It should be assumed that two types of cement meeting the same minimum requirements will produce the same strength of mortar or concrete without modification of mix proportions. Time and strength gain: time and strength of cement relationship are non linear. 1) 1 day of curing time cement gain its strength about 16% of total strength

Date: 12/1/1961. Abstract: In 1910 a test program was undertaken at the University of Wisconsin to obtain information on the effect of age and certain curing conditions on the compressive strength of concrete. Specimens from this investigation were made of different mixtures and made underwater out of doors, or indoors.

Compressive strength: Compressive strength is an important indicator of the mechanical properties of planting concrete. To test the compressive strength of the planting concrete, cubic samples of planting concrete with dimensions of 150 mm × 150 mm × 150 mm were used . There were three specimens in each group, and a total of 30 specimens were ...
