AN EXPERIMENTAL STUDY OF THE PROPERTIES OF MICRO-CONCRETE WITH PIT SAND

In order to check the suitability of the local materials of construction and to study quantitatively the strength and other relevant properties so that proposals could be put - forward regarding the permissible/characteristic values of stresses etc , that could be entered into calculations while designing a particular structure with these materials as basic constituents, the authors tested a few hundred specimens of micro - concrete containing both; hill sand , and the pit - sand in its purest form as fine aggregate and the Portland cement as binding material . The micro - concrete with pit - sand as fine aggregate has been in use for less important works in plain areas of our  country where the hill sand is not readily available; although its standard technical data is not available so far. The full details of the experimental study is presented in the following sections .
