The highest compressive strength (9.1 MPa) at 28-day curing of the cement-laterite interlocking blocks was obtained at 5% sand replacement, which is about 13% increase in strength over the control ...
to an increase in the demand for sandcrete block. This in effect has consequently increased the demand for Ordinary Potland Cement (OPC) since cement is the main constituent in sandcrete block production yet it is expensive. OPC, as a constituent of the sandcrete blocks plays a vital role in the strength. However, the cost of the
using sandcrete blocks and interlocking blocks. Each unit comprised L-shaped wall measuring 3200mm x 600mm as shown in Figs 1(a) and 1(b). and the sandcrete blocks. The 1st batch was cured for 7days, Fig – 1 (a): Sandcrete block wall Fig - 1(b): Interlocking block wall Two masons, X and Y both skilled in sandcrete block wall
Hence, this study seeks to find a way of incorporating laterite in the production of sandcrete hollow blocks. Sandcrete blocks are constructional masonry units that have been generally accepted to the extent that when an average individual thinks of building, the default mind-set is the use of sandcrete hollow blocks.

Nov 21, 2018· Compressive strength of 2% cement content lateritic brick B and sandcrete hollow block Based on the above conclusion, it is recommended that Lateritic brick A should be commercialized for industrial uses. Generally, Laterite brick should be used for low cost building because it has high compressive strength than that of sandcrete hollow block.
Hollow sandcrete blocks containing a mixture of sand, cement and water are used extensively in many countries of the world especially in Africa. In many parts of Nigeria, sandcrete block is the major cost component of the most common buildings. The high and increasing cost of constituent materials of sandcrete blocks has contributed
The most common walling materials are conventional sandcrete blocks and fired clay bricks. The high cost of sandcrete blocks coupled with the low strength properties of commercially available blocks necessitates the development of an alternative brick material. In comparison to the use of sandcrete blocks…
Jun 01, 2021· The compressive strength of sandcrete blocks increases at elevated temperatures, indicating that elevated temperature up to 200 °C can enhance the compressive strength of sandcrete block. 3. The addition of micronized laterite up to 20 % in the cement-sand matrix produces sandcrete blocks of lighter weight.
