Study on Flyash Mixed Laterite-Cement Bricks
2019-7-1 compressive strength of Fly ash mixed laterite-cement brick is 9.5 N/mm2 which is 4.5 times higher than laterite stone. Thus, due to the higher compressive strength, the Fly ash mixed laterite-cement brick can be used as a load bearing walls. Keywords— Laterite soil, Fly ash, Laterite-Cement bricks, Laterisation

Lateritic cement- and lime-stabilised bricks and blocks
2018-9-18 Laterite is a soil layer that is rich in iron oxide and is derived from a wide variety of rock weathering under strongly oxidising and leading conditions. It forms in tropical and subtropical regions where the climate is humid (Encyclopaedia Britannica, 2016).

Lateritic soil based-compressed earth bricks stabilized
2020-9-1 The latter was used to make bricks by statically compaction in a prismatic mold (200 mm × 90 mm x 40 mm) at a pressure of 15 MPa for 10 s using a laboratory compacting machine (NANNETI). The obtained bricks were sealed into plastic bags and stored at room temperature (25 ± 3 °C) for seven days, then further cured at 65 °C for 48 h.

Use of Cement-Sand Admixture in Laterite Brick
2013-8-11 Based on the 7-day UCS results, laterite bricks were produced using soil-sand-cement mixtures with 0 and 45% sand content and 0, 3, 6, and 9 cement content. Laterite and sand were air dried for 24 hours before passing them through 10 mm sieve. Particles passing through the sieve were used

Soil-cement bricks produced from local clay brick
2020-12-1 Generally, soil-cement bricks are prepared from Portland cement, sand, and locally available soil such as laterite . Laterite is widely found in Thailand with many applications in construction . Commonly, the advantages of soil-cement bricks are ecological benefits, simple production, and good firing resistance [12,13].

Production and Testing of Lateritic Interlocking Blocks
2012-11-19 Laterite is a red tropical soil that is rich in iron oxide and is usually derived from rock weathering under strongly oxidising and leaching conditions. It forms in tropical and sub-tropical regions where the climate is humid (Mahalinga-Iyer and Williams, 1997). Laterite is very abundant in Ceylon, India, Burma, Central Africa, West Africa and Central America (Encyclopedia Britannica, 2001). It has been found to be less permeable when stabilised with palm oil, ordinary Portland cement (OPC) or clay from termite heaps (Encyclopedia Encarta, 2004). Because of the large deposits of laterite in Nigeria and most neighbouring African countries, the material is easily acquired and inexpensive. The potential of laterite is not presently being maximised in the area of brick production for building purposes. 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
