In the laboratory, a paste specimen was prepared using 45 g of water and 100 g of cement then sealed to prevent the loss of water. The paste specimen was cured for 28 days in the constant room temperature. After the 28 days of curing period, a sample from the paste specimen was obtained by breaking off the specimen and the sample was dried in the oven at 105°C for 24 hours. After this oven drying, the sample was then...
