The Utilization Of Crushed Stone Dust As A Replacement Of Sand In Cement Concrete
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 9
Abstract
In concrete as a composite material, the workability for placement and strength development with age depend upon the properties of the constituent materials and their combined action. The role of fine aggregate on strength and workability has to be deciphered before examining the possibility of total replacement of fine aggregate. The author’s content that stone dust can completely replace sand provided the mixes are repro-portioned to comply with practical requirements. A strong case is made out for greater and efficient utilization of stone dust.The purpose of mix proportioning is to produce the required properties in both plastic and hardened concrete by the most economical and practical combination of materials available. There has been very little use reported of the vast quantities of waste generated by mixing and quarrying industries. Only small amounts of these wastes have been used in road making and in the manufacture of building materials such as lightweight aggregate bricks and autoclaved blocks. An attempt is made to study the effects of stone dust ass fine aggregate on the strength and workability aspects of concrete mixes.It is evident that the concrete strength development depends upon the strength of the cement mortar and its synergetic with coarse aggregate. The applicability of the comprehensive approach, for proportion-quietly used or discarded presently such as stone dust has been highlighted.
