Compression Test of Concrete ( From UTAR's Laboratory Practical) --- Part 2

From the compression experiment, every concrete we have taken down the record and result. Then we list it out and compare which one will be more hard and stiffness. Because we used different volume of material like sand, grave and cement to make many range of concrete. The total we have tried 6 different range of concrete like some is concrete is less of sand, some less of grave, some less of water, and some less of cement. From the diagram below we found the best result was the 1:1.5:3 / 0.6 concrete.

The six different range was

1:1.5:3 / 0.8 (275.5 kN)

1:1.5:3 / 0.6  the best result (364.4 kN)

1:2:4 / 0.8 (223.5 kN)

1:2:4 / 0.6 (229.5 kN)

1:3:6 / 0.8 (92.5 kN)

1:3:6 / 0.6 (110.6 kN)
