Abstract
It is an established fact that additives when used in certain proportions, improve the desired properties of cement. Indian Standard (IS-269) for 33, 43 and 53 grades Ordinary Portland Cement has made a provision to add ten different kind of performance improvers and addition of these is limited to maximum 5%. Consequently, different manufactures use various materials as performance improvers depending upon suitability and cost effectiveness with sustainability. Another advantage is from environment point of view as substantial quantity of wastes (by products of various other industries) are converted to value added product. In the current study various types of mineral additives such as limestone, granulated blast furnace slag, lignite fly ash, kiln return dust, marine gypsum are used to improve the performance of 53 Grade Ordinary Portland cement (OPC). The results show that using these additives increase the performance of cement besides the saving in natural resources and thermal energy.
