In case of field density test by sand replacement method the steps involved for calculation are as follows:. Field Density test Calculation in Sand Replacement Method “The basic aim of field density test calculation is to find the in-situ weight of the soil that is obtained either by core or by sand metal tray which is divided by the in-situ volume of the excavated hole”

In this post I will elaborate how to calculate a compaction test report in case of sand replacement method as well core cutter method. The foundation compaction is either accepted or rejected based on this degree of compaction. Field Density Test Methods Methods of Field Density Test No worries at all ! Because I have made a comprehensive guide explaining different methods of field density test and their pros and cons. This density is than compared with the maximum dry density achieved in laboratory by Modified Proctor Test – this comparison is termed as “degree of compaction” in field density test calculations. The basic purpose of field density test calculation is to know the density achieved at site with the help of mechanical compaction equipment. Sand replacement method or sand cone method.The most common methods used at site for this purpose are:. The degree of soil compaction is evaluated at site with the help of field density tests and bulk density of soil as well as degree of compaction is calculated. Whether you are about to found the footing of a building on soil, or is working on a dam project where roller compacted concrete is used or you are working on a highway project where subgrade is being prepared you need a criterion / procedure for quality control of the foundation.
