“…[27] reported sandcrete blocks compressive strength between 0.25N/mm 2 and 0.95N/mm 2 which did not meet the requirements of [28]. Also, in their studies [29][30][31][32][33] produced sandcrete using laterite, recycled waste papers, pulverized ceramics, and mineral wood fibers as river sand replacement.…”

Sandcrete is a construction material composed of cement, fine aggregate, and water. The constituent materials are in great demand due to their use in various buildings. The increasing demand in turn has led to astronomical increases in the cost of procuring these materials thereby making it very difficult to meet the shelter provision requirement of the teeming population of a country such as Nigeria. There have been various attempts to address this issue by substituting different materials for river sand in the production of sandcrete, either entirely or in part, one such material which is used in this research is bituminous sand. Bituminous sands are composed of sands, heavy oil and clay that are rich in mineral and water. Ordinary Portland cement was mixed with both river sand (as control) and bituminous sand in 0, 10, 20, 30, 40 and 100% replacement levels. Seventy-two sandcrete cubes were cast in all for this study and tested for compressive strength. From the investigation, the samples compressive strengths increased with increase in curing age and decreased with increase in percentage replacement though at a different rate with the sample containing 0% bituminous sand and 100% river sand denoted SC0,100 gaining the highest strength of 8.59N/mm2 at the 28th day of curing. The SC10,90, SC20,80, SC30,70 and SC40,60 attained 98.5%, 50%, 42.3% and 3.5% more strength compared to the design strength at 28th day of curing, respectively. While the SC100,0 attained 43.5% lower strength compared to the design strength at 28th day of curing. This research has revealed the possibility of using bituminous sand for developing eco-friendly sandcrete for construction purposes for up to 0-40% river sand replacement with bituminous sand.

“…Therefore, engineers need to consider this factor seriously, to ensure that sandcrete blocks and other concrete materials used for the construction of buildings comply with international and local building codes/standards (Erakpoweri and Onah, 2022). Sandcrete block which is a masonry unit is made from sand, cement and water; the cement acting as the binder from the composite material, while the water hydrates the cement which lead to chemical reaction that binds the sand and cement together (Sholanke et al, 2015;Awolusi et al, 2021). The percentage of the sand, cement and water used to produce the block can vary, and this variation is dependent on the specific requirements for the desired mechanical properties of the blocks (Akpokodje et al, 2021).…”

This study investigated the extent to which the mechanical strength of commercially produced sandcrete blocks in Delta State, Nigeria, conforms to recognized international standards. Fifty sandcrete blocks (28 curing days) were sampled from ten known sandcrete block manufacturers in Warri municipal area, five blocks from each manufacturer. The compressive strength of the blocks was determined in accordance with the American Society for Testing and Materials (ASTM) International guidelines. The results showed that the compressive strength of all the blocks failed to meet the Nigeria Industrial Standard (NIS) benchmark for load loading sandcrete block, while only 20% of the blocks attained NIS requirement for non-load bearing walls. Field observation revealed that poor mixing ratio of the sandcrete; inconsistencies in the batching method and sand used in the production of the sandcrete blocks were responsible for the poor quality (low compressive strength) of the sandcrete blocks manufactured in the region. The findings of this study underscore the importance for the Nigerian Institution of Structural Engineers, to rigorously monitor the strength of sandcrete blocks made in Nigeria to ensure that their quality meets internationally recognized standards. This will reduce the occurrence of structural damage in Nigeria, due to the use of low quality blocks for wall constriction.
