Variation of Physical Properties of Cement over Time

Riazul Haque, Sumit Purkayastha, and Abdul Muktadir Khan

Abstract—Cement, a binding material, is considered the key ingredient of concrete which is used in construction. Physical properties of cement indicate the quality of cement. But these properties change after a certain period, which may lead to unsuitability of use in construction. In the experiment, physical properties of cement like normal consistency, setting times, fineness, soundness and compressive strength have been determined following ASTM (American Society for Testing and Materials) & BDS EN (Bangladesh Standards Engineering Division) standards. Experiment has been carried out for two types of cement sample- PCC (Portland Composite Cement) 42.5N and OPC (Ordinary Portland Cement) 52.2N, using two standards on the same day at 0th, 4th & 8th week from the manufacturing date of cement. Maintaining a controlled environment of humidity and temperature in the laboratory, change of physical properties over time has been analyzed from November, 2016 to January, 2017. The experimental result shows that the cement remains perfect for use till 8th week (approximately 2 months) from the manufacturing date and the values of physical properties remain within the specified range of ASTM & BDS EN standards; except the compressive strength of PCC 42.5N, which is lower than that of BDS EN standard.

Index Terms—ASTM and BDS EN standards, compressive strength, OPC 52.5N, PCC 42.5N, physical properties.
