This paper presents the results of laboratory tests conducted to investigate a concrete made with laterite rock coarse aggregates. The structural properties considered were strength and elasticity. Laterite concrete mix proportions of 1:3:6, 1:2:4 1:1½:3 by weight of cement, river sand and laterite rock respectively at varying water/cement ratios of 0.55-0.90 were used.

The compressive strength of sharp sand and stone dust bottle bricks at 0% moisture content is comparable to the compressive strength of common blocks and only achieved the minimum 2.9 N/mm 2 compressive strength recommended in BS EN 771–3 for masonry. Unlike laterite bottle bricks, the results have revealed that moisture content up to 20% is required in the production of sharp sand or stone ...

The following conclusions can be drawn from the investigations carried out on the effect of aggregate variation on the compressive strength of lateri- te concrete ; (i) laterite can be used as a substitute for river sand in making concrete since there is not much difference between the laterite concrete and normal concrete, with river sand, in strenghts achieved. (ii) the arithmetical method ...

It is seen that the compressive strength of laterite from Malabar region shows wide variation (1.3 - 4.5 MPa). The strength properties are comparable with that of ordinary bricks (3.5 MPa). High moisture absorption of the material (up to 17 %) suggests that the material can hold and conduct large amount of water, which promotes the growth of vegetation and microorganisms. The reduction in ...

2) The compressive strength of laterite is around 120 Kg/sqcm. Taking this strength, the thickness required will be very less. However, the charcter of laterite is so that a minimum thickness of atleast 30cm will be required to avoid breaking when quarrying out.

Specifically compressive strength ranged from 17-34.2 N/mm for the mixes considered. These results compare favourably with those of conventional concrete. The concrete was found to be suitable for use as structural members for buildings and related structures, where laterite content did not exceed 50%.
