Isi artikel

Portland cement mortar (PCM) is made up by mixing portland cement (PC), water and fine aggregate. Production of PC, active material to create binder in PCM, releases CO2 emission to environment. Approximately, the amount of CO2 released to the environment is equal to the amount of PC produced. Optimum use of PC in PCM in order to achieve a certain level of compressive strength will decrease CO2 emission to environment. In the system of PC binder-fine aggregate, compressive strength is affected by the volume of porosity (while all mortar constituents are chemically and physically kept same). The amounts of porosities mainly come from capillary porosity (affected by w/c) and interfacial transition zone (affected by w/c and quantity of PC binder in PCM). During the course of current study, investigation is made on influence of quantity and quality (w/c) of PC binder on compressive strength of mortar after 1, 3 and 7 days. Five different levels of w/c and PC binder quantities are included.
