A total of 108 specimens of 25 × 25 × 275 mm prisms and 98 specimens of 75 × 150 mm cylinders of mortar collected from ongoing construction projects in Riyadh were cast and tested. It was found that under the same curing conditions and for same mix proportions white sand produces mortar with higher modulus of elasticity and lower drying shrinkage. For instance, replacing 50 or 100% of red sand by white sand increases the modulus of elasticity and reduces the drying shrinkage by more than 50%. This implies that white sand mortar is more stable than red sand one.  ISSN : 1319-1047  Journal Name : Engineering Sciences Journal  Volume : 11  Issue Number : 2  Publishing Year : 1419 AH 1999 AD  Article Type : Article  Added Date : Thursday, January 28, 2010  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email محمد أمين أمجد AMJAD, MOHAMMED AMIM Researcher Doctorate   Files File Name Type Description  24934.pdf pdf Elasticity and Shrinkage of Cement: Sand Mortar Produced in Riyadh Back To Researches Page
