2.2 Compressive Strength The result for the compressive strength of blocks is shown in Tables 2,3,4,5 and 6.Test rest indicate that the compressive strength of individual sandcrete blocks ranges between 0.11 N/mm2 to 0.75 N/mm2. The average compressive strength of the five blocks ranges between 0.14 N/mm2 to 0.66 N/mm2. These
requirements of a structure. The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures. The compressive strength is measured by breaking cylin-drical concrete specimens in a compression-testing machine. The compressive strength is calculated from the failure load
sandcrete blocks in Calabar Metropolis do not meet the minimum requirements for compressive strength set by the Nigerian Industrial Standard (NIS) and that of the British Standard Institution for masonry blocks. The study has also found that curing plays a vital role in improving on the compressive strengths of sandcrete blocks.
There is growing demand for alternative, low-cost building material in developing countries. The effect of partial substitution of ordinary Portland cement with Rice Husk Ash (RHA) on the compressive strength of hollow sandcrete block was investigated through laboratory experimental procedures.
Strength and usage. The final compressive strength of sandcrete can be as high as 4.6 N/mm 2, which is much less than concrete's 40 N/mm 2. Sandcrete is unsuitable for load-bearing columns, and is mainly used for walls, or for foundations if no suitable alternative is available.
production processes. Wenapereand Ephraim (2009) found that the compressive strength of sandcrete blocks increased with age of curing for all mixes tested at the water-cement ratio of 0.5. The strength at ages 7, 14, and 21 days were 43%, 75%, and 92% of the 28-day strength respectively. Much of the focus of researchers in this
