Effect of Methylmethacrylate and Ethylenediamine on the Physicomechanical Properties of High Strength Portland Cement

Effect of Additives on Portland Cement

Abstract

In the study of the effect of methylmethacrylate (C5H9O2) and ethylenediamine (C2N2H8) on the physicomechanical properties of high strength Portland cement, addition of methylmethacrylate upto 5% strength showed negative effect on the bulk density, cold crushing strength and hydration of the cement; however, the negative effect was relatively less in case of lower concentrations (< 2%). Addition of ethylenediamine upto 3% concentration showed remarkable increase in these properties.
