This paper presents the results of experimental investigations carried out on partial replacement of sand with
laterite as it affects the compressive strength of sandcrete hollow blocks. Two mix proportions (1:6 and 1:8) were
used with laterite content varying between 0 and 50% at 10% intervals. Hand and machine compaction
methods were used. Curing was done by sprinkling water on the specimens. The results showed that for each
mix proportion and compaction method, the compressive strength decreases with increase in laterite content.
Machine compacted hollow sandcrete blocks made from mix ratio 1:6 and with up to 10% laterite content is
found suitable and hence recommended for building construction having attained a 28-day compressive
strength of 2.07N/mm2 as required by the Nigerian Standards
