“…It is close to erosion sand in terms of grain size and has a tint of reddish brown colour which is retained when used. Lasisi and Osunade (1984) posited that the most economic sandcrete blocks can be made with common sand where the red tints associated with common sand is not a detrimental factor. Marine sand is often grained and fairly uniform in size.…”

Over 90% of physical infrastructures in Nigeria are being constructed using sandcrete blocks making it a very important material in building construction. It is widely used in Nigeria, Ghana, and other African countries as load bearing and non-load bearing walling units. For a long time in Nigeria, sandcrete blocks are manufactured in many parts of the country without any reference to suit local building requirements or good quality work. The Standard Organization of Nigeria (SON) developed a reference document which prescribed the compressive strength and water absorption properties standard requirements for different kinds of sandcrete blocks. The objective of this research is to ensure that all block manufacturers meets a minimum specified standard. The study appraised this objective using field study, sampling and laboratory experimentation and results obtained revealed very low compliance with as low as 0.66N/mm2 compressive strength value and as much as 16.95% water absorption capacity. The study revealed that poor quality control, poor selection of constituent materials and inadequate curing period by the manufacturers contributed to the negative results obtained.

“…Due to its environmentally friendly manufacturing process, studies are on-going to start artisanal or semi-industrial production. Several other studies [15][16][17][18][19][20][21] have shown that there is potential to produce building materials presenting good civil engineering properties with earth or lateritic soils.…”

Lateritic soils are formed in the tropics through weathering processes that favor the formation of iron, aluminum, manganese and titanium oxides. These processes break down silicate minerals into clay minerals such as kaolinite and illite. Iron and aluminum oxides are prominent in lateritic soils, and with the seasonal fluctuation of the water table, these oxides result in the reddish-brown color that is seen in lateritic soils. These soils have served for a long time as major and sub-base materials for the construction of most highways and walls of residential houses in tropical and sub-tropical countries of the world. Civil engineering applications of these lateritic soils are continually being developed with the use of different types of stabilizers. The stabilized soil-based products are as such viewed as environmentally-friendly and low-cost energy materials for sustainable building applications. This work aims at presenting a global view of what has been done in the field of lateritic soil improvement for construction purposes in tropical countries such as Cameroon. This shall be discussed through the presentation of the structure, composition and properties of lateritic soils, the various ways of improving their properties for construction purposes, the properties of products obtained and other prospects

“…Hasniza [1] noted that in accordance with the Ninth Malaysian plan, government also encourages publics to be involved in the Research and Development (R & D) in construction industry. One of the researches done in concrete technology is a study to find any material that can be used as a replacement material in concrete mixture [2]. The materials that show any likely potential to be used as a replacement material such as steel, latex, quarry dust, lateritic soil and glass are being investigated.…”

This is an investigation of weathering characteristics of Laterized concrete with laterite-fine aggregate ratio as a factor. It was done with a view of ascertaining the suitability of laterite as aggregate substitutes at 0, 10, 20, 30 and 40% of fine aggregate used in the construction industry. The weathering characteristics were examined by conditioning laterized concrete cubes to varying temperatures, chemical and alternate wetting and drying, which all represent the operating weather conditions (wet and dry seasons) in tropics, including Nigeria. The mix proportion used was 1:2:4, the curing age of the laterized concrete was based on 28days curing age, while the compressive strength of the treated laterized concrete cubes was determined. The result of this research showed that the compressive strength of laterized concrete with laterite-fine aggregate ratio variation decreases when subjected to alternate wetting and drying and increases when subjected to magnesium sulphate (Mg 2 SO 4 ). It was also discovered that a laterized concrete with a laterite-fine aggregate ratio of 20% conditioned to a temperature range of 100 o C attained optimum compressive strength of 12.90Nmm -2
