Sandcrete is usually used as hollow rectangular blocks similar to concrete masonry units, often 45 centimetres (18 in) wide, 15 centimetres (5.9 in) thick, and 30 centimetres (12 in) with hollows that run from top to bottom and occupy around one third of the volume of the block. The blocks are joined together with mortar. Strength and usage

1-6-2020 · The produced sandcrete blocks were cured for 28 days to allow for the development of sufficient strength of the blocks. Curing was done by sprinkling water on the manufactured blocks twice daily (morning and evening) and then covering with damp sacks in other to prevent loss of moisture and to allow for sufficient hydration of the binder.

COMPARISON OF LOCALLY EXCAVATED SAND .

In Nigeria, measured strength of commercial available sandcrete blocks was found to be between 0.5 and 1N/mm 2, which is well below the 3.5N/mm 2 that is legally required. This development may be due to the need of the manufacturers to keep the price low, and since the main cost-factor is the Portland cement, they reduce that, which results in a block that starts behaving more like loose sand.
