The rural and monumental architecture of Northern Spain gives testimony of the wide ranging constructive possibilities of traditional gypsum for exterior and structural applications However today gypsum is only used for finishing purposes By combining a bibliographic review with local visits/interviews and experimental gypsum calcinations we were
The ongoing global climate change and the associated environmental degradation pose a threat to Europe and the rest of the world Raw materials and energy are required to produce building materials which are used for construction purposes Resulting buildings and structures generate waste during construction operation and demolition and
The crushing of these low hardness gypsum particles also contributes to the reduced strength Therefore the UCS of the clay gypsum mixture decreases compared to the UCS of samples treated with the optimum gypsum content after the cation exchange capacity of the clay minerals is reached Several researchers studied the environmental
Gypsum is commonly applied as an ameliorant but there are few field studies into its long term > 10 years effects on soil chemistry especially at depths greater than m and no long term
Research shows gypsum in addition to other stabilization materials such as bagasse ash rice husk lime NaCl tin fly ash jute fibre etc produce a better stabilized soil as compared to gypsum or any of this material as stand alone stabilizer Journal of Civil Construction and Environmental Engineering 6 6 161 176 https //
