Investigation on Properties of Concrete with Crushed
Crushed sand, on the other hand can only be used as fine aggregate when VFS(Very Fine Sand) is below 35 percentage of weight of sand and particle shape is above 55 percentage This study is to investigate the properties of concrete with crushed sand on site and to propose a quality guideline for its use as artificial sand and concrete From our experimental result in laboratory and site, we found that demand water of concrete with crushed sand for target slump increased by 18kg/m3 compared to mixed sand and l8kg/m3 compared to sea sand respectivelyInvestigation on Properties of Concrete with Crushed The Concrete has been traditionally made with use of Natural / River sand as fine aggregate As sand contributes to around 25 to 35% of total concrete along with coarse aggregates, cement water, the properties of the fine aggregates would be one of the major influencing factor in determining the fresh hardened Concrete Read More »Use of Crushed Stone sand its impact on Concrete Use of Crushed Stone sand its impact on Concrete An Experimental Investigation On Properties Of Concrete By Partial Replacement Of Cement With Dolomite And Sand With Crushed Sea Shell April 2020 International Journal of Scientific Technology (PDF) An Experimental Investigation On Properties Of Concrete, M Sand, Metakaolin, Silica Fume, Steel Fibers Cite this Article: Ajay Shelar, Dr D Neeraja and Dr Amit B Mahindrakar, Experimental Investigation of Crushed Sand in Strength Supporting Self Actualization of Concrete International Journal of EXPERIMENTAL INVESTIGATION OF CRUSHED SAND IN
