The compressive strength of AAC block masonry is less than that of the compressive strength of individual AAC block. The average compressive strength of masonry using different proportions of cement–sand mortar ranged from 1.96–2.58 N/mm2(MPa), whereas the average compressive strength of individual AAC block is ranging between 3 to 6 N/mm2.

The compressive strength for all the nonconventional blocks is presented in Fig. 7. From Fig. 7, it is observed that the block compacted with waste plastic, fly ash, and quarry dust resulting higher compressive strength compared to PFS and conventional cement block. The highest strength observed for the PB-2 block as 50 MPa and 14 MPa for CB-3.

The maximum compressive strength value which is obtained from the mixture of sinabung ash is 41.60 Mpa, it was obtained from a mixture of 15% sinabung ash. From the use of these two materials, paving blocks produced are classified as paving blocks quality A and B (350 – 400 Mpa) in accordance to specification from SNI 03-0691-1996.

The vibropressing process shows a significant and linear growth in compressive strength with increase vibrations and frequencies. The conclusion is that the compressive strength of paving block concrete is very dependent on blocked in terms of the frequency and duration of vibrations.

CBP is formed from individual concrete paving blocks (CPBs) that fit next to one another on a suitable sub base leaving a specific joint space among them to be filled with jointing sand. CBP differ from other pavements according to their mechanical behavior, manufacturing technique, structural design, installation technique and structural behavior.

The compressive strength of normal concrete paving bricks is 41.60 Mpa. This means that these bricks can withstand a lot of pressure before they break. This is important because the bricks create a seal between the concrete and the ground. If the bricks break, the concrete will seep through, and the project will likely fail.
