Manufactured sand (M-Sand) is a substitute of river sand for concrete construction . Manufactured sand is produced from hard granite stone by crushing. The crushed sand is of cubical shape with grounded edges, washed and graded to as a construction material. The size of manufactured sand (M-Sand) is less than 4.75mm. Why Manufactured Sand is …
This study aims to evaluate concrete having Waste Marble Powder (WMP) as partial replacement of cement. Marble is the metamorphic form of limestone (CaCO 3 ) and WMP was chosen as substitute of cement on account of its high calcium oxide content. WMP is by-product of marble industry and is an environmental burden.
— Pathan and Pathan reported that the slump of concrete mix reduces by the replacement of cement waste marble powder up to 20% but the slump is enhanced by the replacement of sand with the same percentage of waste marble powder. Replacement of 5% cement by WMP gives considerable strength but it reduces with the increase in …
