A H M 531 The Civil Engineering Center Objectives: To measure the mechanical stre ngth of cement by applying Compressive and Tensile tests on Cement-Sand mortar. Standards: ¾ Compressive strength of cement using mortar cubes: B.S.12 – Part 2 ASTM : C 109 ¾ Tensile strength of mortar using briquettes: B.S.12 – Part 2 ASTM : C 109 General Discussion: In these tests (Compressive and Tensile tests) we measured the mechanical strength of the hardened cement. These tests are done on

pdf Multi-Level Formwork Load Distribution with Post-Tensioned Slabs By Dr Stephen L Kajewski1 Abstract: Formwork and the associated shoring represent a significant proportion of the costs associated with the construction of multi-level concrete structures. To minimize these costs‚ a limited number of formwork and shoring sets are recycled up the structure as construction progresses‚ eliminating the need for a new set of formwork and shoring with each new slab. When a slab is post-tensioned

PRESTRESSED CONCRETE The development of early cracks in reinforced concrete due to incompatibility in the strains of steel & concrete was perhaps the starting point in the development of new material like “Prestressed Concrete”. Prestressed Concrete is a method for overcoming concrete’s natural weakness in tension. INTRODUCTION Prestressed Concrete is basically concrete in which internal stresses of suitable magnitude & distribution are
