because raw material used in the making of Portland cement can be easily found and is available all over the world. Apart from that OPC is the cheapest among all other cementitious material available. Malaysia does not have much problem of existing sulfates in soil or groundwater‚ therefore usage of OPC is optimum to eliminate unnecessary cost spending ORDINARY PORTLAND CEMENT PROPERTIES The properties of concrete depend on the quantities and qualities of its components. Cement is the most active

Experiment 3: Enthalpy of Various Reactions Introduction A coffee cup calorimeter is an apparatus that is used to measure the quantity of thermal energy gained or lost in a chemical reaction. This experiment utilizes this apparatus‚ which is made from two styrofoam cups with plastic lids and a thermometer‚ to measure changes in thermal energy of various reactions. When using this type of apparatus‚ it is assumed that no heat is transferred between the calorimeter and the surroundings‚ and that

heat of solution reaction is similar to that is present when a hot metal is put into water. There is an exchange of heat between the reaction mixture and the solvent‚ water. The heat flow associated with the reaction mixture is also equal to the enthalpy change. One of the simplest reactions that can be studied in solution occurs when a solid is dissolved in water. Same with the neutralization of HCl
