You can  ask yourself what is the index properties of soil? Is it helpful to know the index properties of soil? The answers of above questions can be answered as described below INDEX PROPERTIES OF SOIL These are properties of soil which are not primary interest to Geotechnical Engineers but which are indicative of the engineering properties of soil,  these properties of soil have nothing to be used in design but they are helpful in one way or another. The following are examples of index properties of soil which can be indicative of engineering properties of soil. 1.       Specific gravity Specific gravity of soil (G) is ratio of density of soil to density of standard material (water) . Specific gravity of soil help geotechnical engineers to know the porosity of soil and to predict whether the soil will be stable to support the structure and allow proper drainage . 2.       In-situ bulk density This is the density of undisturbed soil (s

ONE WAY AND TWO WAY SLABS IN BUILDING CONSTRUCTION INTRODUCTION Multi storey buildings are made of structural skeletons and finishing, the structural skeleton of the building ensure the safe and stability of the building, finishing of the building bring the beauty and functionality of the constructed building. The structural skeleton is the one that transfer loads from people, furniture, and other things to the foundation, structural skeleton consist of beams, columns, slabs, and pads. Slab receive loads from people, furniture and other things as they rest on it, the load is then transferred to the beams that support slabs, from the beams the load is transferred to columns then to constructed foundation and finally to natural foundation that is soil. The slab used in multi storey buildings can be any of two systems which is either one way slab or two way slab system, these systems are used in accordance to the distances at which slabs should be placed. ONE WAY SLA
