strengths to bending and compression were found to be as high as and MPa respectively The new process can produce denser and stronger bodies by adjusting the compacting pressure
·In order to study the physical and mechanical properties of gypsum rock samples in three states natural high temperature dehydration and hydration time natural gypsum rock was put into high temperature condition of 220°C for dehydration treatment and then the high temperature dehydrated gypsum rock was treated with different hydration time and the
·High strength gypsum was obtained by the autoclave method [20] Briquettes in the form of cylinders with a height of m and a diameter of m were prepared This refers to the mechanism of crystallization of calcium sulfate dihydrate from solutions high density liquid precursors > hemihydrate nuclei > amorphous gypsum
·Density g/cm 3 v Longitudinal wave velocity m/s Grade α high strength gypsum powder produced by Sichuan Hongtai Biochemical Co ltd Nanchong China was selected Its main component is CaSO 4 · 2 O A block was prepared according to a ratio of water to paste of 3 10 and a standard sample was processed The processed samples
·Results show that the addition of calcined FGD gypsum and active calcium aluminate is able to improve the early compressive strength but using more FGD gypsum and a high sulfur aluminum ratio
