 · The extensive use of bigger sandcrete blocks makes it very difficult for small-size standard bricks to compete with it . On the other hand, clay bricks cannot be made in bigger sizes due to danger of cracking on drying and burning which is an inherent property of clay, unless brick is made hollow or perforated.

cement, sandcrete block is made of only fine aggregate (sand) mixed with cement. The sand and cement mixture is in the proportion of 6:1 (British Standards Institution, 1970). Specifications for moulding sandcrete blocks stipulate that the block is generally to be made in accordance with BS 2028. Sandcrete blocks are made in three sizes in Nigeria.

Sandcrete blocks were made with a mix ratio of 1:6 (i.e., 1 part of cement and 6 parts of sand) and water (0.50 workability). Every necessary procedures and cautions for good masonry wall units were ensured with 25 strokes of blow for sound compaction. Finally, metallic flat base was used to further compact the mold mixture

Most office buildings in the warm-humid sub-Saharan countries experience high cooling load because of the predominant use of sandcrete blocks which are of low thermal mass in construction and extensive use of glazing. Relatively, low night-time temperatures are not harnessed in cooling buildings because office openings remain closed after work hours.

Sandcrete blocks comprise of natural sand, water and binder. Cement, as a binder, is the most expensive input in to the production of sandcrete blocks. This has necessitated producers of sandcrete blocks to produce blocks with low OPC content that will be affordable to people and with much gain. The poverty level amongst West African Countries and particularly Nigerian has made these blocks ...

Some Disadvantages. Concrete homes tend to be a little bit more expensive to build than other homes. It does pay off in energy costs in the long run, but may be out of reach for some potential home owners. The price of concrete fluctuates and will also vary depending on the region, so there isn''t a set price for concrete homes across the country.

 · The amount of cement calculated in Table 13.1 for the two soil types was high for Aviele laterite soil and outrageous for Ubiane soil, which ranked close with sandcrete blocks; almost one 50-kg bag of cement goes for every 1-m 2 area of wall of an earth building. This raises sustainability issues in earth construction system. The SCEB shown in the green area of Table 13.1 reduced considerably ...
