Different Types of Mortar and Tests on MortarDifferent Types of Mortar and Tests on Mortar

Mortar is an intimate mixture of binding material, fine aggregate and water. When water is added to the dry mixture of binding material and the inert material, binding material develops the property that binds not only the inert material but also the surrounding stones and bricks. If the cement is the......

The Properties of Ordinary Portland Cement and Physical Tests on CementThe Properties of Ordinary Portland Cement and Physical Tests on Cement

Cement is a commonly used binding material in the construction. The cement is obtained by burning a mixture of calcareous (calcium) and argillaceous (clay) material at a very high temperature and then grinding the clinker so produced to a fine powder. It was first produced by a mason Joseph Aspdin in......

Determining the Specific Gravity of a Fine Grain SoilDetermining the Specific Gravity of a Fine Grain Soil

The specific gravity of soil grain is the mass ratio of the volume of dry soil in the pressure of air to the mass of the water of equal volume. Water is taken to be reference with a specific gravity of 1g/cm^3. The specific gravity of soil sample helps us to......

Testing for the Workability of ConcreteTesting for the Workability of Concrete

Workability of concrete is defined as the ease and homogeneity with which a freshly mixed concrete or mortar can be mixed, placed, compacted and finished. Strictly, it is the amount of useful internal work necessary to produce 100% compaction. Another similar term used to describe a freshly prepared concrete is ‘consistency’......
